Electronic Commerce


Initially, the Internet was designed to be used by government and academic users,
but now it is rapidly becoming commercialized. It has on-line "shops", even
electronic "shopping malls". Customers, browsing at their computers, can view
products, read descriptions, and sometimes even try samples. What they lack is
the means to buy from their keyboard, on impulse. They could pay by credit card,
transmitting the necessary data by modem; but intercepting messages on the
Internet is trivially easy for a smart hacker, so sending a credit-card number

after the three-headed watchdog of Greek mythology, is one of the best-known-

generate the ticket during a series of coded messages ...

is faster. One way to factor out the
overhead is to use a trustee organization, one that collects batches of small
transaction before passing them on to the credit-card organization for
processing. First Virtual, an Internet-based banking organization, relies on
this approach. Consumers register their credit cards with First Virtual over
the phone to eliminate security risks, and from then on, they uses personal
