Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art based on the embodiments herein without making any inventive effort, are intended to be within the scope of the present application.

First, the blockchain, the block, the chain, the consensus mechanism, and the smart contracts mentioned in the embodiments of the present application are described.

1. Blockchain: in a narrow sense, the blockchain is a chain data structure taking a block as a basic unit, and the block uses a digital abstract to verify the previous transaction history, so that the requirements of tamper resistance and expandability in a distributed billing scene are met; in a broad sense, blockchain also refers to distributed accounting techniques implemented by blockchain structures, including distributed consensus, privacy and security protection, point-to-point communication techniques, network protocols, smart contracts, and the like. The goal of the blockchain is to implement a distributed data logging ledger that allows only additions and not deletions. The basic structure of the ledger floor is a linear linked list. The linked list is formed by serially connecting blocks, the Hash value of the preceding block is recorded in the following blocks, and whether each block (and the transaction in the block) is legal or not can be rapidly checked by calculating the Hash value. If a node in the network proposes to add a new block, it must be acknowledged by the consensus mechanism.

2. Block (Block): all transactions and status results occurring within a period of time are recorded and are a consensus of the current ledger status. Specifically, for a blockchain, each time data is written, the transaction process described above creates a block.

3. Chain (Chain): the system is formed by serially connecting blocks according to the occurrence sequence, and is a log record of the state change of the whole account book.

4. Consensus mechanism: the verification and confirmation of the transaction is completed in a short time by voting of the special nodes, and the aim is to enable all honest nodes to store a consistent block chain diagram.

5. Intelligent contract: the working principle of the intelligent contract is similar to if-then statement implemented in program code, and when a preset condition is triggered, the intelligent contract executes corresponding contract terms. Smart contracts are a set of digitally defined commitments that include agreements on which contract participants can perform.

Specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of a blockchain according to an embodiment of the present application. As shown in fig. 1, a blockchain is composed of blocks, each of which includes two parts: a chunk header and a chunk, and the chunk header includes a timestamp, a current hash value, and a successor hash value. The time stamp is used for recording the generation time of the block; the current hash value is the hash value of the block; the preceding hash value is the hash value of the preceding block of the block; and the block body is transaction information stored for the block body. Specifically, taking the example that the second block is added to the blockchain, the new block is generated as follows:

When the blockchain has the first block 101, the first block 101 is configured to instruct the first transaction data generated by the first transaction, generate second transaction data through the second transaction if the second transaction occurs, and generate the second block 102 through the second transaction data if the second transaction data passes verification, and be added into the blockchain as a subsequent block of the first block 101. Wherein, the timestamp included in the block header of the second block 102 is used for recording the generation time of the second block 102; the current hash value is a hash value generated by the blockchain system from the data contained in the second block 102; the preceding hash value is the hash value of the first block 101; the block body of the second block 102 is used for recording second transaction data.

Similarly, a third block 103 is added to the blockchain, the third block 103 being used to indicate third transaction data generated by a third transaction. If a new transaction occurs in the transaction chain indicated by the blockchain, generating a subsequent block and adding the subsequent block into the blockchain according to the mode of generating a new block by the same principle.

Specifically, referring to fig. 2, fig. 2 is an information release architecture diagram provided in the embodiment of the present application, as shown in fig. 2, when a publisher publishes a message through a first client, a service server sends the user release information to a blockchain network, where the service server is a server corresponding to the first client, the user release information includes user information, release content, release platform information and release time, where the user information is relevant information of the publisher, such as personal information and/or a network interconnection protocol (Internet Protocol, IP) address of the first client, and the release content is a message released by the publisher, and the release platform information is used to indicate which platform the publisher publishes the message. After receiving the user release information, the blockchain network generates a release block, adds the release block into the user data blockchain, and can inquire at least one block comprising any release content when any release content needs to be inquired, and sends the at least one block to the front-end equipment. Optionally, when the reloading party reloads the message issued by the issuing party through the second client, the reloading information issued by the reloading party is added into the blockchain through the blockchain network, so that any message on the internet can be queried to the corresponding issuing party.

Referring to fig. 3, fig. 3 is a flowchart of a block chain-based information distribution management method according to an embodiment of the present application. As shown in fig. 3, the information distribution management process includes the steps of:

step S301, obtain the user release information sent by the service server.

