A Practical Anonymous Off-line Multi-authorities Payment Scheme for Electronic Commerce

Abstract

We propose a practical anonymous off-line multi-authorities payment scheme. By means of our proposed scheme, the size of a bank’s database is dramatically reduced and distributed to shops. Also, the issue of e-coins is controlled by several issuers, who represent a bank and can be chosen by the customer or assigned by the system, on the current available issuers list according to the Internet condition.
