Telekinetic-dynamic-gesture-based user identity authentication method and apparatus

Abstract

The invention, which belongs to the technical field of mode recognition and identity authentication, discloses a telekinetic-dynamic-gesture-based user identity authentication method and apparatus that are used for non-contact rapid user identity authentication. According to the invention, single-dynamic-gesture-based video collection and pretreatment are carried out on an authenticated person; a super matching template is synthesized to obtain a matching value of a DTW; authentication determination is carried out on the matching value and, to be specific, a collected dynamic gesture is compared with template obtained by all authentication people previously; if an offset value is higher than a standard threshold value, the user is prompted to be an unauthorized user; and if the offset value is lower than the standard threshold value, comparison with a set threshold value is carried out continuously; if the offset value is lower than the set threshold value, the user authentication is determined to be successful; and if the offset value is higher than the set threshold value, the user authentication is determined to be unsuccessful. On the basis of the non-contact telekinetic type user authentication way, the method and apparatus have wide application prospects in fields of secure verification, medical dust prevention, and secure game logging in and the like.

Description

technical field [0001] The invention belongs to the technical field of pattern recognition and identity authentication, and more specifically relates to a Kinect sensor-based Kinect sensor-based dynamic gesture user identity authentication method and device. Background technique [0002] Identity authentication is the process by which the identity security identification system confirms whether the operator's real identity is consistent with his declared identity. That is, all legal user information must be entered in advance. Then enter the testing stage. When a new user enters the system, he needs to declare his identity first, and then perform authentication matching. If the matching result shows that he does not belong to the declared user, it will prompt "this user is an intrusion user". [0003] At present, the main methods of identity authentication are based on user name / password, IC card authentication, dynamic password, traditional biometrics, etc. Identity authe...

Problems solved by technology

[0008] The purpose of the present invention is to overcome the security risks and cumbersome deficiencies of the traditional biometric-based identification technology, and provide a dynamic gesture user identity authentication method and device; the present invention uses Kinect to collect the trajectory of dynamic gesture movements in the air information and complete the identity authentication, using the synthetic super matching template and the DTW efficient algorithm for averaging the matching results, first preprocessing the test data samples, making 3 super matching templates for each dynamic gesture, and combining these 3 super matching The average value of the DTW matching results between the template and the test sample is used as the final matching result of the gesture. The present invention can effectively improve the accuracy of identity authentication and obtain an ideal identity authentication effect.
