A Review of Cancelable Biometric Authentication Methods

Biometric analysis for identity verification is becoming a widespread reality. Such implementations necessitate large scale capture and storage of biometric data, which raises serious issues in terms of data privacy and identity theft. Unlike credit cards and passwords, which can be revoked and reissued when compromised, biometrics are permanently associated with a user and cannot be replaced. In order to prevent the theft of biometric patterns, it is desired to modify them through revocable and non-invertible transformations to produce Cancelable biometric templates. This paper provides a review of the state of the art of different methods of biometric based authentication schemes and cancelable biometric systems. Ring finger crease Middle finger crease
