The following are detailed below. The order of the following examples is not intended to limit the preferred order of the examples.

In an embodiment, referring to fig. 2a, describing the perspective of the apparatus, the first dummy information management apparatus may be specifically integrated in the first node of the blockchain.

101. And acquiring the information to be managed based on the false information.

In an embodiment, the first node may be a verification node, the information to be managed includes an information verification result, and the obtaining of the information to be managed based on the false information may include:

The checking node can be a server of a checking mechanism, the checking node is connected with the terminal through a network, and staff of the checking mechanism can send checking contents to the checking node through the terminal.

Among them, an information-checking contract is a Smart contract (Smart contract), which is a computer protocol intended to propagate, verify or execute contracts in an informative manner, which allows trusted transactions to be conducted without a third party, which transactions are traceable and irreversible. In the embodiment of the application, the information checking contract is an intelligent contract which checks certain false information.

The block chain can comprise a plurality of checking nodes, the status of each checking node is equal, and each checking node can directly and quickly acquire an information checking contract through the block chain, so that the enthusiasm of a checking structure can be mobilized, and a checking request initiated by a checking user can be quickly responded.

The staff of the checking organization can check the false information stipulated in the information checking contract and generate the checking content, the checking result is input into the terminal, and the checking content is sent to the checking node through the terminal.

In one embodiment, referring to fig. 5d, the verification node may perform semantic recognition, segment extraction, and classification on the verification content to obtain information such as the abstract, the label, and the category of the verification content. Wherein the category is consistent with the category of the false information corresponding to the verified content. The tags also include keywords of spurious information. In this embodiment, the categories may include medical health category, video security category, social, scientific, and other categories, and the like.

Among them, semantic recognition, segment extraction and classification involve NLP technology, where NLP (natural language processing) is an important direction in the fields of computer science and artificial intelligence. It studies various theories and methods that enable efficient communication between humans and computers using natural language. Natural language processing is a science integrating linguistics, computer science and mathematics. Therefore, the research in this field will involve natural language, i.e. the language that people use everyday, so it is closely related to the research of linguistics. Natural language processing techniques typically include text processing, semantic understanding, machine translation, robotic question and answer, knowledge mapping, and the like.

In one embodiment, the method may extract keyword tags such as object name, person name, and location and sensitive word tags such as "cancer" and "xx disease" in the verification content based on the NER (Named Entity recognition) function of the Bert model, calculate the digest of the verification content based on the transform model, and calculate the category of the verification content based on the LSTM (Long Short-Term Memory) model. The generated information verification result may include verification content, keyword tags and sensitive word tags, summary and category information. The sensitive words are words preset by the false information management system and can be set according to the keywords of the false information in the system.

In an embodiment, the first node may include a proving node, the information to be managed includes information verification contract information, and the obtaining of the information to be managed based on the false information may include:

and performing semantic identification, fragment extraction and classification on the basis of the false information and the checking request to obtain an information checking contract.

The authentication node can be a server of an authentication user in the system, the authentication node is connected with the terminal through a network, and the authentication user can send a verification request to the authentication node through the terminal.

The terminal can display an authentication page, and an authentication user can input a verification request on the authentication page. The verification request carries false information to be verified, or keywords of the false information, or identification information of the false information in the system of the application. For example, a request for verification may appear as "do the snow melt poison the eyes, is it real? ", the request for verification contains false information that the snow melt agent is toxic and injuring the eye".

Referring to fig. 5e, the verification node may perform semantic understanding on the verification request according to the natural language processing technology, determine the problem to be verified by the verification user, and perform keyword extraction and classification on the false information carried in the verification request to obtain the tag and category information of the verification request.

