Abstract

Embodiments of the invention provide a living body detection method and device and electronic equipment. The method comprises the steps of extracting spatial features and time features of multiple frames of to-be-detected face images; inputting the spatial features and the time features into a first convolutional neural network model, and obtaining low-dimensional spatial features and low-dimensional time features output by a global pooling layer in the first convolutional neural network; inputting the multiple frames of face images into a second convolutional neural network model, and obtaining biological motion features output by a full connection layer in a second convolutional neural network; and calculating a living body detection result of the multiple frames of face images accordingto the low-dimensional spatial features, the low-dimensional time features and the biological motion features.

Description

technical field [0001] The embodiments of this specification relate to the field of Internet technology, and in particular, to a method and device for detecting a living body, and electronic equipment. Background technique [0002] With the continuous development of biometric technology, especially face recognition technology has been widely used; it greatly simplifies the process of identity authentication scenarios such as payment, access control, and security check. [0003] However, the face recognition system is vulnerable to attacks such as face photos and face videos. These attacks are called liveness attacks, and techniques for detecting liveness attacks are called liveness detection techniques. Contents of the invention [0004] A living body detection method and device and electronic equipment provided in the embodiments of this specification: [0005] According to the first aspect of the embodiments of this specification, there is provided a living body detect...
