In this paper, we propose a protected on-line signature based biometric authentication system. The original signature templates are protected by transforming them in a non-invertible way. Recovering the original biometrics from the stored data is thus computationally as hard as random guessing. The transformed templates are compared employing a Dynamic Time Warping (DTW) matching strategy. The reported experimental results, evaluated on the public MCYT signature database, show that the recognition rates are only slightly affected by the proposed protection scheme, which is able to guarantee the desired security for the employed biometrics. © 2009 IEEE.
