[0043] In order to make the purpose, technical scheme and advantages of the present specification clearer, the technical scheme of the present application will be described in detail below in combination with the specific embodiments of the present specification and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments. Based on the embodiments in the specification, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0044] The technical scheme provided by the embodiments of the present application will be described in detail below in combination with the drawings.

[0045] Embodiments of the present application provide a method for processing rumors on a network based on a blockchain and a corresponding solution. Based on the decentralized nature of the blockchain, the information dissemination process on the platform is transparent and visible. Through digital signature and timestamp technology, the information on the platform is queryable and traceable.

[0046] Figure 1 A method flowchart is provided for embodiments of the present specification. As shown in the figure, the method comprises:

[0047] S101 receiving first information published by a user, calculating the reliability of the first information through an algorithm;

[0048] S102 adding a digital signature to the first information according to the reliability of the first information, and publishing the first information on an information platform;

[0049] S103 writing the digital signature of the first information into the blockchain to trace the user who published the first information.

[0050] A blockchain is a chain-like data structure that combines data blocks in a sequential manner according to time sequence, and uses cryptography to ensure that it is tamper-proof and unforgeable. Although the underlying technology of the blockchain has been developed for many years, it cannot be effectively applied in specific scenarios.

[0051] According to specific embodiments of the present application, in step S101, a smart contract for processing the first information is set up on the blockchain. The smart contract is an automatically running script deployed on the blockchain. Since it is set up on the blockchain, it has the characteristics of being open and transparent. Users can set rules in advance through the smart contract to write data to the blockchain and obtain data browsing permissions, which largely avoids the disclosure of private information. Of course, the smart contract is not the only implementation of the present application, and it is set up according to different blockchain platforms, such as Ethereum, Hyperledger, etc.

[0052] According to specific embodiments of the present application, the nodes of the blockchain are not particularly limited in the embodiments of the present application and can include nodes constructed by the information exchange platform itself or nodes constructed by government regulatory departments.

[0053] According to a specific embodiment of the present application, in step S102, the smart contract calls the relevant algorithm to calculate the reliability of the first information. Specifically, the relevant shielded words or sensitive words can be pre-set, and it is determined whether the first information contains shielded words. If the shielded words are contained, the user is notified to modify the first information. It is determined whether the first information contains sensitive words. If the sensitive words are contained, the smart contract calls the semantic processing logic to perform semantic processing on the first information to identify the meaning of the first information. Specifically, the semantic processing logic can be an artificial intelligence neural network algorithm based on semantic recognition. The neural network algorithm can be stored in the blockchain or stored in an off-chain manner.

[0054] The blockchain and off-chain storage are in a symbiotic relationship. For some data, the high-value and key data part exists on the chain, and the low-value and large-volume part exists on the off-chain storage. The two are associated together using a unique identifier. The off-chain storage can save plaintext data or encrypted data. The off-chain encrypted storage stores the data in the off-chain storage after encryption, and the key is managed by the blockchain. To decrypt the data in the storage, authorization must be applied to the blockchain. After authorization, the decryption key can be obtained, and then the data in the off-chain encrypted storage can be decrypted.

[0055] Further, the smart contract records the number and frequency of times that the user is notified to modify the first information published by the user, and then calculates the first credit of the user according to the number and frequency of times that the user is notified to modify the first information published by the user.

[0056] Further, in order to ensure the reliability of the first information, the second credit of the user is obtained from a relevant credit platform. The credit platform can be a credit platform constructed by a non-governmental organization, a credit platform constructed by a bank or other financial institution, or a credit platform established by a court or other law enforcement agency. It can be understood that the credit of the present application can also be referred to as confidence. The algorithm used can be a Bayesian algorithm or other algorithms, and the present application does not particularly limit this.

[0057] According to a specific embodiment of the present application, in step S102, after the digital signature is added to the first information according to the reliability of the first information, and the first information is published on the information platform, the method further comprises: receiving the number of views, the number of comments and the number of forwards of the first information on the information platform; and determining whether to write the first information into the blockchain according to the number of views, the number of comments and the number of forwards.

[0058] Specifically, when the number of views, the number of comments and the number of forwards of the first information on the information platform all reach a preset number, the first information has attracted widespread attention, at this time, if the reliability of the first information is calculated by an algorithm to be much greater than a threshold value of information publishing on the information platform, specifically, for example, the threshold value is one hundred, and the reliability less than one hundred cannot be published on the platform. If the reliability value of the first information is one hundred and fifty, the first information does not need to be written into the blockchain, if the reliability value of the first information is between one hundred and one hundred and thirty, the first information is written into the blockchain. If it is found later that the first information is a rumor, the first information stored in the blockchain can be used as evidence.

[0059] According to a specific embodiment of the present application, the adding of the digital signature to the first information comprises marking the first information with a hash value calculated by using a hash function. Alternatively, the digital signature of the first information published by the user is generated by using a private key of the user. It can be understood that the user and the digital signature are associated with each other and correspond in meaning.

[0060] In some preferred embodiments of the present application, the method further comprises packaging the digital signature and the timestamp into a block and writing the block into the blockchain. Correspondingly, the blockchain receives an information query request, which can be proposed by a user or by a government regulatory agency, and determines the user who publishes the first information according to the digital signature and the timestamp.

[0061] Based on the same idea, some embodiments of the present application also provide a device and a non-volatile computer storage medium corresponding to the above-mentioned method.

[0067] add a digital signature to the first information according to the reliability of the first information, and publish the first information on an information platform;

[0068] write the digital signature of the first information into the blockchain to trace the user publishing the first information.

[0069] Some embodiments of the present application provide a non-transitory computer storage medium for processing rumors in a blockchain-based network, storing computer executable instructions, the computer executable instructions being arranged to: Figure 1
