The on-line spoof fingers detection algorithm presented here adopting ridge tracing features as input to Support Vector Machine (SVM) classifier. The wavelet transforms the coefficients of ridge data along ridges into sequences. The derived information relates to geometrical distribution of pores on ridges. As a result, it is more effective to distinguish pore information between spoof and live fingers...
Fingerprint authentication with small area sensor "touch sensor" becomes the most promising technology for network user authentication on mobile devices such as smart phones. In this situation, the size of touch sensors becomes so small that the conventional minutia method should be replaced with a new approach. We consider Scale Invariant Feature Transform (SIFT) approach for fingerprint...