Specifically, user release information sent by a service server is obtained, wherein the user release information comprises the user information, release content, release platform information and release time. Wherein the user information includes personal information and/or IP address of the user who published the published content, etc. Specifically, when a user publishes a message on a certain exchange platform, a service server corresponding to a client used by the user can be regarded as a participating node in the blockchain network, and the service server sends user publishing information according to the message published by the user, where the user publishing information includes user information of the user, publishing platform information of the certain exchange platform, published message content and time of publishing the message, and here, the service server can be regarded as sending the user publishing information to an information publishing management system, where the information publishing management system is a alliance chain in the blockchain network and is used for managing the messages published by each user.

For example, assume that user a issues "today catches up with XX's first project on the first communication platform, XX's performance …, movie entirety …, listen to …", and when a service server used by user a detects that there is a message issue, user information of the user a, message content issued by user a, issue platform information of the first communication platform, and time when the user a issues the message content are acquired to generate user issue information, the user issue information is sent to the information issue management system to send a request for linking the user issue information, and the information issue management system receives the user issue information sent by the service server. When any exchange platform receives the information issued by the user and is equivalent to detecting that the information is issued, the user issuing information is determined according to the content, the issuing time and the information of the platform and the information of the user issuing the information, and the user issuing information is sent to the information issuing management system and carries a uplink request.

Step S302, generating a release block according to the user release information, and adding the release block into a user data block chain.

Specifically, the information release management system generates a release block according to user release information, wherein the release block comprises user information, release content, release platform information and release time in the user release information, the user release information forms data in a block body of the release block, and the release block is added into a user data block chain. Wherein the user data blockchain is used for storing relevant information of each message propagated on the network.

Specifically, after acquiring user release information sent by a service server, an information release management system composes a block to be added according to a uplink request carried by the user release information, release content, release platform information and release time, and after verifying the block to be added, the block to be added is used as data in a block body of the release block to generate the release block, and the release block is added into a user data block chain.

Step S303, when detecting that the released content is illegal content, acquiring at least one query block containing the illegal content, packaging the at least one query block as propagation information, and sending the propagation information to the front-end equipment.

Specifically, when the information release management system detects that release content is illegal content, inquiring is performed through the illegal content to obtain at least one inquiry block, each inquiry block in the at least one inquiry block contains the illegal content, the at least one inquiry block is packaged into propagation information, and the propagation information is sent to the front-end equipment. When the release content is illegal content, the release content contains one or more illegal key word groups, at least one query block containing the one or more illegal key word groups is searched from all blocks which are already linked up through the one or more illegal key word groups, and the at least one query block is sent to front-end equipment, wherein the front-end equipment is a manager with the query authority of the information release management system. The front-end device may determine, according to the received at least one query block, related information of each message including the one or more illegal key word groups, where the related information includes user information, located publishing platform information, and publishing time corresponding to a publisher of each message. Optionally, after obtaining at least one query block, the publishing time in each query block may be obtained, the query block with the smallest publishing time is taken as a target block, the target block is packaged as propagation information, and the propagation information is sent to the front-end device, so as to determine the propagation source of the publishing content.

According to the method and the device for processing the user release information, the user release information comprises user information, release content, release platform information and release time, the release block is generated according to the user release information, the release block is added into a user data block chain, when the release content is detected to be illegal content, at least one query block can be obtained according to the illegal content, the at least one query block is packaged to be propagation information, and the propagation information is sent to front-end equipment, wherein each query block in the at least one query block contains the release content. Due to the decentralization and the non-tamper property of the block chain, the information release data are public and transparent to the management node with the query authority, and the accuracy, the reliability and the traceability of the information release data record are improved. Each piece of release content released on the Internet is uploaded to the blockchain, so that when any release content needs to be queried, the release or spreading condition of the release content can be obtained, and the release content is traced, so that when the release content is illegal, reminding or warning of a user releasing or spreading the illegal content can be realized through querying the illegal content, and the effectiveness and accuracy of information release management are improved. And when the communication platform is closed or a problem occurs, the release content of each user recorded in the communication platform is deleted, namely, the release content of each user recorded in the communication platform does not exist on a network or in a server, all the release contents stored and recorded in the communication platform, the user information and release time of the release contents and the like can be searched through tracing in an information release management system, so that the condition that the release content cannot be obtained can be avoided, and when the release content is illegal, the release condition of the release content can be comprehensively obtained as far as possible, and the information release management is more efficient, accurate and comprehensive.

Referring to fig. 4, fig. 4 is a schematic flowchart of a block chain-based information distribution management method according to an embodiment of the present application. As shown in fig. 4, the information distribution management method includes the steps of:

step S401, user release information sent by a service server is obtained.

