Embodiment Construction

[0034] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] A video anti-tampering detection method, comprising the steps of:

[0036] (1) Video source input

[0037] Input the address of the video source to be monitored and the target video into the system. The video source is the original video without tampering, which is used as a comparison source; the target video is the video suspected of being tampered with, and is used to monitor whether the content of the video has been tampered with;

Abstract

The invention provides a video tamper-proofing detection method and a video tamper-proofing detection system. The video tamper-proofing detection method comprises the following steps: inputting a video source; de-encapsulating a video source, extracting key frames from all decoded video frame data, and extracting a grayscale image in the video frame data according to a color format of the image; cutting the grayscale image into n * n uniform blocks, performing feature value extraction on each block, and combining the obtained n * n feature values into a large feature value, namely the feature value of the frame of image; obtaining an original video feature value library and an object video feature value library, taking out feature values in the object video feature value library one by one, and comparing the feature values with the feature value library of the original video; if the frame is tampered through calculation, recording and storing the video from the frame until the video frame is not tampered through calculation or the video is finished, ending the recording and storage of the video, and taking the video as evidence for proving video tampering in the later period.

Description

technical field [0001] The invention relates to a video processing method, in particular to a video anti-tampering detection method and a video anti-tampering detection system, belonging to the technical field of video monitoring. Background technique [0002] In the field of video playback, after the video content of the video source manufacturer is provided externally, there is often no effective ownership protection. After the CDN manufacturer uses the video provided by the video provider, it often performs operations such as small-scale video insertion or modification, for example, Interstitials and more. Especially in the field of IPTV, after operators get live video sources from relevant radio and television departments, they often use their own CDN to conduct advertisement insertion and other operations, and then distribute them to users for profit. This is not in line with SARFT's policy. However, due to a series of factors such as the huge storage usage of the liv...
