Detailed Description

The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.

First, a block chain, a block, a chain, a consensus mechanism, and an intelligent contract, which are mentioned in the embodiments of the present application, are introduced.

1. Block chains: in a narrow sense, a block chain is a chain data structure taking a block as a basic unit, and the prior transaction history is verified by utilizing a digital abstract in the block, so that the block chain is suitable for the requirements of tamper resistance and expandability under a distributed accounting scene; in a broad sense, blockchain also refers to distributed accounting techniques implemented by blockchain architecture, including distributed consensus, privacy and security protection, peer-to-peer communication techniques, network protocols, intelligent contracts, and the like. The goal of the blockchain is to implement a distributed data record ledger that allows only additions and not deletions. The basic structure of the ledger bottom layer is a linear linked list. The linked list is composed of a series of 'blocks', the Hash (Hash) value of the previous block is recorded in the subsequent block, and whether each block (and the transaction in the block) is legal or not can be quickly checked by calculating the Hash value. If a node in the network proposes to add a new block, the block must be acknowledged through a consensus mechanism.

2. Block (Block): all transactions and status results, etc. occurring over a period of time are recorded, which is a consensus on the current ledger status. Specifically, for a block chain, each time data is written, i.e. the above transaction process, a block is created.

3. Chain (Chain): the blocks are connected in series according to the occurrence sequence and are log records of the state change of the whole account book.

4. A consensus mechanism: the verification and validation of the transaction is accomplished in a short time by voting of the particular nodes, with the goal of having all honest nodes maintain a consistent blockchain graph.

5. Intelligent contract: the working principle of the intelligent contract is similar to if-then statements implemented in program code, and when a preset condition is triggered, the intelligent contract executes corresponding contract terms. An intelligent contract is a set of commitments defined in digital form, including agreements on which contract participants can execute the commitments.

Specifically, referring to fig. 1, fig. 1 is a schematic structural diagram of a block chain according to an embodiment of the present disclosure. As shown in fig. 1, a block chain is composed of blocks, each of which includes two parts: a chunk header and a chunk body, and the chunk header includes a timestamp, a current hash value, and a next 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 previous hash value is the hash value of the previous block of the block; and the block body is used for storing the transaction information for the block. Specifically, taking the example of adding the second block to the block chain, the manner of generating the new block is as follows:

when the first block 101 exists in the block chain, the first block 101 is used for indicating first transaction data generated by a first transaction, if a second transaction occurs, second transaction data is generated through the second transaction, and if the second transaction data passes verification, a second block 102 is generated through the second transaction data and is added into the block chain as a subsequent block of the first block 101. The timestamp contained in the block header of the second block 102 is used to record the generation time of the second block 102; the current hash value is a hash value generated by the blockchain system through the data contained in the second block 102; the subsequent hash value is the hash value of the first block 101; the block of the second block 102 is used for recording the second transaction data.

Similarly, a third block 103 is added to the block chain, and the third block 103 is used for indicating third transaction data generated by a third transaction. If a new transaction occurs in the transaction chain indicated by the block chain, a new block is generated according to the same manner, and a subsequent block is generated and added into the block chain.

Specifically, referring to fig. 2, fig. 2 is an information publishing architecture diagram provided in an 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 publishing information to a blockchain network, the service server is a server corresponding to the first client, the user publishing information includes user information, publishing content, publishing platform information and publishing time, the user information is related information of the publisher, such as personal information and/or an Internet Protocol (IP) address of the first client, the publishing content is a message published by the publisher, and the publishing platform information is used to indicate which platform the publisher publishes the message. After receiving the user release information, the block chain network generates a release block, adds the release block into a user data block chain, and when any release content needs to be queried, can query at least one block including the any release content and send the at least one block to the front-end equipment. Optionally, when the reprinting party reprints the message issued by the issuer through the second client, the reprinting information issued by the reprinting party is also added into the block chain through the block chain network, so that any message on the internet can query the corresponding issuer.

