PRIVACY PROTECTION FOR USER AUTHENTICATION

The paper deals with Internet user privacy. We focus on the protection of user identity during an Internet service use. We start with an overview of systems for the anonymous channel creation. Such channels are necessary as any solution for the identity protection will have to work with the TCP/IP protocols used in the Internet. In the second part of the paper we argue about the need for an anonymous authentication introduction. Such a service is almost missing in the current Internet. We show how the concept of anonymous authentication could improve privacy and identity protection. Finally we introduce our concept for anonymous authentication with the feature of a malicious user detection.
