Departmental Bulletin Paper Network-based Fingerprint Authentication System Using a Mobile Device

Zhang, Qihu

Abstract— Fingerprint-based user authentication is highly effective in networked services such as electronic payment, but conventional authentication solutions have problems in cost, usability and security. To resolve these problems, we propose a touch-less fingerprint authentication solution, in which a mobile device's built-in camera is used to capture fingerprint image, and then it is sent to the server to determine the identity of the user. We designed and implemented a prototype as an application on the Android OS, onsisting of capture, preprocessing, and matching stages. The experimental results prove that our proposed solution using a smart device is feasible and it also serves to resolve some potential problems in the touch-based fingerprint technology. Keywords—Fingerprint Authentication; E-payment; touch-less; network-based; mobile device; Android
