Video-based fingerprint verification

In this paper, fingerprint videos are used to improve the accuracy of a fingerprint verification system. We define the “inside-similarity” and “outside-similarity” to represent the similarity within a video and between two videos, respectively. A new method is proposed to define and calculate the matching score of two videos according to the similarity and the effect on the error probability of this method is analyzed theoretically. Experimental results confirm our arguments in the analysis and indicate that the proposed method can lead a much better performance than the method using a single impression. Therefore, we believe that video-based method is an effective approach to improve the accuracy of fingerprint system.
