Abstract
Recently, with the rapid spread of smartphones and tablet PCs, biometric authentication using handwritten signatures has been attracting much interest. However, little research has been reported on biometric template protection, which is indispensable for protecting one's privacy, especially when those devices are used in a network environment. Therefore, as a means of (biometric) template protection, we propose a common template-based biometric cryptosystem that is suitable for signature-based biometric authentication. The results of the simulation using signature data confirmed the effectiveness of the proposed method.