The verification request should also carry basic information for generating the contract, such as executing parties of the contract, obligations and rights of the executing parties, and the like. In this embodiment, one party of the contract may be determined as a verification user who initiates a verification request, the other party of the contract is a verification mechanism in the blockchain, the verification user may select some specific verification structures as the other party of the contract, or all the verification mechanisms in the blockchain may be set as the other party of the contract. In one embodiment, the obligation of the certifying organization is to certify the false information and send the certified content to the certifying user, and the right of the certifying organization is to obtain the corresponding fee. The right of the user is to obtain the verification content uploaded by the verification organization aiming at the false information, and the obligation of the user is to pay the verification organization.

Based on the question to be verified by the user, the tag information, the category information, and the basic information, the information verification contract can be generated by clarifying the information such as the right and obligation of both parties or both parties of the contract, and the condition for agreement of the contract.

In an embodiment, the information to be managed further includes current information verification event information, the acquiring information to be managed based on the false information, and the acquiring information to be managed based on the false information further includes the following steps:

and acquiring current information checking event information according to the information checking contract and the current block data in the block chain.

The information verification contracts periodically check the automaton state of the nodes, traversing the automaton state, events, and trigger conditions of the nodes contained within each contract piece by piece. (the automaton in this is an important foundational base of computer science, which is commonly referred to as a finite state machine in the field of software development, and is a very widely used software design model.) the current event can be determined from the automaton state, and the trigger conditions for the execution of the preset contract steps in the information verification contract. For example, information verification contracts specify: the verification node can write the information verification result into the block chain as a first trigger condition, the verification user can confirm the information verification result, and the confirmation operation of the verification user can be used as a second trigger condition. When the state of the automaton meets the triggering condition, generating a corresponding event, writing the generated current event into the block chain, and triggering the step in the information checking contract. For example, when the user is certified to determine that the corresponding event is written into the block chain, the step of automatic payment is triggered.

In one embodiment, the information verification contract defines a verification fee, the information to be managed further includes payment transaction information, and the acquiring of the information to be managed based on the false information further includes the following steps:

and when the current information checking event information meets the payment triggering condition, triggering to carry out payment transaction to obtain payment transaction information.

Payment evidence is a business change revenue-generating scheme provided by the false information management system of the application, so that the resources of the checking institution in the system can be configured more optimally. The payment transaction information comprises identity information of both transaction parties, transaction time information, articles used for transaction and the like. The signature information and the transaction time information of the identity information of both parties of the transaction can be expressed as a timestamp, and the article used for the transaction can be expressed as the content of the verification and the like.

Of course, there may be a public interest verification organization node without payment in the false information management system, and the public interest verification organization node may also obtain the information verification contract in the blockchain. The user can select paid verification, free verification, or priority free verification and the like when setting the verification application. According to the application, a corresponding information check contract may be generated, and trigger conditions for the contract execution step are specified within the information check contract (the trigger conditions include trigger party identity). For example, when the user sets a priority free check and sets a priority time, only the automaton state of the node of the public interest checking organization can satisfy the triggering condition within the priority time, and the paying checking organization uploads the information checking result immediately and cannot trigger the step of executing the information checking contract.

102. And generating verification information according to the information to be managed, wherein the verification information comprises the information to be managed and the signature information of the first node.

The signature information is a digital string which can be generated only by the sender of the information and cannot be forged by others, and the digital string is also a valid proof of the authenticity of the information sent by the sender of the information.

In an embodiment, the hash signature may be encrypted using HTTPS (hypertext Transfer Protocol over secure socket Layer) network transport Protocol. When the first node and the second node join the block chain, the first node and the second node negotiate to obtain a symmetric key through the interaction of handshake messages, and HTTPS communication is established. The encryption and decryption in the symmetric encryption algorithm use the same key, that is, a symmetric key, and when the first node transmits the information to be managed to the second node, the symmetric key is used for signing, and the specific steps may include: and the first node performs Hash operation on the information verification result to obtain a Hash value 1, then performs encryption operation on the Hash value by using a symmetric key of the first node to generate signature information, and then broadcasts the information verification result and the signature information to a second node in the block chain. And the second node decrypts the signature information through the symmetric key corresponding to the first node to obtain a hash value 1, and proves that the signature information belongs to the first node. And then carrying out Hash operation on the information checking result to obtain a Hash value 2, wherein if the Hash value 1 is consistent with the Hash value 2, the information checking result is not changed in the transmission process from the first node to the second node.

