  2. 2. What is Electronic Payment?<br />Is a system that permits online payment between parties using an electronic surrogate of a financial tender <br />The electronic surrogate is backed by financial institutions and/or trusted intermediaries<br />The intent is to act as an alternative form of payment to the physical cash, cheque or other financial tender<br />
  3. 3. Electronic payment system<br />An e-commerce payment system facilitates the acceptance of electronic payment for online transactions. Also known as a sample of Electronic Data Interchange (EDI), e-commerce payment systems have become increasingly popular due to the widespread use of the internet-based shopping and banking.<br />In the early years of B2C transactions, many consumers were apprehensive of using their credit and debit cards over the internet because of the perceived increased risk of fraud.<br />
  4. 4. E-payment systems <br />There are numerous different payments systems available for online merchants. These include the traditional credit, debit and charge card but also new technologies such as digital wallets, e-cash, mobile payment and e-checks. <br />Another form of payment system is allowing a 3rd party to complete the online transaction for you. These companies are called Payment Service Providers (PSP).<br />
  5. 5. E-payment systems types<br />
  6. 6. E-payments<br />
  7. 7. Credit cards and smart cards<br />Over the years, credit cards have become one of the most common forms of payment for e-commerce transactions. In North America almost 90% of online B2C transactions were made with this payment type.<br />A Smartcard is similar to a credit card; however it contains an embedded 8-bit microprocessor and uses electronic cash which transfers from the consumers’ card to the sellers’ device. A popular smartcard initiative is the VISA Smartcard.<br />

  9. 9. Electronic bill presentment and payment<br />Electronic bill presentment and payment (EBPP) is a fairly new technique that allows consumers to view and pay bills electronically. There are a significant number of bills that consumers pay on a regular basis, which include: power bills, water, oil, internet, phone service, mortgages, car payments etc. <br />EBPP systems send bills from service providers to individual consumers via the internet. The systems also enable payments to be made by consumers, given that the amount appearing on the e-bill is correct.<br />
  10. 10. Current Status<br />ePayment opportunities are growing albeit slowly<br />New players are entering ePayment marketplace<br />Variety of ePayment mechanisms and devices - creating state of chaos<br />Infrastructure for ePayment is complex and expensive to deploy<br />Lack of critical mass adoption and acceptance<br />Online payment is hard to implement globally<br />

  33. 33. How can we secure ePayment?<br />The Trust Principle<br />The parties to the transaction must trust each other<br />Buyer must believe that seller is legitimate and will deliver the goods<br />Buyer must believe that goods are as represented and are worth the price<br />Seller must believe that buyer is legitimate and will pay for the goods purchased<br />
  34. 34. How can we secure ePayment?<br />The Security Principle<br />Parties need a secure environment in which to conduct the electronic transactions <br />Seller needs to protect the details of the transactions<br />Buyer needs to be certain that his/her information is securely handled and stored<br />Buyer needs to be certain that information is not stolen that it can be inappropriately used<br />
  35. 35. ePayment Solutions<br />Must providesecurity: resistance to fraud and online attacks<br />Reliable: highly available and accessible at all times <br />Cost effective: cost per transaction should be low even for micro-payment<br />Integrated and scaleable: interoperable amongst different systems, payment methods and multiple servers distributed across the Internet<br />Convenient and easy to use: should support several devices<br />Anonymity: should protect the identities of parties to the transactions and should not monitor the sources of finance<br />
  36. 36. Securing ePayments<br />Identification and authenticate<br />the ability to verify both the transacting parties<br />Authorization<br />the ability to validate the rightful owner to the transaction<br />Integrity and confidentiality<br />the ability to transmit the transaction securely<br />the ability to store the transaction properly<br />Accountability<br />The ability to provide audit trail as evidence in dispute<br />Policies for sharing risks and liabilities<br />the mechanism to settle disputes/non-repudiation<br />
  37. 37. Authentication Models<br />Something you have and something you know – ATM card model<br />Known to the back-end (server), synchronize with each transaction using a one time random number – Secur-ID model<br />“Sign” each transaction – PKI-model<br />Tie into a real person – Biometrics <br />

Secure Sockets Layer (SSL)<br />A security protocol to protect sensitive data transmitted over the Internet<br />Uses encryption to protect the transmission of data<br />When SSL session starts, server sends key to the browser, which returns random key to the server<br />Ensures that data are not tampered with or stolen en route<br />
  40. 40.
