Abstract
Wolf attack is a new kind of biometric specific vulnerability and wolf attack probability is defined as a maximum success probability of the wolf attack with one wolf sample. From a theoretical point of view, a possible approach for describing wolf attack probability has been proposed in recent years, yet very little is known about practical approach in using a minutiae pattern. In this paper we propose a making method of wolf fingerprints to show vulnerability against simple count matching system. Even though this approach is valid only in a simple model, it is closely related to wolf attack against the real fingerprint systems. The experimental results show that wolf fingerprint using a minutiae pattern can get very high wolf attack probability.