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

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

Specifically, user publishing information sent by the service server is obtained, and the user publishing information includes the user information, publishing content, publishing platform information and publishing time. Wherein the user information includes personal information and/or an IP address of a user who distributes the distributed content. Specifically, when a user publishes a message on a certain communication platform, a service server corresponding to a client used by the user may be considered 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 communication platform, published message content, and time for publishing the message, where the service server may be considered to send the user publishing information to an information publishing management system, and the information publishing management system is a federation chain in the blockchain network and is used to manage messages published by the users.

For example, suppose that a user a publishes "today catches up with XX's first sight, XXX's skill …, movie entirety …, and hears and speaks …" on a first communication platform, when a service server used by the user a detects that there is a message publishing, the user a's user information, the user a's published message content, the first communication platform's publishing platform information, and the time when the user a publishes the message content are obtained to generate user publishing information, the user publishing information is sent to an information publishing management system to send a request for uplink of the user publishing information, and the information publishing management system receives the user publishing information sent by the service server. Each communication platform has a function of sending user release information to the information release management system, when any communication platform receives a message released by a user, which is equivalent to the detection of the release of the message, the user release information is determined according to the content, the release time, the release platform information and the information of the user releasing the message, and the user release information is sent to the information release management system, and carries an uplink request.

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

Specifically, the information publishing management system generates a publishing block according to user publishing information, wherein the publishing block comprises user information, publishing content, publishing platform information and publishing time in the user publishing information, the user publishing information forms data in a block body of the publishing block, and the publishing block is added into a user data block chain. Wherein the user data block chain is used for storing the 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 forms a block to be added with the user information, release content, release platform information and release time according to a uplink request carried by the user release information, verifies the block to be added, uses the block to be added as data in a block body of a release block to generate a release block, and adds the release block into a user data block chain.

Step S303, when it is detected that the release content is an illegal content, acquiring at least one query block containing the illegal content, packaging the at least one query block as the broadcast information, and sending the broadcast information to the front-end device.

Specifically, when the information distribution management system detects that the distribution content is illegal, the information distribution management system queries through the illegal content to obtain at least one query block, each query block in the at least one query block contains the illegal content, encapsulates the at least one query block into the distribution information, and sends the distribution information to the front-end equipment. When the release content is illegal, the release content is indicated to contain one or more illegal key phrases, at least one query block containing the one or more illegal key phrases is searched from each block which is linked up through the one or more illegal key phrases, and the at least one query block is sent to the front-end equipment, wherein the front-end equipment is a manager with 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 keyword groups, including user information corresponding to a publisher of each message, information of a publishing platform where the message is located, and publishing time. Optionally, after obtaining at least one query block, the publishing time in each query block may be obtained, the query block with the minimum publishing time is used as a target block, the target block is encapsulated as the propagation information, and the propagation information is sent to the front-end device to determine the propagation source of the published content.

According to the method and the device, the user release information sent by the service server is received, 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, at least one query block can be obtained according to the illegal content, the at least one query block is packaged to be the spreading information, the spreading information is sent to the front-end equipment, and 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 nodes with the query authority, and the accuracy, the credibility and the traceability of the information release data record are improved. Each piece of published content published on the internet is uploaded to a block chain, so that when any published content needs to be queried, the publishing or spreading condition of the published content can be acquired, and the published content can be traced, so that when the published content is illegal, the illegal content can be queried, reminding or warning of a user who publishes or spreads the illegal content can be realized, and the effectiveness and accuracy of information publishing management can be improved. When the communication platform is closed or a problem occurs, the published contents of each user recorded in the communication platform are deleted, that is, the published contents of each user recorded in the communication platform do not exist on the network or in the server, all the published contents stored and recorded in the communication platform, the user information and the publishing time and the like of the published contents can be found by tracing in the information publishing management system, so that the situation that the published contents cannot be obtained can be avoided, when the published contents are illegal contents, the publishing condition of the published contents can be obtained as comprehensively as possible, and the information publishing management is more efficient, accurate and comprehensive.

