Abstract :
In this paper we analyze the template protection method for minutiae-based fingerprint biometrics as proposed by Yang and Busch (BTAS 2009). This method is based on a self-aligning and non-invertible parameterized transformation that is applied to minutiae vicinities. Two attack strategies to invert protected vicinities are presented and we point out that the attack complexity is well below the estimates in the original paper. Improvements to increase the complexity are suggested.
