A study on the E-cash system with anonymity and divisibility

Abstract

The micropayment system offers ways of payment in electronic commercial trades in accordance with the purchase of a commodity. The ways of payment include credit cards, on-line money transfer, electronic cash, and others. Electronic cash has been developed to complement the weaknesses of real currency for the sake of electronic commercial trades, and has many requirements and security measures to be met so as to be used like real currency. The author has analyzed the anonymity of electronic cash, among the many requirements and security measures, in order to come up with effective and safe ways to offer anonymity for the micropayment system. © Springer-Verlag Berlin Heidelberg 2005.
