Identity authentication method based on dynamic gesture

Abstract

The invention discloses an identity authentication method based on a dynamic gesture. According to the method, an intelligent cell phone acceleration sensor is utilized to obtain dynamic information when the gesture is executed, and matching authentication is conducted on the dynamic information of the gesture through a DTW efficient method combining relaxation of end point limitation and early termination. By means of the DTW efficient method combining relaxation of end point limitation and early termination, the problem of authentication failure caused by unaligned end points between gesture sequences is solved by relaxing end point limitation of a matched path, meanwhile calculating amount is reduced by utilizing bending slope limitation and an early termination strategy, and a test shows that the method has a good result in the aspects of precision and efficiency of identity authentication.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition and identity authentication, and relates to a dynamic gesture identity authentication method based on an android platform. Background technique [0002] Identity authentication is the process by which the system confirms whether the real identity of the operator is consistent with the claimed identity. With the popularity of mobile phones today, user identity authentication on mobile phones has also become an important part of information security. At present, mobile phone identity authentication is mainly divided into password-based identity authentication and biometric-based identity authentication. Commonly used password-based identity authentication includes user password method and Jiugongge unlock method. The common feature of password-based identity authentication is that the password is easy to leak, and the password is frequently changed for the security of the password, which...

Problems solved by technology

At present, there are basically no devices that can obtain fingerprints on mobile phones. If fingerprint authentication is used, an external device is required, which is inconvenient to use; and iris authentication requires a high camera, so the minimum price of the camera is 7,000 US dollars, and it is difficult for mobile phones. Online signature Authentication also requires external equipment; in addition, the collection equipment for vein authentication also has special requirements, the design is complex, the manufacturing cost is high, the product is difficult to miniaturize, and it is not suitable for portability

Secondly, there are some limitations of the authentication method itself.

The iris authentication method is extremely difficult to read the characteristics of black eyes. Face authentication and voice authentication are very easily affected by the outside world or even oneself. Offline signature authentication is easy to be stolen and transferred
