A New Security Scheme based on Palmprint Biometrics for Signature

摘要

This paper presents a palmprint biometrics technology for secure key management and signature; and a practical and secure cryptographic algorithm is proposed. The algorithm provides a method of generating reliably binary templates, or "biometric templates", from genuine palmprint image using 2-D Gabor filters. The biometric template can replace traditional password used for secure key management, which can protect the secrecy of the master key used for key pair generation before signature. A public key and corresponding private key can be created using the elliptic curve point embedding technique. Based on the above ideas, we use a pairing based signature scheme to perform signing and verification on the elliptic curve. Finally, the scheme was evaluated using 98 different person's right hands and proved to have higher accuracy and better FRR rates compared with the prior work.
