一种可撤销匿名性的电子支付系统

An anonymity revoking electronic payment system

基于Ｆｅｒｇｕｓｏｎ电子支付系统，提出了一种可撤销用户匿名的支付系统．一方面，它能有效地保护用户的隐私．另一方面，在银行的协助下，一个可信第三方可撤销用户的匿名性。

An anonymity revoking electronic payment system based on Fergusons electronic payment system is presented. On one hand, the customers privacy cannot be compromised by the bank or by the payee. On the other hand, the anonymity can be removed by a trusted third party with the help of the bank. In this case, the third party can trace the money and prevent money laundering and black mailing.
