Embodiment Construction

[0033] Specific embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be understood that the specific embodiments described here are only used to illustrate and explain the present invention, and are not intended to limit the present invention.

[0034] The video-on-demand method provided by this embodiment is based on the block chain technology. The video server provides the program content, and the initial global identification of the program content is spliced ​​with the initial block identification of the video block, and then the signature is uploaded to the block chain. The broadcast control node is used to verify the program content provided by the video server. After verification, the initial global identification of the program content is signed with a private key and uploaded to the blockchain. The broadcast control node is also used to provide digital certificates to video servers and playback...

Abstract

The invention discloses a video-on-demand method and system based on a block chain. The video-on-demand method is applied to a playing terminal, and comprises the following steps: receiving program content from a video server, and obtaining an initial global identifier of the program content; wherein the initial global identifier is a unique identifier which is stored in a block chain by the videoserver and is used for identifying the program content and is obtained according to metadata of the program content; judging whether the initial global identifier is signed by a broadcast control node or not; if the initial global identifier does not have the signature of the broadcast control node, forbidding playing the program content; and if the initial global identifier has the signature ofthe broadcast control node, playing the program content. According to the video-on-demand method, tampered program content is prevented from being played, and subsequent investigation and evidence collection can be facilitated.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a blockchain-based video-on-demand method and system. Background technique [0002] With the popularization of mobile terminals, the video-on-demand service is deeply loved by the public. At present, video programs are played based on IP networks. When devices such as video servers (including CDN) are cracked, the content of video programs can be easily modified. When an additional device is connected to the network device (such as a switch) for transmitting video programs, it is easy to intercept and replace the normal video code stream. In other words, when playing video programs based on IP networks, the contents of video programs are easily tampered with maliciously, causing irreparable losses to content providers and operators. [0003] In addition, after the tampered video program is broadcast, the content provider who maliciously plays the illegal content ...
