Abstract

The invention discloses a method and device for identifying a living body by opening a mouth based on face feature points, which are used for solving the problem that the accuracy of face recognition is influenced by a false face, so that the information security of a user is damaged. The method comprises: by adopting a face feature point detection algorithm, determining mouth feature points corresponding to a to-be-detected face; recording the position change of the mouth feature points in a preset time period, and calculating to obtain a corresponding change rule; and judging whether the change rule accords with a preset judgment rule or not, and determining whether the human face is a living body or not. According to the method, whether the face to be detected is a living body can be directly and effectively judged, the authenticity of identity authentication is ensured, the accuracy of identity authentication is improved, and illegal persons are prevented from disturbing the normal order of identity authentication by using false faces.

Description

technical field [0001] The present application relates to the technical field of living body recognition, and in particular to a method and device for recognizing a living body by opening a mouth based on facial feature points. Background technique [0002] With the development of science and technology, the scope of application of the Internet is becoming wider and wider. [0003] In the Internet age, users' personal information and personal privacy are more likely to be stolen. Therefore, the protection of users' personal information has also been strengthened. In the process of information protection, the user's rights to view information can be restricted through identity authentication. [0004] At present, when performing identity authentication, face recognition technology can be used to distinguish individual organisms through the biological characteristics of the organism itself, that is, facial features, so as to realize the identity authentication of users.
