It should be noted that, in some embodiments of the present application, before step S102, the corresponding keyword smart contract needs to be written into the blockchain.
Intelligent contracts, also known as chaining codes (chaincodes), are an important concept in blockchain (blockchain) technology. The block chain is a distributed account book, is a decentralized database, needs to maintain all nodes in the block chain network collectively, and comprises a plurality of blocks (blocks), each block comprises a plurality of transaction records and also comprises a hash value of the previous block, so that all the blocks are connected in sequence to form the block chain. Smart contracts are event-driven, stateful, running on top of a replicated, shared ledger, and capable of managing data on the ledger. The intelligent contract looks like a piece of ordinary computer-executed program, and the code content of the intelligent contract specifies the rules and logic of the transaction.
S103, under the condition that the network article accords with the execution condition of the keyword intelligent contract, the keyword intelligent contract is executed on the network article, and the execution result information is written into the block chain.
In some embodiments of the present application, the keyword intelligence contracts are used to:
determining the number of keywords corresponding to preset sensitive information in the network article;
determining the sensitivity score of the network article according to the number of the keywords based on a preset rule;
the execution result information comprises sensitivity scores of the network articles.
The sensitivity evaluation can be carried out along with the network articles through the keyword intelligent contract, and the sensitivity evaluation of the network articles is written into the block chain and is difficult to tamper.
In some embodiments of the present application, the keyword intelligence contracts are used to:
determining keywords corresponding to preset sensitive information in the network article;
matching the keywords with replacement words in a replacement word database corresponding to preset sensitive information;
replacing the keywords in the network article according to the replacement words matched with the keywords to obtain a new network article;
the new network article does not include keywords corresponding to the preset sensitive information, and the execution result information includes the new network article.
Through the keyword intelligent contract, keywords corresponding to preset sensitive words can be replaced, a new network article without the keywords is generated, and the new network article is broadcasted.
And S104, writing the network article into the block chain under the condition that the network article does not accord with the intelligent keyword contract.
It should be noted that step S104 may be executed directly after step S102, and is not limited in the embodiment of the present application.
By the scheme, the keywords of the network articles are screened through the intelligent contracts deployed on the block chains, and corresponding execution result information can be obtained through the intelligent contracts. Whether the network articles comprise vocabularies with negative influences or not can be quickly screened, and the network articles with the negative influences can be correspondingly processed based on the intelligent contracts.
Based on the same idea, some embodiments of the present application further provide a device and a non-volatile computer storage medium corresponding to the above method.
