Fingerprint Quality Evaluation in a Novel Embedded Authentication System for Mobile Users

Abstract

The way people access resources, data and services, is radically changing using modern mobile technologies. In this scenario, biometry is a good solution for security issues even if its performance is influenced by the acquired data quality. In this paper, a novel embedded automatic fingerprint authentication system (AFAS) for mobile users is described. The goal of the proposed system is to improve the performance of a standard embedded AFAS in order to enable its employment in mobile devices architectures. The system is focused on the quality evaluation of the raw acquired fingerprint, identifying areas of poor quality. Using this approach, no image enhancement process is needed after the fingerprint acquisition phase. The Agility RC2000 board has been used to prototype the embedded device. Due its different image resolution and quality, the experimental tests have been conducted on both PolyU and FVC2002 DB2-B free databases. Experimental results show an interesting trade-off between used resources, authentication time, and accuracy rate. The best achieved false acceptance rate (FAR) and false rejection rate (FRR) indexes are 0% and 6.25%, respectively. The elaboration time is 62.6 ms with a working frequency of 50 MHz.

A Fingerprint-Based Verification Framework Using Harris and SURF Feature Detection Algorithms

“…All testing and evaluation experiments are performed on two public domain databases, widely used in the related works, namely the Fingerprint Verification Competition's FVC2000 DB1 [28] and FVC2002 DB1 [29] databases where each of them consists of a total number of 80 fingerprint images with a resolution of 300 × 300 pixels for FVC2000 DB1 and 388 × 374 pixels for FVC2002 DB1. Both datasets are publicly downloadable for free [30], in which the fingerprint images were acquired from ten persons; eight acquisitions for each person of the same finger [31]. For realistic fingerprint verification, a user initially needs his or her fingerprint to be fed into the fingerprint verification system which is saved in some format with the user's identity.…”
