Method and device for generating verification content of lip language recognition and related device

Abstract

The embodiment of the invention discloses a method and device for generating the verification content of lip language recognition. The method and device are suitable for recognizing facial actions inin-vivo body detection. The method includes the steps that a lip language recognition request of a terminal device is acquired, verification request parameters are obtained according to the lip language recognition request, and the number of verification objects needed by lip language recognition verification is determined; recognition objects are selected from a plurality of preset recognition object groups to serve as the verification objects for forming the verification content of lip language recognition, wherein the adjacent verification objects in the verification content belong to different recognition object groups respectively; the verification content is output to a verification interface for lip language recognition, a user of the terminal device is subjected to lip language recognition verification of the verification content. By the adoption of the method and device, the verification content that the adjacent verification objects are different in pronunciation lip shape change can be generated, and the occurrence probability that the lip shape changes are difficult to recognize is reduced, so that the accuracy and convenience of lip language recognition are improved.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a lip recognition verification content generation method and a related device. Background technique [0002] At present, customers' needs for remote identity verification are gradually emerging, and using face recognition to authenticate customers has become one of the common means of remote identity verification. In the process of face recognition, in order to carry out anti-fraud recognition, on the basis of video verification, live detection strategies such as blinking, shaking head, random number and / or text lip reading inspection are added. Among them, although the lip language recognition used in the lip-reading inspection of random numbers and / or texts detects lip movements, this process is still dominated by speech recognition, supplemented by lip movement matching. In the existing technology, lip language recognition is to recognize the face from the image dir...

Problems solved by technology

Lip recognition in the prior art mainly relies on the support of contextual semantics to obtain the most likely matching results. When a large number of Chinese and / or digital words have a high degree of mouth shape overlap, simple lip recognition is difficult
