Dual Layer Structure Check (DLSC) fingerprint verification scheme designed for biometric mobile template protection

Recently biometric fingerprint mobile template protection has attracted research attentions. One major challenge is finding reliable biometric features that are robust against distortion and registration error. It is also desirable that raw fingerprints are not easily recovered once the template has been compromised. In this paper, we propose a new dual layer structure check (DLSC) fingerprint verification algorithm based on composite features which are reliable, distortion tolerant and registration free. The algorithm shows a great promise for incorporation into existing template protection schemes such as fingerprint fuzzy vault. In addition, the simplicity nature of our scheme makes it easy to be implemented on mobile devices at either software or hardware level. Our experimental results on public domain database FVC 2002 show that the scheme can achieve a low FRR with low FAR.
