【 摘 要 】

Cancelable biometric techniques are becoming popular as they provide the advantages of privacy and security, not provided by biometric authentication system. It transforms a biometric signal or feature into a new signal or feature by some transformation. These are non invertible transforms to make sure that the original biometric template cannot be recovered from them. Most of the existing methods for generating cancelable fingerprint templates need an absolute registration of the image. Therefore they are not robust to intra user variations. But there also exists methods that do not require registration of the image. This paper provides a comparison between two such methods, one that needs registration and other that does not need registration.Keywords: Cancelable biometrics, non invertible transformation, registration, registration free.
