Embodiment 1

[0070] see figure 1 , the present invention discloses a user online authentication method based on living body detection and face recognition, said method comprising:

[0071] [Step S10] User online registration step: the user fills in the information online, and retrieves the corresponding second-generation ID card photo through the public security intranet according to the submitted ID number, extracts the face feature value of the photo, and establishes the user face feature value database.

[0072] [Step S20] Steps of online user authentication (for example, login authentication); including biopsy detection steps, image processing steps, feature value extraction steps, face comparison steps, and result processing steps. Specifically include:

[0073] -Step S21, the living body detection step, confirm whether it is a living body and obtain the optimal face photo; first generate a video of the ball movement on the setting screen, and record the trajectory of the ball moveme...

Abstract

The invention discloses a user online authentication method and system based on living body detection and face recognition. The method includes the user online registration step and the user online authentication step. The user online authentication step comprises the living body detection step, the image processing step, the feature value extraction step, the face comparison step and the result processing step. In the living body detection step, whether an authenticated user is a living body or not is determined and a face picture is acquired. In the image processing step, the collected face picture is processed. In the feature value extraction step, face part features of the processed face picture are extracted. In the face comparison step, extracted feature data of the collected face image are compared with corresponding face data in a user face feature value database, a threshold value is set, and when similarity exceeds the threshold value, the acquired result through matching is output. The user online authentication method and system can avoid authentication cheating through videos including faces, safety of the system is improved, recognition time can be shortened, and recognition accuracy is improved.

Description

technical field [0001] The invention belongs to the technical field of computer and face recognition, and relates to an online authentication and recognition method, in particular to an online user authentication method based on living body detection and face recognition; meanwhile, the invention also relates to a method based on living body detection and face recognition. Identifies the user in the online authentication system. Background technique [0002] In today's information society, information technology represented by computers and networks has penetrated into almost every aspect of life. However, while we enjoy "information", it also brings a shadow of insecurity to people. Therefore, people often need to authenticate their personal identities when they are engaged in various activities, so as to ensure the security of information. Because of the naturalness, stability, and ease of collection of human faces, it is used in identity authentication. [0003] Please ...
