The Electronic Commerce Challenge

Abstract

One of the biggest challenges in the development of electronic commerce has been for banks and merchants to overcome the issues of customer identification and account verification for online purchases. While the credit card systems have a process in place to verify and authorize transactions, the Internet poses challenges for merchants to not only validate that funds are available in an account, but to positively identify that the customer is in fact authorized to use that account for purchases.  

Early in the life of eCommerce, this situation led to the development of the SET protocol (Secure Electronic Transactions). While the initial version of SET was written in 1995, it has yet to be implemented for a number of reasons.  

More recently, there has been a standard proposed called x9.59 (Account Authority Digital Signatures, or AADS), which recognizes the necessity of binding a certificate to an account number. Lynn Wheeler , the author, appropriately summarizes the current situation in his document: "To make electronic commerce real, it will be necessary to demonstrate integration of public-key bindings into the core account-based business processes. This requires changes to the installed data processing implementations. Without this integration, there is little hope of deploying electronic commerce on a large scale."  

One of the biggest challenges in the development of electronic commerce has been for banks and merchants to overcome the issues of customer identification and account verification for online purchases. While the credit card systems have a process in place to verify and authorize transactions, the Internet poses challenges for merchants to not only validate that funds are available in an account, but to positively identify that the customer is in fact authorized to use that account for purchases.

In the physical world, merchants can validate the identity of the accountholder by comparing the signature on the credit card with the signature on the sales slip. But in a virtual world, where the customer is not present, the merchant does not know if that person is authorized to use the account number provided for the transaction. The danger in the eCommerce environment is that without some additional controls, the exposure to losses from fraudulent usage is exponentially greater.
