E-Commerce Assignment Questions 1. Investigate the regulatory landscape governing e-commerce security and data privacy, including GDPR, CCPA, and PCI DSS standards. Assess the impact of these regulations on e-commerce businesses and their compliance requirements. Develop a compliance framework and best practices for handling customer data, ensuring data privacy, obtaining consent, and maintaining transparency in data collection and processing practices. answer:Since the EU’s General Data Protection Regulation (GDPR) went into effect in 2018, at least a dozen different countries and states have either enacted new data privacy laws or strengthened existing ones – many of which share similarities with GDPR. Even within countries like the United States, recent years have seen the rise of state-level privacy legislation like the California Privacy Rights Act (CPRA) and the Virginia Consumer Data Protection Act (VCDPA). If you thought achieving GDPR compliance was tough, then imagine the complexity and effort involved in achieving regulatory compliance with several GDPR-like regulations, each subject to local legal interpretations of the concept of “data privacy” across each country where your business operates. In this post, we’ll show why you should use a data privacy vault to both improve the security of your sensitive customer data and simplify global data privacy compliance instead of taking a piecemeal approach toward satisfying individual privacy laws. Why Global Data Privacy Compliance Is Important Across every region where your business operates, you need to store and manage sensitive data in accordance with local data privacy laws or risk legal penalties that include fines or other sanctions. For example, say that your U.S.-based business collects personally identifiable information (PII), protected health information (PHI), and PCI data from users in both Australia and Brazil. If you are unaware of the data protection laws in place in these markets, you might send Australian and Brazilian residents’ plaintext sensitive data to your U.S. database as part of regular data operations to support workflows like analytics. But by doing so, you would be unwittingly violating laws in each of these markets that limit or prohibit such unapproved data transfers. Such violations of global data privacy laws can have negative consequences for your business, including: Hefty fines: Businesses of all sizes are subject to fines for data privacy violations. A large multinational business like Meta, for example, recently faced a fine of 1.2 billion euros under GDPR, while the same regulation was used to fine a local German chat website business 20,000 euros. Bad press: In addition to costly penalties, non-compliance with local data privacy laws can harm – and in some cases, even ruin – the reputation of your business. For example, in addition to facing a £18.4 million fine ($23m) after a 2020 data breach, Marriott International paid an even larger price when its share price dropped by 8.7% in the aftermath of this incident. Local bans: Violating data privacy laws like GDPR can get your business barred from operating in a particular country or region. For example, the Italian Supervisory Authority (SA) banned ChatGPT from operating in Italy on March 31, 2023, because OpenAI, a U.S.-based company, hadn't yet implemented an age-verification system to prevent the service from collecting data from children. This ban was subsequently lifted, but companies can’t count on local bans like this one being short-lived. How to Simplify Global Data Privacy Compliance with Skyflow You can comply with a wide range of data privacy laws across the world by using Skyflow Data Privacy Vault to isolate sensitive data, protect this data with a variety of tokenization and encryption techniques, and control who can see what, where, and when with fine-grained access control. Skyflow also lets you localize sensitive data so you can comply with data residency requirements, and supports securely sharing sensitive data with trusted third party services. Isolate and Protect Sensitive Customer Data Isolating sensitive data in a data privacy vault keeps that data away from your other systems, avoiding sensitive data sprawl and thereby reducing your compliance scope. And protecting sensitive data with multiple encryption and tokenization techniques not only preserves data privacy, it also helps companies to maintain compliance. Data Isolation and Sensitive Data Sprawl Sensitive data sprawl occurs when sensitive data is replicated as it’s copied and stored across various applications, databases, data pipelines, and logs — making it impossible to effectively govern access and increasing the work required to comply with data privacy laws and industry standards. You might store customer information in your customer relationship management (CRM) system, for example, which later gets replicated to your billing system, data warehouse, and analytics tools, even in 3rd party SaaS apps. Systems that contain plaintext sensitive data are part of your