On simultaneous latent fingerprint matching

Abstract

Simultaneous latent fingerprints are a cluster of latent fingerprints that are concurrently deposited by the same person. Though ACE-V methodology provides the scientific basis for matching latent fingerprints, extending it for simultaneous latent fingerprints is challenging. Further, there is a lack of automated or semi-automated algorithms to aid this process. The contribution of this paper is two-fold: (i) an automated two-level fusion technique for fusing evidences from multiple ridge impressions, and (ii) a simultaneous latent fingerprint database is created to drive research in this problem. The proposed algorithm yields promising results on the simultaneous latent fingerprint database.
