Replaceable and securely hashed keys from online signatures

Abstract

Incorporating the use of biometrics in cryptography has many advantages over the conventional use of passwords and keys. However, biometric data is non-replaceable, non-exact and requires template storage for comparison. We propose a secure method for generating biometric hash from online signature without template storag by incorporating user token and Wavelet-Fourier compression. Our results show good separation between genuine and forged signature keys. © IEICE 2006.