In an embodiment, the information to be managed includes an information verification result, and the generating of the verification information according to the information to be managed may specifically include the following steps:

and generating the verification information according to the signature information, the public content and the encrypted private content.

Specifically, an RSA encryption algorithm may be used to perform encryption operation on the private content to obtain the encrypted private content, where the RSA encryption algorithm is an asymmetric encryption algorithm, and usually a pair of RSA keys is generated first, and one of the RSA keys is a secret key and is stored by the first node; the other is a public key which can be externally disclosed, and the secret key and the public key are different and can not be mutually deduced. When the information verification result is sent to the second node in the block chain, the public key is not sent to the second node, so that the secret content can be kept secret.

In one embodiment, the verification mechanism may set the content to be verified as private content, and the summary, tag, category, etc. information of the content to be verified as public content. The staff of the checking organization can set private content and public content through a display interface on the terminal.

When the information verification structure is stored in the block chain, the verification mechanism may set a condition for viewing the private content (for example, the content viewing condition is a fee paid by the viewer), and generate a content viewing contract according to the condition. When the content viewing condition is satisfied, the public key is sent to the viewer. When the content viewing condition is that a viewer pays a fee, transaction information generated for viewing the private content needs to be stored in the blockchain. The transaction information comprises the identity of both transaction parties, articles used for transaction, transaction time and other information. Therefore, the copyright of private contents of a checking organization can be guaranteed, for example, if a viewer has copyright dispute with the checking organization, the transaction information in the block chain can provide a certificate.

In another embodiment, the content may be subjected to semantic recognition, segment extraction and classification in the terminal to obtain an abstract, a tag and category information, and the abstract, the tag, the category information and the content may be combined to obtain an information verification result. And then generating verification information, wherein the verification information comprises an information verification result and signature information of the terminal. The signature information may be obtained by encrypting the hash value of the verification result information using a symmetric key. And then transmitted to the verification node through an HTTPS network transmission protocol. The verification node may verify the identity of the terminal and the content of the information verification result according to the verification information. For a specific process, refer to the above verification process between the first node and the second node, which is not described again.

103. And storing the information to be managed into the block chain based on the verification information, and enabling nodes in the block chain to achieve consensus based on the information to be managed based on a consensus algorithm of the block chain.

Before writing into the block chain, the second node in the block chain may perform node identity verification and information content verification according to the check information, and if the verification passes, the second node is written into the block chain. Verification is required before writing to the blockchain: firstly, whether the information to be managed comes from a first node or not; second, whether the information to be managed is changed during transmission.

In an embodiment, the verification information includes a symmetric key, signature information, and information to be managed, the first node may decrypt the signature information with the symmetric key to obtain a hash value, perform hash operation on the information to be managed to obtain the hash value, and if the hash values are consistent, the verification is deemed to be passed. Through verification, the information transmission process between the terminal and the first node can be guaranteed not to be tampered, and therefore authenticity of data written into the block chain can be guaranteed.

In an embodiment, the block chain includes a first block data chain, and the storing the information to be managed into the block chain may include:

When the process of writing the information to be managed into the block chain and sending the information to be managed to other nodes in the block chain by the first node is described, the other nodes are called second nodes, and the concepts of the second nodes mentioned in the first embodiment and the second nodes in the second embodiment are not completely consistent.

The relationship between the second node and the first node in the first embodiment is different identities (respectively, an information sender and an information receiver) in the same process (i.e., a process of storing information into a block chain). The relationship between the first node in embodiment one and the second node in embodiment two is the performer of the different processes (storing information to and retrieving information from the blockchain, respectively).

