trip report from the tenth World Wide Web conference in hong kong
secure e-payments (TP4):
speaker: weidong kou & william song, university of hong kong
the three phases of e-commerce:
traditional payment methods:
- e-cash (or digital cash):
important properties are: security, anonymousness, portability, transferability, divisibility, infinite duration, usability, unit-of-value
- e-check (or digital check):
based on digital signature, secure, fast, easy to process
- on-line credit payment:
customer - agent - merchant relationship (agent settles payment between customer's and merchant's bank)
- CyberCash credit services:
analog to physical world credit card (requires authorization)
- customer side wallet:
stores client's credit card information in an encrypted file. bound to a particular PC, vulnerable to attacks and loss due to hardware failure.
- micro payment:
transaction value below USD 0.25. transaction cost must be less than the actual payment !
- SET (Secure Electronic Transaction)
developed by MasterCard and VISA, supported by IBM, Microsoft, Netscape, VeriSign and others. still no breakthrough yet.
nothing new ... we are still waiting for the break through of SET - or an alternate payment method ... and there is still no practical solution for the micro payment issue.
