基于动态手势的身份认证方法及其在智能手机上的应用
An Identity Authentication Method Based on Dynamic Gesture and Its Application in Mobile Phone
摘要
Abstract
Biometric authentication is a hot topic in the current information security field .Based on the analysis of the current biometric authentication methods and the problems of their applications on smart phones ,we propose an identity authentication method based on a dynamic gesture matching algorithm named EI-DTW ,which combines relaxation of the endpoints restriction and early termination of authentication based on dynamic time warping (DTW)algorithm .The experimental results show our algorithm EI-DTW enhances the authentication accuracy by canceling the endpoint alignment restriction on gesture matching ,and improves the authentication efficiency by the early termination strategy and limiting the warp slope .关键词
