Evaluation of Contactless versus Contact Fingerprint Data, Phase 2 (Version 1.1).

摘要

The National Institute of Justice (NIJ) Sensor, Surveillance, and Biometric Technologies (SSBT) Center of Excellence (CoE) has undertaken an evaluation of fingerprint data gathered from traditional contact-based legacy fingerprint (LFP) devices versus fingerprint data generated by next-generation contactless fingerprint (CFP) scanners. In 2012, the NIJ SSBT CoE evaluated a biometric collection of fingerprint data from traditional scanners and next generation contactless devices – Contactless Fingerprint Collection, Round 1 (CFPv1). Based on the success of CFPv1 and its value to the biometrics research community, a second collection of contact and contactless fingerprint data has been performed (CFPv2). This report details experiments and analysis using the Phase 2 fingerprint data to investigate matching performance and interoperability of contact and contactless fingerprint devices. The analysis is focused on addressing the following objectives: 1. Determine the interoperability and match performance of CFP data against traditional LFP databases. 2. Investigate the performance and feasibility of a contactless fingerprint database for matching LFP and CFP systems against. 3. Evaluate the performance of criminal justice and/or defense relevant systems – fixed (i.e., livescan) and mobile devices. 4. Compare the match performance of data from CFPv2 with CFPv1.
