Block-chain-based data rights protection method

The invention belongs to the technical field of data security, and specifically relates to a block-chain-based data rights protection method. The steps of method are as follows: a user owning data formulates data circulation strategies according to data rights that need protection, compiles the circulation strategies into an intelligent contract, and deploys the intelligent contract on a block chain system; and before other users perform data circulation, the user serving as a data transferee needs to use identity information and related data circulation attributes to call the intelligent contract, and the intelligent contract automatically provides an approval result of a circulation application according to the established data circulation strategies: if circulation is allowed, a dynamic circulation authorization code is returned to the transferee user; otherwise application failure is returned. The block-chain-based data rights protection method provided by the invention is an application of a block chain system, removes dependence on a third-party authority organization in a data rights protection process, ensures that the data circulation strategies formulated by the data owner are not maliciously modified, and a strategy execution result is not manually manipulated, thereby providing a just, transparent and credible execution environment for data circulation processes of data transactions, data opening and sharing and the like.

A digital resource infringement tracking method and system based on block chain digital watermarking

The invention relates to the technical field of block chain application. The invention discloses a block chain digital watermark-based digital resource infringement tracking method and system, and themethod comprises the steps: packaging digital resource uploading, transaction and distribution information into a block, and recording the block in a block chain according to a time sequence, and comprises the steps: generating a block on the block chain when a user uploads digital resources, and recording copyright information; when the copyright of the digital resource is transferred, a block is generated on the block chain, and corresponding transaction information is recorded; when the digital resources are distributed, a block is generated on the block chain, corresponding distribution information is recorded, and a digital watermark is embedded into the digital resource entity; when infringement copying of digital resources occurs on the market, infringement tracking is carried outby combining the digital watermarks in the infringement copying of the digital resources with the transaction records of the digital resources on the block chain system. According to the method, the digital watermark is combined with the block chain, so that the digital watermark information can not be tampered with a chain, and infringement tracking information is guaranteed to be real and credible.

A data security protection and sharing method based on block chain, a system and an application thereof

The invention belongs to the technical field of digital information transmission, and discloses a data security protection and sharing method based on block chain, a system and an application thereof.Each participant sends identity authentication information and a key. The summary information and hash value of the original data are packaged and uploaded to the block chain system. The packaging node packages all the summary information and hash values received in the time period into blocks according to a certain order and sends them to the consensus node. According to the RPBFT protocol, thewhole network broadcasts the consensus result after reaching the consensus efficiently; the block is recorded into the account book according to the consensus result; different access control protocols are associated with blocks. The user can access the account book after the authorization of the access control protocol, and obtain the data summary recorded in the account book and the original information storage location by using the quick retrieval function. The user accesses the original information storage database to obtain the original data. The invention can resist the tampering of themalicious node, realize the consensus efficiently, and remarkably improve the data retrieval efficiency.

Consensus building method based on lottery mechanism, block chain system and storage medium

The invention discloses a consensus building method based on a lottery mechanism, a block chain system and a storage medium. The method comprises the steps that an accounting node of a last block in ablock chain is determined, and a data packet is acquired on the basis of the accounting node of the last block, wherein the data packet at least comprises transaction data of a to-be-connected blockpreparing to be connected with the last block; Hash operation is conducted on the basis of the acquired data packet and node data saved in the node to obtain a first candidate Hash value; a second candidate Hash value broadcast by other nodes is acquired, and a target Hash value is selected from the first candidate Hash value and the second candidate Hash value according to a first preset rule, wherein the node of the target Hash value is the accounting node of the to-be-connected block. According to the consensus building method, it can be guaranteed that all nodes in the block chain competefor the accounting permission in complete equality, more people can be encouraged to participate in the block chain, and therefore the method is beneficial for application and popularization of the block chain.