Referring to fig. 4, fig. 4 is a schematic view illustrating a specific flow of information distribution management based on a block chain 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 the service server is obtained.

Specifically, when a user sends a message through a first client, a service server corresponding to the first client sends related information of the message to an information distribution management platform, the information distribution management platform obtains user distribution information sent by the service server, and the user distribution information is related information of the message distributed by the user and comprises user information, distribution content, distribution platform information and distribution time of the user. Specifically, when a user publishes a message through a first communication platform, the first communication platform detects that the message is published, a publishing account of the currently published message is obtained, personal information of the user and/or an IP address of a first client is obtained through the publishing account and used as user information for publishing the message, publishing time of the message is obtained, the first communication platform sends the user publishing information to an information publishing management system through a service server corresponding to the first client according to the user information, publishing content and the publishing time, and the information publishing management system obtains the user publishing information sent by the service server.

Specifically, referring to a schematic diagram of an information publishing scene shown in fig. 5, when a user 1 publishes information on an information display page 50 of a first communication platform in a first client, a link of the published information is clicked, an information publishing request is sent to the first communication platform, when the first communication platform receives the information publishing request, an information publishing situation of the user 1 is detected, and when the information of the user 1 is successfully published, the first communication platform acquires user information, publishing content and publishing time of the user 1, generates user publishing information, displays the user publishing information on the information display page 50, and sends the user publishing information to an information publishing 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 block chain to which the user information belongs.

Specifically, the user data block chain to which the user information belongs is determined according to the user information and the publishing platform information. In the information publishing management platform, each data block chain can be determined by publishing platform information and user information, specifically, a storage space in the information publishing management platform can be partitioned, each block stores the information publishing condition of an exchange platform, a plurality of data block chains are recorded in each block, each data block chain corresponds to the information publishing condition of a user in the exchange platform, each data block chain is uniquely determined by the publishing platform information and the user information, or is uniquely determined by an identifier of the publishing platform information and an identifier of the user information, and at the moment, the corresponding relationship between the identifier of the publishing platform information and the corresponding relationship between the identifier of the user information and the user information can be recorded; or, a plurality of data block chains are stored in the information release management platform, one data block chain is used for storing and maintaining information released on one communication platform, namely, different communication platforms correspond to different data block chains, and each data block chain contains the information release condition of each user in the corresponding communication platform; or, a plurality of data block chains are stored in the information release management platform, one data block chain is used for storing and maintaining information released by one user on various communication platforms, namely different users correspond to different data block chains, and each data block chain contains information release conditions of the corresponding user in each communication platform; or, in the information distribution management platform, there is only one data block chain, and the data block chain includes the information distribution situation of each user in each communication platform, that is, the information distribution situation of each user in each platform is in the data block chain. The above is several different recording modes provided in the present solution, each recording mode may be used for recording the information publishing condition in the information publishing management platform, and each recording mode corresponds to a distribution condition of a data block chain in the information publishing management platform.

Specifically, refer to fig. 6a, which is a schematic diagram of a distribution situation of a data block chain according to an embodiment of the present application. In fig. 6a, a data block chain can be uniquely determined by publishing platform information and user information, a block of the communication platform in the information publishing management system is obtained by publishing platform information, and then the user data block chain to which the user information belongs is found from the block of the communication platform according to the user information. For example, in the example of step S401, the first communication platform partition 601 is found according to the publishing platform information, and then the user data block chain corresponding to the user 1 is found from the first communication platform partition 601. The method can mark each data block chain through the identification of the user information and the identification of the publishing platform information in the information publishing management system, and simultaneously store the corresponding relationship between the identification of each publishing platform information and the publishing platform information and between the identification of each user information and the user information, as shown in the corresponding relationship table 60 a.

Specifically, fig. 6b is a schematic view of a distribution situation of another data block chain provided in this embodiment, where the information distribution situation of each user in each communication platform is directly stored through one data block chain, which is equivalent to directly finding out the data block chain recorded in the information distribution management system when receiving user distribution information, that is, the user data block chain to which the user information belongs.

