Biometrics is an emerging technology for user authentication. However, biometric data is generally non-revocable unlike a password (as it is not possible to change it). To overcome this problem, biometric template protection schemes have been proposed in the last decade. The purpose of this paper is to study the robustness of a popular algorithm carrying out attacks achievable by an attacker. Experimental results on a significant fingerprint benchmark show a good robustness of this protection scheme against personal attacks (identity theft) but also some gaps in identification applications.
