Abstract

The invention provides an IP video tamper-proofing monitoring method and system. The method comprises the following steps: acquiring signal source information between a signal source platform and a service platform and first video source information between the service platform and a metropolitan area network; respectively carrying out feature extraction on the signal source information and the first video source information to obtain first effective frame information and second effective frame information; respectively processing the first effective frame information and the second effectiveframe information through a hash algorithm to obtain a plurality of first characteristic values and a plurality of second characteristic values, and taking the plurality of first characteristic valuesas reference characteristic values; matching the plurality of second characteristic values with the reference characteristic value; if the first matching result reaches the preset matching rate, determining that the first video source information is not tampered; and if the first matching result does not reach the preset matching rate, determining that the first video source information is tampered. The source video does not need to be modified, and the video source information of each link can be effectively monitored by adopting a distributed deployment mode.

Description

technical field [0001] The invention relates to the technical field of video processing, in particular to an IP video tamper-proof monitoring method and system. Background technique [0002] At present, there are two main methods for video anti-tampering monitoring. The first method is to add watermark to the source video during the production process. Whether the watermarks are the same, and if they are the same, it means that they have not been tampered with; this method performs anti-tampering monitoring on the source video by adding watermarks, but there is a certain degree of modification to the source video. [0003] The second way is to extract the pixel domain and frequency domain features of the video signal in the source link, and extract the pixel domain and frequency domain features of the video signal in the broadcast link, and combine the pixel domain and frequency domain features of the video signal in the source link with the broadcast The pixel domain and f...
