A security architecture for reputation systems

Abstract

Reputation systems are emerging as a promising means to assist users to make a right decision about their counterparts before embarking on a business transaction with them in the e-commerce environment. Thus, it is extremely important to ensure that reputation systems are securely implemented and protected from manipulation. Motivated by such needs a security architecture for reputation systems is proposed. Within the architecture several services are identified. In addition, the mechanisms and parameters to support the identified services are also determined. © Springer-Verlag Berlin Heidelberg 2003.
