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.