scope of compliance, meaning that they are included in any audits or certifications. When you start investigating the extent of sensitive data sprawl in your systems, you’ll probably discover that sensitive data is present nearly everywhere, as shown below: An Architecture with Sensitive Data Sprawl With Skyflow, you avoid sensitive data sprawl by storing plaintext sensitive customer data in Skyflow Data Privacy Vault. Instead of handling plaintext sensitive data, your CRM system, billing system, data warehouse, analytics, and other systems handle tokens that point to this data. Skyflow lets you structure these tokens in a variety of formats to avoid input validation issues. With sensitive data isolated in Skyflow, the example architecture shown above now looks like this: An Architecture with Sensitive Data Isolated in Skyflow Data Privacy Vault Now that we’ve covered data isolation, let’s look at how data protection simplifies global data privacy compliance. Data Protection and Global Data Privacy Compliance One thing that all global data protection laws have in common is that they mandate the protection of sensitive data from data breaches and restrict the use of this information. For instance, Article 25 of the GDPR, Principle 3 of the Australian Privacy Act, Section 24 of the Singapore Personal Data Protection Act, Section 2 of the South Korean Personal Information Protection Act, and the HIPAA de-identification standard all require limiting the use of personal data to specific, authorized purposes. And, these laws also require businesses to implement security measures that prevent data breaches. One way that you can use Skyflow Data Privacy Vault to limit the use of personal data is by de-identifying sensitive data records. For example, if your customer service agent (CSA) workflow only requires the last four digits of a credit card or social security number (SSN), you can use Skyflow to only reveal the last four digits to authorized CSAs. This limited information gives a bank employee or a healthcare billing agent what they need to verify the identity of a customer or patient without needlessly disclosing the complete SSN or credit card number. Skyflow Data Privacy Vault also uses polymorphic encryption, a method that lets you run operations on fully encrypted data without the need to decrypt it first. For example, you can use polymorphic encryption to answer questions like “Is this customer’s credit score above 650?” without actually decrypting that customer’s credit score. Or, you could polymorphically encrypt patient SSNs and run match operations on them to verify a patient’s identity. And, you can do the same with any other ID number, not just SSNs. Implement Data Residency and Fine-Grained Access Control Your business must establish effective data governance with fine-grained access control to comply with data privacy laws and data residency requirements. When it comes to data residency and sovereignty, Principle 8 of the Australian Privacy Act, Article 9 of the GDPR, and other data privacy laws impose specific conditions that restrict when sensitive data can leave the country or region of origin. You can ease compliance with data residency requirements by storing all of your sensitive data inside multiple Skyflow vaults that protect sensitive data from each region where data residency requirements are in effect. For example, you can have one vault located in Brazil to manage the data of Brazilian residents, and another vault in the EU to manage the personal data of EU residents, as shown below: Using Regional Skyflow Vaults to Ease Data Residency Compliance In addition to managing residency requirements, you’ll also need a way to control who can access what data or format. For example, the customer support agent (CSA) of an insurance or billing company doesn’t require the entire social security number (SSN) to verify patient identities. So, instead of allowing CSAs to access the entire SSN records of all patients, with Skyflow, you can restrict access with a policy such as: By redacting all but the last 4 digits of all SSNs, you keep sensitive data out of your CSA workflow. Skyflow lets you define your own data types, so you can customize this behavior for other data types, including ones that you define, not just for SSNs. You could also extend the policy shown above to make it specific to residents of California and aid with CPRA compliance. All you need to do is add a WHERE qualifier to your policy: Using the APIs and SDKs provided by Skyflow Data Privacy Vault you can establish new data governance policies, implement fine-grained access controls and assign roles and attributes for each resource without developing any custom software. Skyflow Studio gives administrators an intuitive user interface that makes it easy to maintain and update all of your policies. Securely Share or Transfer Sensitive Data Most data privacy laws, including GDPR, PIPEDA, PDP, POPIA, and LGPD, strictly limit or prohibit the transfer of sensitive data outside the region where the data originates. But