Abstract

Privacy breach has become a major dispute in online transactions. In such a system, users give their personal information to get the service and that users‟ personal information may get wide spread across several organizations. Hence, there is a need for privacy protection. Private credentials offer authentication and authorization based on the traits possessed by a user not on the identity of the user. In this paper, we present a private credentials system that uses Schnorr Blind Signature based on elliptic curves. Elliptic curve defined over a prime field is chosen and ECDLP i.e., Elliptic Curve Discrete Logarithm Problem is the basis for the system. The properties of randomness, unlinkability, unforgability are preserved. The performance and storage space requirement of our system are compared with that of the cryptographic techniques that use discrete logarithm.
