Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] figure 1 It is a flow chart of the first embodiment of the method for identifying video tampering using blockchain in the present invention. like figure 1 As shown, in step S1, in the original video generation process, multiple original video hash values ​​are obtained and an original video Merkle tree is constructed based on the multiple original video hash values. In a preferred embodiment of the present invention, the video image of the original video can be collected every set time, for example, 1 second. And generate the original video hash value according to the relevant data of the...

Abstract

The invention relates to a method for identifying video tampering by using a blockchain, which comprises the following steps: S1, in an original video generation process, obtaining a plurality of original video hash values and constructing an original video Merkel tree based on the plurality of original video hash values; s2, writing the original video Merkel tree into a block chain; s3, generating a plurality of video hash values from the to-be-verified video according to the generation rule of the original video hash values, and constructing a video Merkel tree based on the plurality of video hash values; and S4, based on a comparison result of the original video Merkel tree and the video Merkel tree, judging whether the video is tampered or not. The invention also relates to a device for identifying video tampering by using the blockchain and a computer storage medium. According to the method and device for identifying video tampering by using the block chain and the computer storage medium, whether the video is tampered or not can be rapidly and effectively identified by using the block chain technology, and the security of the video is improved.

Description

technical field [0001] The present invention relates to the field of video identification, and more specifically, to a method, device and computer storage medium for identifying video tampering using blockchain. Background technique [0002] Blockchain is a new application model of computer technologies such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. Through the hierarchical structure of the scattered network connected by nodes, the blockchain can realize the comprehensive transmission of information in the entire network, and can verify the accuracy of the information, so it is widely used in various fields. [0003] With the rapid development of digital multimedia technology, video plays an increasingly important role in all aspects of social life, especially in the monitoring field. Video is increasingly playing a role in public safety because of its highly consistent reproduction of past events. However, sin...