your business needs to share data in some form with external entities such as payment processors, vendors, and third-party software tools. One way that Skyflow addresses these needs is by swapping sensitive data with non-exploitable tokens. Because these tokens don’t contain any sensitive data, you can freely share them with trusted third party services without risking non-compliance. And when required, authorized parties can de-tokenize these tokens to retrieve plaintext sensitive data. Skyflow’s Tokenization Replaces Sensitive Data with Non-exploitable Tokens Additionally, Skyflow offers secure connections to any third-party API, from a card payment network like Visa to a check issuance service like PostGrid. These connections allow you to securely integrate trusted third party services and tools into your offerings to support scenarios like card issuance and payment orchestration. To see how Skyflow can help your company to implement global data privacy compliance, including such aspects as PCI compliance and data residency, consider Apaya. Apaya Uses Skyflow to Protect Sensitive Data and Ease Global Compliance Apaya, a no-code payments automation platform, is quickly scaling operations across Europe, the Middle East, and Africa. To comply with PCI DSS and the various data privacy laws in these regions, Apaya needed to protect sensitive data, implement data governance, and meet data residency requirements. Instead of building these capabilities in-house, Apaya partnered with Skyflow to build a modular and scalable solution. Today, Apaya uses Skyflow vaults located in the Middle East and Europe to capture, tokenize, and store sensitive PCI data. Each vault stores all sensitive data records within the region and sends tokenized data to trusted third-party payment processors. As a result, Apaya can provide its customers with seamless custom payment flows and ease their compliance burden. Apaya’s Architecture Eases PCI and Data Residency Compliance in the Middle East and Europe 2. Investigate common payment security vulnerabilities and fraud risks in e-commerce transactions.

Here’s a list of some serious security issues and insider threats that lead to serious damage to both individuals and payment gateway development organizations. List of Critical Issues of Fraud With Online Payment Systems 1. Identity Thefts: The major cause of this threat is unauthorized access to the personal information of the users who have not prevented the same. This unauthorized access can lead to identity theft, allowing the fraudsters to make unpermissible transactions on behalf of the users. Such thefts can make you suffer huge losses while you are making online payments using an unsecured payment mechanism. 2. Phishing Attacks: Fraudsters often create deceptive e-mails, messages, or web pages in such a way that they look just like a real payment page. It is done mainly to trick the users so that they can reveal their sensitive and confidential information like IDs and passwords or credit card or bank account details. These details can be further used by hackers to wipe off your bank account with ease. 3. Data Breaches: Most of the payment gateways are equipped with different vulnerabilities that are responsible for compromising the payment system’s database. Resulting in the theft of large amounts of user data. After which the attackers expose such data of different individuals to further process potential fraudulent practices with those individuals. It not only causes the users to suffer huge financial losses but also compromises the payment business’s reputation in the market. 4. Weak Authentication: Inadequate authentication mechanisms like weak or discoverable passwords in your accounts, or when the users have not implemented multi-factor authentication over their online payment platforms. Allows unauthorized users to easily access your account, resulting in the wiping up of your savings. Weak authentication can make your payment account prone to data breaches and security issues. 5. Mobile Wallet Vulnerabilities: Data security vulnerabilities in mobile payment apps and digital wallets can lead to serious security issues. These vulnerabilities provide easier access to unauthorized users, allowing them to access your payment details or enabling them to manipulate your transactions, shifting them to their payment mechanisms. 6. Online Transaction Reversal Fraud: Fraudsters exploit or discover loopholes in your payment systems and their transaction procedures. Resulting in the reversal of the legitimate transactions made by the users or they can also conduct transactional chargebacks without letting the individuals informed about the same. 7. Inadequate Encryption Mechanism: Deploying inefficient and inadequate encryption mechanisms to online payment systems results in insufficient encryption of data during its transmission and storage in the database. It leads to the exposure of sensitive information to unauthorized users so that they can access it to practice fraudulent events with your payment systems.

