A fully anonymous electronic payment scheme for B2B

Abstract

In this paper we present a fully anonymous (for payer and payee) electronic payment scheme for B2B transactions involving high amounts, without using tamper resistant devices, without pseudonyms, and preventing double spending. Schemes with detection of double spending at deposit are not well suited for high amount transactions (merchants and banks don't want to assume potential high losses). Our scheme allows anonymity revocation in case of illegal activities (using prevention techniques). © Springer-Verlag Berlin Heidelberg 2003.
