Video anti-counterfeiting system, method and device

Abstract

The invention provides a video anti-counterfeiting system, a method and a device, which relate to the technical field of data processing. The system comprises a first node, at least one second node and a third node. Wherein the first node is used for acquiring a video stream and segmenting the video stream; generating a first check value for the N video streams obtained after the segmentation; selecting a second node for receiving and recording an i-th video stream and a corresponding first check value; the third node generates a second check value corresponding to the ith video stream; When it is detected that the first check value corresponding to the ith video stream is inconsistent with the second check value corresponding to the ith video stream, it is determined that the ith video stream obtained from the jth selected second node is tampered with. The present application judges the authenticity of a video by a check value, thereby alleviating the problem of tedious steps in videoauthenticity identification in the prior art.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular, to a video anti-counterfeiting system, method and device. Background technique [0002] With the development of network technology, the security of stored information has attracted more and more attention. Although various data (pictures, videos, music, etc.) can be conveniently stored through the Internet, the security of these data still needs to be guaranteed by these third parties. , The Internet itself does not have a value protection mechanism, and if the information that needs to be kept secret is leaked and then tampered with, the security and authenticity of this information cannot be guaranteed. [0003] Recently, with the popularization of digital video recording equipment, the reduction of storage costs and the growing strength of editing software, digital video is gradually becoming an important means for people to store information. However, the ...

Problems solved by technology

[0002] With the development of network technology, the security of stored information has attracted more and more attention. Although various data (pictures, videos, music, etc.) can be conveniently stored through the Internet, the security of these data still needs to be guaranteed by these third parties. , the Internet itself does not have a value protection mechanism, and if the information that needs to be kept secret is leaked and then tampered with, it will be even more impossible to guarantee the security and authenticity of the information

[0003] Recently, with the popularization of digital video recording equipment, the reduction of storage costs and the growing strength of editing software, digital video is gradually becoming an important means for people to store information. However, the authenticity of video information is determined by judging the The information is compared to determine whether the frame video has changed, and the steps are relatively cumbersome

[0004] However, in actual operation, most video tampering detection algorithms can only detect one tampering method. When multiple tampering methods tamper with information, the authenticity cannot be detected at one time, which makes the steps of video authenticity identification more cumbersome.
