A New Security Scheme based on Palmprint Biometrics for Signature

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.