Post demonetization there has been and hike in digital payment which opened the gate for multiple digital wallet to enter India and have a successful run in the long run. The aim of the study is to see the reasons examined by differed authors for adoption of digital payment by people. Keywords: Communication, Technology, Internet, Digitalization, Digital Payment. 1. Introduction The growth of Information and Communication Technology has bought a lot of changes in the lifestyle of the people .ICT and digitalization has bought great advancements if fields of finance, marketing, economics operation, etc. (Slozko & Pelo, 2015).In the period of Digital innovation and ICT there have been a lot of changes in the world where business transactions have shifted from cash to digital once. (Muhamad, Haroon, & Najiran, 2009).The arrival of development in technology in the worldwide business environment had challenged almost all organizations to shift from traditional paper currency to digital payment platforms which is commonly known as digital payment or e-payment system. Digital payment can be defined as platform which is used for making monetary transaction for various goods or services purchased over the internet. (Roy & Sinha, 2014). With the introduction of digital payment system the payment system in the world had to shift its method of payment to align with the current or latest payment technology for individuals, organizations, businesses, government, etc.(Odi & Richard, 2013).The digitization has forced to change the payment system around the world from paper, coins , people stated to shift towards the digital payment system as it was very fast , convenient, and beneficial for individuals, organization(Premchand & Choudhury,2015). Digital or E-Payments are very important mode of payments used by the population which is a very secured, fast and convenient mode of making any payment using the internet and it is also an opening for an economy to grow and excel its technological advancement in the world economy (Slozko & www.ijcrt.org Further adding to it at has become a great facilitator to the e-commerce as they are heavily dependent on digital payment. Digital payment not only provides the e-commerce or e-business with advance money but it brings in efficiency ,reduced cheat activities and its adding on to the new innovation in the payment system across the globe (Oladeji,2014). Furthermore, digital payment system engages many digital or e-payment system which many financial institutions are able to provide easy services to their customers such as debit cards, credit cards, net banking, etc.( Premchand&Choudhury,2015).The rise of this mode of payment system is having a great increment in adoption in today’s time (Balogun,2012).As there is so much of convenience and benefits associated with digital payment, there is still a a lot of concern about the security that the ICT knows and they are working to resolve this fear of security which is the only concern about this payment system mong all users and experts (Khairun & Yasmin,2010) 1.1. Definitions In the past 20 years there has been an evolution of the digital payment which started to get slow attraction from users, researchers as it was bringing change in the modern e-commerce. As it was getting attraction the researcher’s started to define it in various ways it focused on various fields namely business, IT, accounts & finance. According to Briggs and Brooks (2011) digital payment is a form of payment which is supported by banks and inter connected between individuals and banks for making monetary transaction digitally. Peter and Babatunde(2012) saw digital payment as a mode of payment ,transaction or transfer of money with the help of internet. In the same context Adeoti and Osotimehin (2012) referred digital payment as an way of making payment online or in any particular place using the digital mean. Kaur and Pathak(2015) suggested that digital payments are payments which are done for e-commerce purpose where money is exchanged through digital mode. Going by the above definition we can conclude that digital payment is a mode of payment which involves various digital platforms or application to make transaction, using digital means. 1.2. Digital Payment 1. Plastic Cards- These are cards issued by banks to their account holder, by using it they can withdraw money from any ATM by using their password. These cards are used for depositing money in banks to so that there is less wastage of paper. There are two type of cards issued by banks i.e. debit and credit card. Debit cards are issued to all account holders whereas credit cards are issued to the once according to their interests. 