Abstract

The invention discloses a method of liveness detection and a related device. The method comprises the following steps: acquiring an rPPG signal of at least one complete period from an image containinga skin area, acquiring an rPPG waveform characteristic from the rPPG signal, and judging whether a living body exists in the image or not according to the rPPG waveform characteristic. The computingdevice comprises a processing unit used for executing a program code, and a storage unit connected with the processing unit and used for storing the program code. The program code instructs the processing unit to execute the method. A living body detection device comprises a signal acquisition unit used for receiving an image containing a skin area and acquiring an rPPG signal of at least one complete period from the image; a waveform characteristic acquisition unit which is used for acquiring an rPPG waveform characteristic according to the rPPG signal; and a judging unit which is used for judging whether a living body exists in the image according to the rPPG waveform characteristics.

Description

technical field [0001] The invention relates to a living body detection method, in particular to a method and a related device for identifying whether skin in an image is a living body or a false image by means of a remote photoplethysmography method. Background technique [0002] The traditional mechanism for realizing liveness detection includes using the color texture, image reflection coefficient, and image depth information in the image to prevent people from deceiving the face recognition system by printing paper, photos, videos, or 3D masks. However, these mechanisms cannot effectively identify high-quality or high-resolution spoofs. There is also a mechanism that requires the person to be recognized to make an active response such as blinking or opening the mouth. However, this method of requiring the person to be recognized to make an active response often results in poor user experience. [0003] There is also a mechanism of using physiological signals to realize ...
