Biometric key generation based on writing force and trajectory
Zhou Guo-xiang · Journal of Computer Applications · 2009
In this paper, key generation algorithm was put forward to safely transform dynamic handwritten signature to biometric key based on F-Tablet, which used Fourier transform to extract feature and multi-state discretization algorithm to generate stable key. The authentication performance and security performance were analyzed through experiment. The key is hard to decrypt and easy to carry, can't be stolen and won't burden users with memory. And the key could be applied in identity authentication, file encryption and digital rights management and so on.
