Cancellability for local binary pattern biometric authentication

Biometric cancellability enables protection and revocation of sensitive biometric data as used for authentication. This paper describes a cancellable biometric implementation by means of randomised Local Binary Pattern (LBP) feature vector, with user-specific secret-keys used to generate a biometric template. We also present experimental results to establish that authentication undertaken by our methodology is reliable, and also that the objectives of revocability and diversity are accomplished.