When the data block chain is divided by the user information or the publishing platform information, the user data block chain to which the user information belongs is searched according to the user information or the publishing platform information.

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

Specifically, a publishing block is generated according to user information, publishing content, publishing platform information and publishing time in the user publishing information, and the publishing block is added into the user data block chain. Specifically, a block to be added is generated according to the user information, the release content, the release platform information and the release time; and verifying the block to be added through a consensus mechanism, 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 verification of the to-be-added block is passed, a history block in a user data block chain and a hash value of the history block are obtained, the history block is a block with the latest timestamp in the user data block chain to which the user information belongs, the timestamp is the generation time in a block head of the block, the hash value generated according to the to-be-added block is used as a current hash value, the hash value of the history block is used as a subsequent hash value, the current network time is obtained, the current network time is used as a timestamp, a release block is generated according to the to-be-added block, the current hash value, the subsequent hash value and the timestamp, and the timestamp is the generation time in the block head of the release block. Specifically, as shown in the distribution block 6031 in fig. 6b, the distribution block 6031 includes a block header 6031a and a block body 6031b, where the block header 6031a includes generation time, a current hash value, and a subsequent hash value, the subsequent hash value is a hash value of a history block, and the block body 6031b includes user distribution information, such as user information, distribution content, distribution platform information, and distribution time. Optionally, hash calculation may be performed according to the user information and the publishing platform information to obtain a combined hash value of the user information and the publishing platform information, the publishing platform information and the user information corresponding to the unique identifier of the combined hash value are directly identified in each block, and then the corresponding relationship between the publishing platform information and the combined hash value and the user information is recorded, so that when a large number of messages are published by a same user, the user information and the publishing platform information of the user do not need to be repeatedly recorded, and the user information of the user and the combined hash value corresponding to the publishing platform information are directly recorded, so as to save a storage space.

For example, referring to fig. 7, when the service server corresponding to the first client sends a uplink request, a to-be-joined block is sent to other participating nodes in the information distribution management system, and a user of the to-be-joined block indicates that "the first client is to distribute an '…' message on the first communication platform", where the other participating nodes in the information distribution management system include, but are not limited to, the second, third, and fourth participating nodes, and the other participating nodes receive the to-be-joined block, verify the to-be-joined block through a consensus mechanism, and send a verification result to the information distribution management system, and if the verification is passed, the information distribution management system generates a distribution block, and adds the distribution block to the user data block chain, so as to implement an operation of linking the distribution block. According to the possible consensus mechanism implementation method, other participating nodes can analyze the block to be added, determine user information, release content, release platform information and release time of a publisher, determine that the message is released in a first communication platform according to the release platform information, acquire a message released by a user account corresponding to the user information at the release time from the first communication platform, determine whether the message is consistent with the release content, if so, indicate that the block to be added is error-free, send a verification result to an information release management platform, perform consensus according to the verification results of the other participating nodes, determine the accuracy of the block to be added, generate a release block according to the block to be added and a user data block chain, and perform uplink on the release block.

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

Specifically, it is detected that the distributed 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 as illegal content according to the illegal message acquisition request; or, obtaining an illegal keyword group contained in the release content, counting the number of the illegal keyword group, determining the sensitive value of the release content according to the number of the illegal keyword group and the sensitive weight corresponding to the illegal keyword group, and if the sensitive value is greater than the parameter threshold, determining the release content as the illegal content. The method comprises the steps of acquiring user information corresponding to front-end equipment before receiving an illegal message acquisition request sent by 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 acquisition request aiming at release content sent by the front-end equipment based on the query key. Since the user information in each block recorded in the information distribution management system contains personal information of the user, the personal information includes real-name information, so privacy protection is needed, and only when the information inquiry authority is provided, the data of each block can be acquired in the information publishing management platform, and specifically, at least one execution process can be set in the intelligent contract, including "if the user information can have the information inquiry authority, then sending the query key to the front-end device corresponding to the user information, and if the received illegal message acquisition request carries the query key, querying the relevant block and feeding the query result back to the front-end device, or after receiving the illegal message acquisition request, directly executing 'if the user information is the recorded user with the information query authority, feeding back the query result to the front-end equipment'.