2. UPI -Unified Payment Interface is a payment mode this is used to make fund transfers through the mobile app. One can transfer funds between two accounts using UPI apps. One should have a registered mobile banking facility to use UPI apps. Currently, this service is only available for android phone users. One can download a UPI app and create a VPA or UPI ID. There are too many good UPI apps available such as BHIM, SBI UPI app, HDFC UPI app, Mobile, PhonePe app etc. It is not mandatory to use the UPI app from a respective bank to enjoy UPI service. One can download and use any UPI app. 3. Mobile Wallet-It’s the other way of storing or keeping digital cash and using it for various transactions. A person can download any mobile wallets namely Paytm, GPay, Phone pay, Sbi buddy, Jio money, etc. They just need to link there bank account or their plastics cards number to use the amount required and which is further used for making payments, paying bills etc. 4.Internet banking- There are various types of internet banking which are NEFT(National Electronic Fund Transfer), RTGS(Real Time Gross Settlement),ECS(Electronic Clearing System), IMPS(Immediate Payment Service).These are e-banking system which allows individual or organisations to make transfers using the website of their banks. www.ijcrt.org 5. Mobile banking- It is provided by all banks to their customers where the customers need to download the application of the bank and they cause it for making transactions. For using such application on should have a smartphone. There are many more types of digital payment available in our country and across the globe we have talked about a few which are known to people. 2. Literature Review Kevin Foster, Scott Schuh, and Hanbing Zhang (2010)they examined the consumer payment methods with respect to cash holdings and withdrawals which was decreasing since 2010.There was an increase in card payment system with respect to 2009 in the year 2010, which resulted in less usage of paper currency. Since 2010 there was an increase in usage of debit and credit card compare to cash transaction which slowly took a decline giving rise to prepaid payments. Singh.A et.al (2012) in their study discussed how secure the internet network should be to make smooth transaction for all the parties and the merchants. The systems are made in such a way so that there is no fraudulent activity takes place people can use their card for transaction in a secure way so that no data is shared. People mostly do digital transactions for e-commerce but they find internet I not secure to do so. Therefore some strict protocol should be followed and managed to make transaction secure and the data is also protected. Oladejo, Morufu et.al (2012) in their study examined the improvement of e-payment system in Nigeria. They explored what initiated the people to adopt the e-payment system. A structured questionnaire and some financial statements were collected to analyse the data. The results were such that when bank adopted e-payment system there was a change in the performance level of the banks. With the advent of e-payment system there was a rise in usage of ATMs. Nitsure (2014) in his study highlighted the issues that were being faced or observed in developing country like India in using the e-payment system which was due to the low spread of internet and technology. The paper focused on major issues such as security, rules, etc. IN a country like India there is a high risk where the poor’s are given a chance to be informed about such facilities neither they are given any such information. Rakesh H M & Ramya T J (2014), in their study analysed the factors that which was resulting in the adoption of internet banking in our country. It was found out that perceived reliability, Perceived ease of use and Perceived usefulness were the main reason for the adoption or usage of internet banking. Sanghita Roy, Dr. Indrajit Sinha (2014), discussed in their paper that in India there has been a sudden surge in the usage of digitalised payment. But still there is almost 90% transactions which are done through paper currency. They had used the TAM (Technology Acceptance Model) in this study to find out the factors which are strengthening the e-payment system the factors are innovation, incentives, and legal frame work and customer convenience. Dennehy & Sammon (2015) has analyzed how in the 21st century the usage of digital payment has increased over the years. The main focus here was to find out how where will in the digital payment system in future stand. Many papers have been examined to find out what are the views regarding the digital payment system. With the passage of time the technology has been shifting very fast so with the innovation of technology the aim was to make people familiar with digital payment. The merchants also got a new platform to invest so as to cater the customers. Data was collected by following empirical method i.e. survey, interviews, etc. Lastly the study was only focused on Google data base that was a limitation about the study. www.ijcrt.org Sanaz Zarrin Kafsh (2015) made a study on “Developing Consumer Adoption Model on Mobile wallets in Canada”,in her study she did