Shared content supervision method based on threshold key sharing and block chain

Abstract

The invention discloses a shared content supervision method based on threshold key sharing and a block chain. The entity involved in the invention comprises a supervision department, a content provider, a block chain and a miner. The method specifically comprises the following steps: step 1, content permission snapshot; step 2, secret key distribution and recovery based on Shamir (t, n); step 3, content review based on transactions. according to the method and the system, the Shamir (t, n) threshold secret sharing is utilized, so that multiple parties can participate in content review together, the accuracy and fairness of content review executed by a supervision department are ensured, and collusion in the supervision department is effectively prevented. Besides, the whole review process is carried out in a block chain transaction mode, so that the defect of content supervision in a content sharing scheme based on a block chain at present is overcome, absolute disclosure and accuracy of the review records are ensured, and the public can conveniently audit and check the review records.

Description

technical field [0001] The invention relates to the field of content supervision, in particular to a shared content supervision method based on threshold key sharing and blockchain. [0002] technical background [0003] Although the current content sharing based on blockchain technology ensures the security of shared content and the privacy of users, it also introduces some problems: 1) traditional copyright infringement issues are more difficult to find; 2) malicious users take advantage of anonymity, etc. 3) Malicious users publish illegal content: for example, it is more convenient to conduct network rumors, spam and malicious codes. At present, content monitoring technologies in the Internet can be roughly divided into: network blocking and content analysis. [0004] However, due to the particularity of the blockchain network structure, the traditional IP-centric network blocking technology for content supervision has lost its reference value; and the blockchain-based c...

Problems solved by technology

[0003] Although the current content sharing based on blockchain technology ensures the security of shared content and the privacy of users, it also introduces some problems: 1) traditional copyright infringement issues are more difficult to find; 2) malicious users take advantage of anonymity, etc. It is more convenient to carry out network attacks (such as spreading network viruses); 3) Malicious users publish illegal content: for example, network rumors, spam and malicious codes are more convenient

[0004] However, due to the particularity of the blockchain network structure, the traditional IP-centric network blocking technology for content supervision has lost its reference value; and the blockchain-based content sharing schemes all implement encrypted transmission, which makes Existing content analysis techniques are nearly ineffective
