Face recognition based method for authenticating identity

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...

Problems solved by technology

The disadvantage of this method is that the amount of image data transmitted by face authentication is large, and the calculation amount of face recognition calculation is also very large, so the performance requirements of the processing equipment are relatively high.

The disadvantage of this method is that the angle and size of the face cannot be controlled during image acquisition, and the collected face information needs to be processed and corrected, which increases the amount of calculation and processing difficulty