convenience sampling from were 530 respondents were selected and there after the Partial least square model was used to test the data.As per the analysis the result perceived usage, perceived ease of use and perceived security is related to each for forecasting the adoption of digital payment. Bezhovski (2016) has examined how internet and e-commerce has opened the gateway for digital payment system with the increment in technology people are adopting the new means of payment system and how they will be benefited and is there any pitfall of using it. When e-commerce was launched it was a unique way of trading so the digital payment is also a unique way of transaction which will also emerge as the e-commerce and in near future it will become the backbone of e-commerce. The future of these digital wallets will depend on the security and privacy that are provided by the companies as people are highly security concerns any pros and cons will decide the future of digital wallets. It is not only restricted to make transactions but it be used for booking airlines, movie tickets. Many offers are provide for making bill payments or buying any goods using these platforms. As the smart phones has removed many devices from our daily live and have clubbed in one device only so it is expected that digital wallet will also do the same which will become substitute for many other things. Ravi (2017), has examined that India’s two third population are residing rural areas so they play a very important role in the development of the economy, with the emergence of IT and Communication it is predicted that rural areas will have 50% of India’s Internet users by 2020.Digital wallets should be used in rural places so that the people know the significance of using it and what benefit they will be getting by using it. The Government of India has also taken up the initiative of making rural people aware about Digitization. Adoption of technology has always been low in India compare to other countries but in case of Digital wallet our country is going with the pace of other countries to become a cashless economy. As the two third population of India is in rural part so if the rural people with time adopt the digital payment system then in the coming years India will become a cashless economy. The government of India has taken up various initiatives to make the rural people become familiar with digital wallet. The urban people have adopted the digital system of payment, now it’s time for the rural people too. If the rural people are made aware about digitalization soon it will roll out all over India. The best step that the National Payments Corporation of India has taken is that digital wallet will work on all mobiles with or without internet. Singh (2017) in his study showed that how digital payment and digital wallet in India was get popularized due to demonetization. As there was a tremendous growth in the usage of internet and the no. of smart phone users were also increasing so people found it convenient to use as an alternative for cash. In this study he also pointed out that how different digital wallet companies were having competition to enter and expand the Indian market as it was the best opportunity for them to establish their company. It was also predicted that in future India will become a cashless economy and with digitalization people will surely adopt the digital mode of payment. ANOVA was used in this study to show that there is no significant variance in the consumer perception with respect to its demographic factors. Baghla . A (2018) in his study identified the trends for adopting the digital payment system India. Further the paper talks about how after demonetization people started to use the digital platforms for transactions. How the government initiative to make our economy a cashless one and how consumer will be adopting such system are further discussed. A structed questionnaire was used to collect data and find out the future of digital payment system in India. www.ijcrt.org Pandey and Rathore (2018) in their study discussed the impact of digital payment system. Due to modernisation and globalisation it was very important for the people to accept the modern method of payment. The study is based on secondary data and various literatures from past papers and government data. All data collected has been analysed and used to find the impact and adoption of digital payments by the people. Pushpa S. Abbigeri and Rajeshwari M. Shettar (2018) talked about how the Digital India flagship program attracted large number of people to start using digital wallets , which people started to use as there was lots of cash back offers and coupons. After the digital India flagship program a lot of mobile wallet companies entered India and other methods such as UPI, NEFT to a surge. The initiative taken by the government and RBI was being accepted by the people as they were using such methods. Shivathanu B.

