Biometric Bit String Generation from Handwritten Signatures on Smart Device

Recently, with the rapid spread of smart devices, such as smart-phones and tablet PCs, biometric authentication using handwritten signatures on such devices has been attracting much interest. However, little research has been reported on biometric-bit-string generation from handwritten signatures, which is indispensable for biometric-template protection on smart devices. Therefore, for designing a more secure template-protection method for smart devices, we propose a biometric-bit-string-generation method from handwritten signatures collected on such devices. The simulation results confirmed the effectiveness of the proposed method.
