A Study on Performance Evaluation of Fingerprint Sensors

The performance evaluation in biometrics allows the developer to rapidly grasp the status of the current technology, as well as, to shorten the completion of commercialization. Also, this provides the reliability of the product to users and establishes a wide market. Especially for fingerprint recognition, the algorithm developers as well as users require objective and quantitative evaluation processes because the fingerprint recognition is the most unique technology in biometrics in the sense of various kinds of fingerprint sensors are being commercialized. The purpose of this research is to propose the process of performance evaluation, evaluation indices, and the presentation of result for fingerprint sensor modules. Four commercial fingerprint sensor modules have been tested and evaluated by comparing the quantitative measure of fingerprint image quality affected by environmental factors (temperature and humidity) and user factors (skin humidity and pressure). The result of this research is expected to be utilized for improvement of algorithms adapting to different fingerprint sensor modules.
