Table 5 Major advantages of BCS and CB.
From: A survey on biometric cryptosystems and cancelable biometrics
Advantage | Description |
|---|---|
Template protection | Within BCSs and CB the original biometric template is obscured such that a reconstruction is hardly feasible. |
Secure key release | BCSs provide key release mechanisms based on biometrics. |
Pseudonymous Auth. | Authentication is performed in the encrypted domain and, thus, is pseudonymous. |
Revocability of templates | Several instances of secured templates can be generated. |
Increased security | BCSs and CB prevent from several traditional attacks against biometric systems. |
More social acceptance | BCSs and CB are expected to increase the social acceptance of biometric applications. |
