A Hadamard transform-based method for the design of ...
Abstract: Cancelable biometrics is an important biometric template protection scheme and can effectively address privacy and security concerns in the case of stored biometric templates being compromised. This paper presents a Hadamard transform-based approach to the design of cancelable fingerprint templates. The proposed cancelable templates are alignment-free and hence do not suffer from ......
 Alignment-Free Fingerprint Cryptosystem Based On Multiple ...
In the functional transformation method, transformation was based on a Gaussian function. However, all three methods required alignment before transformation. To align the fingerprints, these methods used singular points. Authors in [5] proposed a cancelable fingerprint template using fingerprint minutiae....
