Secure Anonymous Conditional Purchase Order Payment Mechanism

摘要

In this paper, an Anonymous Conditional Purchase Order (ACPO) payment system is proposed which is an electronic payment system suitable for the real world. It not only keeps the high efficiency of previous buyer-driven systems but also strengthens the anonymity between customers and banks. The customers can advertise and put ACPO on the web according to their requirements, and then the merchants can evaluate which ACPO is appropriate for trade in any particular web site. Besides, timestamp will solve the problem of non-dispute and make our scheme more flexible. For example, customers can modify their ACPO to suit the merchant if they are not getting any response from the merchant with whom they want to trade.
