Abstract: Aiming at problems in practical application of single biometric identity-based signature scheme, a novel multi-biometric identity-based signature scheme is proposed. The elliptic curve-based n-torsion groups are researched. Different biometric characteristics are syncretized. The biometric identity-based public key cryptosystem is introduced. Simulation experimental results show this scheme has better performances in security, stability and reliability, and is effective and feasible.
