Monitoring video leakage tracing method based on random watermark, and storage medium

Abstract

The invention relates to a monitoring video leakage tracing method based on a random watermark, and a storage medium. The method comprises the following steps of, after a background server receives arequest sent by a user terminal, acquiring user information, equipment information and information of a needed monitoring video; carrying out uniqueness processing on the obtained information; acquiring a video playing request initiated by the user terminal and the uniqueness information by a streaming media server; acquiring a random watermark method from the background server; and carrying out random watermark processing on a needed monitoring video stream according to the random watermark method. The tracing method is different from the prior art; and the uniqueness processing is carried out on the needed monitoring video, and targeted watermarking (a random frame, a random number, a random direction, a random position, a random size and a random font) is carried out for the video played by each user terminal, so that the watermark of the played video is not removed, the video leakage can be traced, and the source of video leakage can be traced subsequently.

Description

technical field [0001] The invention relates to the technical field of video leakage traceability methods, in particular to a random watermark-based surveillance video leakage traceability method and a storage medium. Background technique [0002] With the continuous development of technology, video surveillance has become popular in various enterprises. With the rapid development of information technology, the requirements for the protection of confidential information and privacy of video surveillance are becoming more and more obvious, and there are many channels for the leakage of video files, including Capture, bootleg recording, etc., and after the video is leaked, the source of the leak cannot be traced correctly, resulting in the source of the leak being unable to be plugged and remedied in time. [0003] At present, the widely used watermarking technology is mainly completed on the user client, such as video barrage, but this kind of watermarking cannot prevent vide...

AI Technical Summary

Problems solved by technology

[0005] 1. The watermarking technology is completed through the client, which cannot guarantee the security of the transmission process, resulting in the leakage of non-watermarked videos

[0006] 2. The surveillance camera is watermarked, and the user information that needs to be played cannot be obtained. The watermark is fixed and single, and the source of the leak cannot be traced correctly.

[0007] 3. For the video streams that need to be monitored, if all watermarks are added at the source of the video, the user experience will not be very good; if watermarks are added according to user needs, the performance requirements of the server will be high, resulting in increased monitoring costs

After the video is stolen, it is impossible to effectively trace the source of the video leak