SECURITY THREATS AND SOLUTIONS Security threats related to digital payment will evolve day by day. Some of common threats are Trojan. Trojan is malware where is acts as genuine software of the users but behaves the way it wants. Trojan can reach users Personal computer( PC ) or Phone through email along with PDF or downloadable links. It can track keystrokes, make system vulnerable to other attacks. It will change original data form, copy important information, update data if required, use system resources for its own task and hinder system performance. Comparing other viruses, Trojan don't have capability to duplicate itself . Trojan can act in multiple ways, Backdoor Trojan where it will not attack your system instead will open doors for other attackers to manipulate your system, it achieves this by loading variety of malware to victim system which makes system vulnerable. Rootkit will make sure that victim will not any malware on his/her system. Banking Trojans are those which captured screenshot during payment transaction with keystrokes capturing. Remote access Trojan gives attacker a way to access victims system remotely, similar to banking Trojan even this can capture screenshot of transactions. Trojan works in following, first it get downloaded to victim's system by escaping victim's awareness. Then Trojan gives remote working environment for attacker to deploy more malware to victim system. To this point victim system is under control of attacker. With respect to digital payment, attacker can target sensitive information like credit card details, transaction data, login and usage logs. They are good at hiding their presence on the victim system with the help rootkit type of virus. As mentioned earlier Trojan has capability to capture keystrokes which in turn leads to collect user credentials like username and password. In some cases it also captures screenshots, if you want context of screenshot with digital payment where attacker can take screenshot of transaction of victim. Denial of service is the Cyberattack, where the third party tries to flood your system with hundred's of requests. This makes platform to break down and unable to provide service for users in turn recurring losses. Worms are more dangerous because it does not need attacker intervention. It can act on its own, meaning it will duplicate itself and spreads across many devices. One way it attacks is using Distributed denial of service (DDoS).In which it compromises as many as devices in the network and will flood the network as many request to bring the system eventually making financial loss to platform, service being unavailable to users. In digital platform it can also take advantage of code not written properly, networks. phishing attacks comes Cyber threat where attackers act as trusted platform to communicate with unsuspecting user via mail, text or website. attackers make sure he acts like trusted platform to get user credential or other sensitive information from the user. Solution to prevent oneself from malware and attacks is keep antivirus up to date. This software detects and eliminate malware. Anti-virus companies releases software updates regularly so with those software updates software can perform and detect new viruses in the market. one more thing users can do is to use firewall which stands between device and foreign network ensuring logging of all activity. By enabling firewall will reduce the chances of system being compromised. users should be educated on where to download files; cause Trojan are usually hidden in the PDF upon which downloading can transfer it system directly. Make use of Encryption technique like SSL and TLS which encrypt connection between entity during transaction.

ENCRYPTION TECHNIQUES Encryption techniques play an important role in maintaining the security and privacy in digital payment systems. By applying many algorithms bland by doing so organizations can ensure the integrity, confidentiality, and authenticity of data during payment transactions. In this section, we will delve into the encryption techniques commonly utilized in digital payment systems, highlighting their significance in bolstering security and privacy. SYMMETRIC ENCRYPTION Symmetric encryption stands as a foundational encryption technique widely embraced by digital payment systems. It operates by employing a single secret key for both encryption and decryption processes. This shared key between the sender and the recipient serves to establish secure communication channels and safeguard sensitive data. Notable symmetric encryption algorithms commonly employed in digital payment systems include: AES (Advanced Encryption Standard):} AES is widely called a symmetric block cipher due to its effective performance and strong security measures. It supports key lengths of 128-bit, 192-bit, and 256- bit, providing a high level of encryption to ensure secure data transfer from one place to another. 3DES (Triple Data Encryption Standard):} On the other hand, 3DES uses the Data Encryption Standard (DES) algorithm by adding additional three consecutive encryption operations in a cascade. This approach enhances security by adding multiple layers of encryption to the data. While DES may be deemed relatively weak, the utilization of multiple encryption rounds within 3DES significantly bolsters security. Symmetric encryption techniques enable the encryption of sensitive information, such as credit card details and transaction data, thereby guaranteeing its confidentiality and impeding unauthorized access. ASYMMETRIC ENCRYPTION Asymmetric encryption, also widely called public-key encryption, is an important technique used in digital payment systems. It operates using a pair of keys: a public key for encryption and a private key for decryption. While the public key can be freely shared, the private key is securely kept by the intended recipient. This approach ensures secure and unscathed communication between senders and receivers involved in digital transactions. The following benefits are provided by asymmetric encryption: Secure Key Exchange: Asymmetric encryption helps in the secure exchange