Embodiment Construction

[0028] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0029] An identity authentication method based on face recognition mainly includes two parts: the face recognition verification feature extraction for the verified person, and the use of the extracted feature data to verify whether the identity of the registered person is legal.

[0030] Such as figure 1 As shown, a face recognition verification feature extraction method in identity authentication based on face recognition, comprising the following steps:

[0031] F11: The face image of the verified person is acquired by the video acquisition terminal.

[0032] The specific implementation steps are: first input the information of the person being verified, so that the corresponding verification information can be indexed. The face image is obtained from a video capture device, and the video device is a commonly used video device, such as a ca...

Abstract

The invention relates to a face recognition based method for authenticating identity. In the method, recognition characteristic data and a corresponding recognition characteristic region are extracted through face recognition; a drawn portrait painting is generated by a face image; an authenticated person is prompted to adjust the distance and angle with an image acquisition device by the portrait painting when the face image is acquired; when the acquired image is aligned with the portrait painting, a terminal extracts the recognition characteristic region and calculates the recognition characteristic data; and the recognition characteristic data are associated with the saved corresponding recognition characteristic data to authenticate user identity. The method can greatly reduce the calculated amount and the data communication amount of face recognition, and is particularly applicable to identity authentication application of mobile terminal equipment.

Description

technical field [0001] The invention belongs to the field of information security, and in particular relates to an identity authentication method based on face recognition. Background technique [0002] As a common identity authentication method, face recognition is widely used in various identity authentication occasions because it only needs to be equipped with a camera and has low requirements for device peripherals. However, face recognition relies on complex image recognition and image processing, and the amount of calculation is often huge. It requires high equipment for recognition and calculation, and its application is limited. For example, PDAs with limited computing power and limited communication data cannot be used. on the mobile terminal device. [0003] Such as the Chinese patent application whose application number is 200610117905.2--network login system and login method with face authentication, this method first stores the feature information including fac...