By adding a timestamp to the data on the block chain, the right of the information to be managed corresponding to the data can be confirmed, wherein the right confirmation is to confirm the copyright of the data. The consensus algorithm of the block chains at the same time can also enable each node in the block chains to carry out copyright identification on the information to be managed added into the block chains.

In this embodiment, each node in the false information management system stores at least one identical blockchain. Each block data chain holds a kind of information to be managed.

The block data chain is composed of a plurality of blocks, the starting block comprises a block head and a block main body, the block head stores an input information characteristic value, a version number, a timestamp and a difficulty value, and the block main body stores input information; the next block of the starting block takes the starting block as a parent block, the next block also comprises a block head and a block main body, the block head stores the input information characteristic value of the current block, the block head characteristic value of the parent block, the version number, the timestamp and the difficulty value, and the like, so that the block data stored in each block in the block data chain is associated with the block data stored in the parent block, and the safety of the input information in the block chain is ensured.

When each block in the block data chain is generated, referring to fig. 1, when the second node receives the verification information, verifying the verification information, after the verification is completed, storing the information to be managed and the signature information into a memory pool, and updating a hash tree used for recording the verification information; and then, updating the updating time stamp to the time when the verification information is received, trying different random numbers, and calculating the characteristic value for multiple times, so that the calculated characteristic value can meet the following formula:

SHA256(SHA256(version+prev_hash+merkle_root+ntime+nbits+x))<TARGET

wherein, SHA256 is a characteristic value algorithm used for calculating a characteristic value; version is version information of the relevant block protocol in the block chain; prev _ hash is a block head characteristic value of a parent block of the current block; merkle _ root is a characteristic value of the input information; ntime is the update time of the update timestamp; nbits is the current difficulty, is a fixed value within a period of time, and is determined again after exceeding a fixed time period; x is a random number; TARGET is a feature threshold, which can be determined from nbits.

In an embodiment, the consensus algorithm based on the block chain enables the nodes in the block chain to achieve consensus based on the information to be managed, which may specifically include the following steps:

For example, the information to be managed is taken as an example of information checking and approving to be described in detail, and each node in the network receives a contract; the verification node in the network stores the received contract into the memory first, and then waits for a new round of consensus time to trigger consensus and processing of the contract.

When the consensus time is up, the verification node packs the contracts stored in the memory into a contract set, then calculates the hash value of the contract set, assembles the hash value of the contract set into a block and diffuses the block into the network.

After receiving the block structure, other nodes in the block chain take out the hash value of the contract set contained in the block chain and compare the hash value with the contract set stored by the other nodes; simultaneously sending a contract set approved by the user to other nodes; through such multiple rounds of sending and comparing; all nodes in the blockchain eventually agree on the latest contract set within a specified time. Of course, for different consensus algorithms, it may not be required that all nodes in the blockchain agree, and when a predetermined number of nodes agree, consensus may also be considered to be reached.

Therefore, the nodes in the block chain can reach the consistency with the information to be managed through the consensus algorithm, and the data can be prevented from being changed randomly, so that the safety of the data is guaranteed.

Optionally, when the system user disagrees the information to be managed, or after checking by the first node user, it is determined that the previously uploaded information to be managed is incorrect, the first node user may be allowed to modify or supplement the correct information to be managed, the modified or supplemented information needs to specify the location of the corresponding information to be managed, that is, the address location of the previously uploaded information to be managed in the block data chain, and the modified and supplemented records (including modification time information and modifier identity information) are also stored in the block chain, and a consensus is achieved. Wherein the modification time information may be represented as a time stamp and the modifier identity information may be represented as modifier signature information.

Therefore, the information to be managed related to the false information is stored in the block chain, the information to be managed can be prevented from being tampered based on the consensus algorithm of the block chain, the authenticity, the credibility and the safety of the information can be guaranteed, and meanwhile the block chain can more directly and more widely spread the information to be managed based on the false information, so that the false information can be more effectively treated.
