| description | The invention provides a security analysis method and device for a recorded video. The method comprises the following steps: separating the recorded video into an audio file and an image file; judging whether corresponding human voice and background voice in the human voice file and the background voice file in the audio file are credible or not, and recording uncredible labels; extracting character information in the human voice, outputting a text file, and judging whether the text file contains a specified instruction and a corresponding label for limiting vocabulary recording or not; analyzing character objects in the image file by using a target detection technology and recording labels; performing audio and video comprehensive analysis on the recorded video, and recording an abnormal behavior label; and summarizing various labels, and carrying out risk prompting after obtaining risk scores of the summarized labels based on the weights of different labels. On one hand, the security of the recorded video c |
