A consumer anonymity scalable payment scheme with role based access control

Abstract

This paper proposes a secure, scalable anonymity and practical payment protocol for Internet Protocol for Internet purchases, and uses role based access control (RBAC) to manage the new payement scheme. The protocol uses electronic cash for payment transactions. In this new protocol, from the viewpoint of banks, consumers can improve anonymity if they are worried about disclosure of their identities. An agent provides a higher anonymous certificate and improves the security of the consumers. The agent will certify re-encrypted data after verifying the validity of the content from consumers, but with no private information of the consumers required. With this new method, each consumer can get teh required anonymity level, depending on the available time, computation and cost.