of keys between senders and receivers involved in a transaction. This ensures that session keys or symmetric encryption keys can be securely transmitted over any network, providing excellent protection against eavesdropping and unauthorized access. Electronic Signatures: When ensuring the authenticity and integrity of digital price transactions, digital signatures are absolutely necessary. When a digital signature is created using the sender's private key, the recipient can use the corresponding public key to validate the signature. Confidentiality: Confidentiality is another crucial feature provided by asymmetric encryption, which allows data to be encrypted using the sender's public key. Only the intended recipient, possessing the private key, can decrypt and gain access to the information, which significantly improves its confidentiality and privacy. Prominent asymmetric encryption algorithms commonly utilized in digital payment systems include: RSA (Rivest-Shamir-Adleman): RSA stands as a widely recognized encryption algorithm celebrated for its security and versatility in key exchange and digital signatures. Elliptic Curve Cryptography (ECC): ECC offers robust security while employing shorter key lengths compared to traditional algorithms. This feature makes ECC particularly suitable for resource- constrained environments. By implementing these encryption techniques, digital payment systems can fortify their security measures and safeguard sensitive data, ensuring a trustworthy and protected environment for payment transactions. HYBRID ENCRYPTION To harness the advantages of both symmetric and asymmetric encryption, hybrid encryption procedures are commonly utilized in digital payment systems. In this approach, symmetric encryption is used to encode the actual payment data, while asymmetric encryption is used to securely exchange and safeguard the symmetric encryption keys. By combining these encryption techniques, digital payment systems can ensure secure and confidential transactions, safeguarding sensitive data from unauthorized access, alteration, and interception. In conclusion, encryption techniques are vital components in addressing security and privacy concerns in digital payment systems. Symmetric encryption provides efficient and secure data transmission, while asymmetric encryption facilitates secure key exchange, digital signatures, and confidentiality. By employing hybrid encryption approaches, organizations can leverage the strengths of both techniques to enhance the security and privacy of digital payment transactions, thereby building trust and safeguarding sensitive information. FRAUD DETECTION AND PREVENTION Fraud detection is to take care of transaction occurring through internet. There are security concerns like unauthorized access is where person who does have any rights on platform access the platform like hackers and cyber criminals employ techniques like phishing and denial of service. Data breaches can happen when system is under control of attacker/ compromised, which attackers can get access to personal information like credentials . malware/ransomware will also cause a threat which can take control of victim's system. Privacy concerns like data collection from user ensures that user on platform are legitimate. This can be ensured by collecting necessary details like transnational details, device information which are necessary for prevention and detection of frauds. Data security should be implemented so user's data is in tact so attacks on data is detected. secure storage devices, encryption can help data security. user should be consented for which data is collected from them so they understand why those data are collected. Data retention policies should be know to user and it is ethical role of data collectors to dispose data. User should have right to see, access, and update data collected by them to the platform. Few measure are taken to prevent are Multi factor authentication and real time monitoring. Two factor authentication adds one more step on entering password which user know and user were asked to link something like email or phone number which are belonging of user, where it significantly reduces the unauthorized user into someone else account. conventional method like entering password is vulnerable to phishing, brute force attack or social engineering. In Two factor authentication, first part is user password or user pin that user knows and want to keep it secret but the problem password faces is that is can be easily compromised using phishing or key logging. It can be easily figured out by cybercriminal. Second part of Two factor authentication is thing which user owns and can be used to get entry to the platform. Commonly used factors are OPT, Notification sent to user phone. OTP (one time password) is sent to user's phone app, text or email which user can enter after entering password which send the second factor to you. Real time monitoring tracks transaction currently happening over network or continuous monitoring of transaction either by collecting location, amount, user behavior. Key components of real time monitoring is transaction monitoring which use machine learning algorithm to analyze transaction. It includes velocity checks, outlier identification which helps to understand any behavior which is abnormal. Collects data from multiple sources where it includes data lie customer information, organization information which helps in fraud detection. Behavior analysis tries to read the history of user's transaction to verify their previous behavior and current behavior to identify any potential fraud and makes it easy to prevent it. Network monitoring is key component of real time monitoring where not only user's profile is monitored to prevent fraud but entire network is monitored to identify any distributed denial service of attack or any system breaches. But one more thing to remember is apart from the above key components constant improvement to identify new malware, new machine learning algorithms to analyses network or user profile should be discovered to mitigate new fraud and prevent it from occurring.
