Abstract

Previously proposed anonymous electronic payment systems have the drawback that the bank has to maintain large databases, which is a handicap for the realization of such systems. In this paper, we present a practical anonymous payment system that significantly reduces the size of such databases. It uses the concept of anonymous accounts and offers anonymity as an add-on feature to existing EFTPOS systems.
