An Anonymous Authentication Method for Toll Personalized Service
Jing Liu · 2008
Personalized service system provides differential services that satisfy the personalized needs of users. However, both generating and updating users’ models depend on private information, thus disclosure of privacy is possible. This could limit users’ willingness to use these personalized services. Basing on the pseudonymity of direct anonymous attestation scheme, this paper proposes an anonymous authentication method for personalized service in general networks. Some fringe improvements are also done for holding anonymity in a toll system. Theoretical analysis and experimental results demonstrate that the service provider can know whether a user is regular, and which access right the user has, but it cannot identify the user. Even if the service provider reveals access information, users’ privacy will not be endangered.