Specifically, when a user sends a message through a first client, a service server corresponding to the first client sends relevant information of the message to an information release management platform, and the information release management platform acquires user release information sent by the service server, wherein the user release information is relevant information of the message released by the user and comprises user information, release content, release platform information and release time of the user. Specifically, when a user issues a message through a first communication platform, the first communication platform detects that the message is issued, then obtains an issue account of the currently issued message, obtains personal information of the user and/or an IP address of a first client through the issue account, uses the personal information and/or the IP address of the first client as user information for issuing the message, and obtains issue time of the message.

Specifically, referring to a schematic information distribution scenario shown in fig. 5, when a user 1 performs information distribution on an information display page 50 of a first exchange platform in a first client, clicks a link for distributing information, sends an information distribution request to the first exchange platform, when the first exchange platform receives the information distribution request, detects the information distribution condition of the user 1, when the information distribution of the user 1 is successful, the first exchange platform obtains user information, distribution content and distribution time of the user 1, generates user distribution information, displays the user distribution information in the information display page 50, and sends the user distribution information to an information distribution management platform through a service server. The service server may be a server corresponding to the first communication platform, or may be a server corresponding to the first client.

Step S402, determining a user data blockchain to which the user information belongs.

Specifically, a user data blockchain to which the user information belongs is determined according to the user information and the release platform information. In the information distribution management platform, each piece of data blockchain can be determined by the information of the distribution platform and the information of the user, specifically, a storage space in the information distribution management platform can be partitioned, each block stores the information distribution condition of one communication platform, each block records a plurality of pieces of data blockchains, each piece of data blockchain corresponds to the information distribution condition of one user in the communication platform, each piece of data blockchain is uniquely determined by the information of the distribution platform and the information of the user, or is uniquely determined by the identification of the information of the distribution platform and the identification of the information of the user, and at the moment, the corresponding relation between the identification of the information of the distribution platform and the identification of the information of the user and the information of the user is recorded; or, in the information release management platform, a plurality of data blockchains are stored, one data blockchain is used for storing and maintaining information released on one communication platform, namely, different communication platforms correspond to different data blockchains, and each data blockchain contains information release conditions of each user in the corresponding communication platform; or, in the information release management platform, a plurality of data blockchains are stored, one data blockchain is used for storing and maintaining information released by one user on various communication platforms, namely, different users correspond to different data blockchains, and each data blockchain contains information release conditions of the corresponding user in each communication platform; or, in the information distribution management platform, there is only one data blockchain, and the information distribution situation of each user in each communication platform is contained in the data blockchain. The above is a plurality of different recording modes provided in the scheme, each recording mode can be used for recording information release conditions in the information release management platform, and each recording mode corresponds to a distribution condition of a data blockchain in the information release management platform.

Referring specifically to fig. 6a, a schematic diagram of a data blockchain distribution scenario is provided in an embodiment of the present application. In fig. 6a, a piece of data blockchain can be uniquely determined by publishing platform information and user information, a partition of an affiliated communication platform in an information publishing management system is obtained by publishing platform information, and then the user data blockchain to which the user information belongs is searched from the partition of the communication platform according to the user information. For example, in the example of step S401, the first communication platform partition 601 is searched according to the publishing platform information, and then the user data blockchain corresponding to the user 1 is searched from the first communication platform partition 601. The method can mark each piece of data blockchain in the information release management system through the identification of the user information and the identification of the release platform information, and simultaneously store the corresponding relation between the identification of each release platform information and the release platform information, and between the identification of each user information and the user information, as shown in the corresponding relation table 60 a.

Specifically, fig. 6b is a schematic diagram of still another data blockchain distribution situation provided in the embodiment of the present application, which is to directly store the information release situation of each user in each communication platform through one data blockchain, which is equivalent to directly searching the data blockchain recorded in the information release management system when receiving the user release information, that is, the user data blockchain to which the user information belongs.

When the user information or the release platform information is used for data blockchain division, the user data blockchain to which the user information belongs is searched according to the user information or the release platform information.

Step S403, generating a release block according to the user release information, and adding the release block into the user data block chain.

