Problems solved by technology

However, with the wide application of face recognition technology, various methods have appeared to pretend to be living faces to pass identity verification, such as deceptive identification through photos, videos, etc. to pass identity verification; in order to prevent more and more diverse and more Deceptive attack methods, the more complex the live face recognition algorithm in the identity verification system, the larger the generated application capacity will be
However, the storage space of the mobile terminal client is limited so that it cannot accommodate a larger living body verification algorithm; at the same time, the processing power of the processor is weak, which makes the data processing time longer, which greatly limits the live face verification system on the mobile terminal.

Embodiment approach

[0120] As an implementation manner, the determining a plurality of matching feature points based on the first offset parameter corresponding to each feature point in the second group of N feature points includes: based on the second group of N feature points The first offset parameter corresponding to each feature point determines the target feature point corresponding to each feature point, and obtains the third coordinate of the target feature point; determines the corresponding target feature point in the first frame image The corresponding initial feature point; the fourth coordinate of the initial feature point is the same as the third coordinate of the target feature point; obtain the fourth offset parameter between the initial feature point and the target feature point; when When the fourth offset parameter reaches a preset threshold, determine that the target feature point is a matching feature point; when the fourth offset parameter does not reach the preset threshold,...

Abstract

The embodiment of the invention discloses a living body verification method and equipment. The method includes: obtaining image data based on an action instruction, analyzing the image data, and identifying an area in the image data that represents the location of a human face; Change, track the region; extract the texture features in the region; calculate the parameters representing the gesture based on the texture features; determine the action based on the parameters; when the action matches the action corresponding to the action instruction, determine Liveness verification passed.

Description

technical field [0001] The invention relates to face recognition technology, in particular to a living body verification method and equipment. Background technique [0002] At present, more and more identity verification systems use face recognition technology to authenticate user identities. Especially with the popularity of mobile terminal clients, more and more face verification systems have become the mainstream instead of traditional password verification. However, with the wide application of face recognition technology, various methods have appeared to pretend to be living faces to pass identity verification, such as deceptive identification through photos, videos, etc. to pass identity verification; in order to prevent more and more diverse and more Deceptive attack methods, the more complicated the live face recognition algorithm in the identity verification system, the larger the generated application capacity will be. However, the storage space of the mobile ter...
