User online authentication device

Abstract

The invention provides a user online authentication device. The device comprises a user registration module, a user authentication module, an in-vivo detection unit, an image processing unit, a feature extraction unit, a comparison unit and a result processing unit, wherein the user registration module is used for a user to fill in information on line and is also used for acquiring a facial imageof the user, extracting facial feature data and establishing a user facial feature database; the user authentication module comprises an information acquisition unit and is used for collecting the user facial image; the in-vivo detection unit is used for confirming whether a face in the collected user facial image is living; the image processing unit is used for preprocessing the collected facialimage; the feature extraction unit is used for processing the preprocessed facial image and extracting the facial feature data; the comparison unit is used for comparing the extracted facial feature data with facial feature data in the user facial feature database and outputting a matching result; and the result processing unit is used for doing corresponding processing according to the comparisonresult. Through the device, the situation that a face-containing photo is adopted to cheat authentication can be effectively avoided, and the security performance is high.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a user online authentication device. 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] When the user performs online authentication, it is necessary to collect the user's face image, then perform face detection, image processing, and face feature extraction, and compare the extracted face features with the corresponding face features in the feature database. Obtain the authentication resu...

Problems solved by technology

[0003] When the user performs online authentication, it is necessary to collect the user's face image, then perform face detection, image processing, and face feature extraction, and compare the extracted face features with the corresponding face features in the feature database. Obtain the authentication result; However, there are following deficiencies in the authentication device in the prior art: the traditional user identity authentication device based on collecting the user's face cannot identify whether the user's face is a photo or a real person when collecting the user's image