Specifically, a release block is generated according to user information, release content, release platform information and release time in the user release information, and the release block is added into a user data block chain. Specifically, generating a block to be added according to user information, release content, release platform information and release time; and verifying the block to be added through a consensus mechanism, and if the verification is passed, generating a release block according to the user data block chain and the block to be added, and adding the release block into the user data block chain. After the block to be added passes the verification, a historical block in the user data block chain and a hash value of the historical block are obtained, the historical block is a block with the latest timestamp in the user data block chain to which the user information belongs, the timestamp is a generation time in a block head of the block, the hash value generated according to the block to be added is used as a current hash value, the hash value of the historical block is used as a former hash value, the current network time is obtained, the current network time is used as a timestamp, and a release block is generated according to the block to be added, the current hash value, the former hash value and the timestamp, and the timestamp is a generation time in the block head of the release block. Referring specifically to the issue block 6031 in fig. 6b, the issue block 6031 includes a block header 6031a and a block body 6031b, wherein the block header 6031a includes a generation time, a current hash value, and a previous hash value, and the previous hash value is a hash value of a history block, and the block body 6031b includes user issue information, such as user information, issue content, issue platform information, and issue time. Alternatively, hash calculation can be performed according to the user information and the release platform information to obtain a combined hash value of the user information and the release platform information, the release platform information and the user information corresponding to the combined hash value are directly and uniquely identified in each block, and then the release platform information and the corresponding relation between the user information and the combined hash value are recorded.

For example, referring to fig. 7, when a service server corresponding to a first client sends a request for uplink to send a block to be joined to other participating nodes in the information distribution management system, the user of the block to be joined indicates that the first client is to distribute a '…' message on a first communication platform, the other participating nodes in the information distribution management system, including but not limited to a second, third, fourth and other participating nodes, receive the block to be joined, verify the block to be joined through a consensus mechanism, send a verification result to the information distribution management system, if the verification is passed, the information distribution management system generates a distribution block, and adds the distribution block to a user data blockchain to realize the operation of uplink the distribution block. The method comprises the steps that other participating nodes can analyze the block to be added, user information, release content, release platform information and release time of a publisher are determined, the information is released in a first communication platform according to the release platform information, then the information released by a user account corresponding to the user information at the release time is obtained from the first communication platform, whether the information is consistent with the release content or not is determined, if so, the block to be added is clear, and a verification result is sent to an information release management platform, the information release management platform carries out consensus according to the verification result of the other participating nodes, confirms the accuracy of the block to be added, generates a release block according to the block to be added and a user data block chain, and links the release block.

Step S404, determining that the release content in the user release information is illegal content.

Specifically, it is detected that the distribution content is illegal content. When an illegal message acquisition request sent by front-end equipment is received, the illegal message acquisition request comprises release content, and the release content is determined to be illegal content according to the illegal message acquisition request; or acquiring illegal key word groups contained in the release content, counting the number of the illegal key word groups, determining the sensitive value of the release content according to the number of the illegal key word groups and the sensitive weight corresponding to the illegal key word groups, and determining the release content as the illegal content if the sensitive value is larger than a parameter threshold. Before receiving an illegal message obtaining request sent by front-end equipment, obtaining user information corresponding to the front-end equipment, determining information query authority of the front-end equipment based on an intelligent contract and the user information corresponding to the front-end equipment, wherein the intelligent contract is used for determining the information query authority of a user corresponding to the front-end equipment according to the user information corresponding to the front-end equipment, if the front-end equipment has the information query authority, sending a query key to the front-end equipment, and receiving the illegal message obtaining request sent by the front-end equipment based on the query key and aiming at the release content. Because the user information in each block recorded in the information distribution management system contains the personal information of the user, the personal information comprises real-name information, privacy protection is required, the data of each block can be acquired in the information distribution management platform only when the information query right is provided, specifically, at least one execution process can be set in the intelligent contract, including "if the user information is provided with the information query right, a query key is sent to the front-end device corresponding to the user information", and "if the received illegal message acquisition request carries the query key, the relevant block is queried, and the query result is fed back to the front-end device", or "if the user information is the recorded user with the information query right, the query result is fed back to the front-end device" can be directly executed after the illegal message acquisition request is received.

Because of the strong freedom of speaking on the network, many people can show how well when they are publishing their own speech on the network through the virtual account number, and the sense that they cannot express in real life can be revealed on the network, including the situation that some users can maliciously rumble on the network, leading the comments of the masses, and even if one virtual account number is sealed, new virtual account numbers can be reapplied, so that the information on the network is difficult to manage. Also, in this case, it is likely that the normal life of a certain user is disturbed due to "network violence". Therefore, management of individual messages on the network is particularly important. After the release content is released to the first communication platform for a period of time, the manager discovers that one evaluation of the user XXX is not real, and sends an illegal message acquisition request according to the release content corresponding to the un-real evaluation of the user XXX, and determines the release content as illegal content; or when the information release management system adds the release block into the user data block chain, acquiring release content in the release block, comparing the release content with an illegal keyword library to obtain illegal keyword groups contained in the release content, determining a sensitive value of the release content through the number of the illegal keyword groups and the weight corresponding to each illegal keyword group, and determining the release content as illegal content when the sensitive value is larger than a parameter threshold value so as to realize real-time monitoring of messages released on a network.

