Fraud possibility analysis method and device and storage medium

Abstract

The invention provides a fraud possibility analysis method and device and a computer readable storage medium. The method comprises the following steps that sample videos are collected and the fraud marks are allocated to the sample videos; the image features and the audio features of each sample video are extracted, and the video features of each sample video are obtained through combination; a neural network is constructed according to the sequence length of the sample videos and the dimension of the video features; the neural network is trained by using the video features and the fraud markof each sample video and the training parameters are optimized so that a fraud possibility analysis model is obtained; the preset duration of facial video of an object to be analyzed is acquired; theimage features and the audio features of the video are extracted so as to obtain the video features of the video through combination; and the video features are inputted to the fraud possibility analysis model, the fraud probability and the no-fraud probability of the object to be analyzed are outputted and the output result of the highest probability value is taken as the fraud possibility analysis result of the object to be analyzed. Whether the character is suspected of fraud can be objectively judged by using the fraud possibility analysis method and device.

Description

technical field [0001] The present invention relates to the technical field of information processing, in particular to a fraud possibility analysis method, device and storage medium. Background technique [0002] At present, character fraud analysis is generally carried out through face-to-face interviews, which is extremely dependent on the experience and judgment of analysts, and consumes a lot of time and manpower, and the analysis results are often inaccurate and objective. There are also professional instruments and equipment to judge whether a fraud suspect has committed fraud by detecting indicators such as breathing, pulse, and skin electricity. However, such instruments and equipment are usually expensive and easily constitute human rights violations. Contents of the invention [0003] In view of the above reasons, it is necessary to provide a fraud possibility analysis method, device and storage medium, which can objectively and accurately judge whether a person...