Step S405, at least one query block containing illegal contents is obtained, and propagation information is obtained according to at least one query block package.

Specifically, at least one query block is searched according to illegal contents, each query block in the at least one query block contains the illegal contents, the at least one query block is packaged into propagation information, and the propagation information contains all information of the illegal contents from the release to the propagation; the query block with the earliest release time recorded in the at least one query block comprises a transmission source of the illegal content. Or after obtaining at least one query block, obtaining the release time in each query block, determining the query block with the earliest release time as a target block, and packaging the target block as propagation information to obtain the propagation source of the release content. Wherein, at least one query block can be packaged as propagation information in the form of 'release content' "which is released by the user 1 on the first communication platform through the" X point on XX month XX day X; alternatively, if the propagation source of a certain illegal content needs to be known, the query block with the earliest release time in at least one query block can be determined as a target block, and the target block can be directly packaged as propagation information. In an alternative case, for example, if an illegal content is propagated on the network, and the illegal content is related to reputation damage to others, and when the influence is great, the relevant department needs to solve the propagation of the illegal content from the source, that is, needs to find the rumor, in order for the relevant department to look over, the block with the earliest issue time in the block associated with the illegal content can be directly obtained, and the block with the earliest issue time is sent to the relevant department, so that the relevant department alerts or penalizes the user corresponding to the user information recorded in the block. It is considered that the process in this alternative case may be performed when the number of the found at least one query block containing illegal contents is large and the propagation source of the illegal contents needs to be known.

Step S406, the propagation information is sent to the front-end equipment.

Specifically, the propagation information is sent to a front-end device, where the front-end device is a manager with information query authority, and optionally, the release content may also be disclosed to inform each user that the release content is illegal. If the propagation information of the request package is obtained according to the illegal message sent by the front-end equipment, the propagation information is directly sent to the front-end equipment; if the propagation information of the distribution condition package of each message is monitored, the contact mode of the manager is acquired, and the propagation information is sent to the manager.

Optionally, in another possible information release management manner, after executing steps S401 to S402, when verifying a block to be added through a consensus mechanism in step S403, other participating nodes may acquire an illegal key phrase in the release content, determine a sensitive value of the release content to determine whether the release content is illegal content, if the release content is illegal content, directly execute step S405, determine a query block related to the release content, and package the query block as propagation information to a front-end device, if the release content is not illegal content, verify through the consensus mechanism, generate a release block if the verification passes, uplink the release block, and end the information release management process.

According to the method and the device, user release information sent by a service server is obtained, the user release information comprises user information, release content, release platform information and release time, a release block is generated according to the user release information, the release block is added into a user data block chain, when the release content is detected to be illegal content, at least one query block containing the illegal content is obtained, the at least one query block is packaged to be propagation information, and the propagation information is sent to front-end equipment. Each message issued on the network is recorded in the information issuing management system, the information issuing management system is a block chain network, and the recorded blocks corresponding to each message are credible and accurate due to the non-falsification of the block chain, so that when the issued content has problems, the issued content can be traced back, and the effectiveness, the high efficiency and the accuracy of the information issuing management are improved. When some users issue a speech, and the speech is injured by others, the true or false of the speech cannot be immediately confirmed, and when the fact that the speech is not real is confirmed later, the problem of the fact that the speech is not real can be traced back to obtain the issue and propagation condition of the problem of the fact that the problem of the fact is not real is solved, and the problem of the fact that the problem of the fact is not real is managed through the issue and propagation condition of the problem of the fact. Further, the unreal speech can be traced to obtain the block with the earliest release time, so that the release source of the unreal speech is determined, the rumor source of the unreal speech is determined, and the management of information release is realized from the rumor source. Optionally, the publishing source of each piece of illegal content can be recorded, the publishing source comprises real-name information corresponding to user information, if the number of times that a certain real-name user is the publishing source exceeds the preset number of times, the real-name user can be warned, serious punishment can be carried out, and therefore management of information publishing is fundamentally achieved, and network environment is managed.