Because the freedom of publishing the speech on the network is strong, many people can publish their own speech on the network through the virtual account numbers relatively randomly, and can also disclose feelings which cannot be expressed in real life on the network, including gratuitous or malicious speech, and the fact that some users maliciously play a rumor on the network to guide the comments of the masses exists at present, and even if one virtual account number is sealed, a new virtual account number can be reapplied, so that the messages on the network are 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 finds that one of the users XXX is evaluated as the non-actual statement, and sends an illegal message acquisition request according to the release content corresponding to the non-actual statement of the user XXX, and determines the release content as illegal content; or, when the information publishing management system adds the publishing block into the user data block chain, obtaining the publishing content in the publishing block, comparing the publishing content with the illegal keyword library to obtain the illegal keyword groups contained in the publishing content, determining the sensitive value of the publishing content according to the number of the illegal keyword groups and the weight corresponding to each illegal keyword group, and determining the publishing content as the illegal content when the sensitive value is greater than the parameter threshold value so as to realize real-time monitoring on the messages published on the network.

Step S405, at least one query block containing illegal content is obtained, and the broadcast information is obtained according to the encapsulation of the at least one query block.

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 from distribution to propagation of the illegal contents; wherein, the query block recorded in the at least one query block and having the earliest release time includes the propagation source of the illegal content. Or after obtaining at least one query block, obtaining the publishing time in each query block, determining the query block with the earliest publishing time as a target block, and packaging the target block as the propagation information to obtain the propagation source of the published content. The user 1 can issue ' release content ' in the form of ' XX month by XX hour by XX day by X hour, and at least one query block is packaged as the propagation information; optionally, if it is necessary to know a propagation source of an illegal content, the query block with the earliest release time in the at least one query block may be determined as a target block, and the target block is directly encapsulated as propagation information. In an alternative case, for example, if an illegal content is distributed on the network, where the illegal content is related to a reputation damage to another person and has a large influence, the related department needs to solve the distribution of the illegal content from the source, that is, needs to find a ballad, in order to view the related department, the block with the earliest distribution time in the block associated with the illegal content may be directly obtained, and the block with the earliest distribution time is sent to the related department, so that the related department warns or penalizes a user corresponding to the user information recorded in the block. It is considered that, when the number of the at least one query block containing the illegal content is found to be large and the propagation source of the illegal content needs to be known, the process in the optional case may be performed.

Step S406, sending the propagation information to the front-end device.

Specifically, the broadcast information is sent to the front-end device, and the front-end device is a manager with information query authority, optionally, the published content may also be disclosed to inform each user that the published content is illegal. If the transmission information which is required to be packaged is obtained according to the illegal message sent by the front-end equipment, the transmission information is directly sent to the front-end equipment; and if the transmission information encapsulated by the issuing condition of each message is monitored, acquiring the contact information of the manager, and sending the transmission information to the manager.

Optionally, in another possible information distribution management manner, after step S401 to step S402 are executed, when the to-be-added block is verified through the consensus mechanism in step S403, other participating nodes may obtain an illegal keyword group in the distribution content, determine a sensitive value of the distribution content, so as to determine whether the distribution content is an illegal content, if the distribution content is an illegal content, directly execute step S405, determine an inquiry block related to the distribution content, encapsulate the inquiry block as the broadcast information, and send the broadcast information to the front-end device, if the distribution content is not an illegal content, verify through the consensus mechanism, generate a distribution block if the verification is passed, link the distribution block, and end the information distribution management process.

According to the method and the device, the user release information sent by the 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 fact that the release content is illegal is detected, at least one query block containing the illegal content is obtained, the at least one query block is packaged into the spreading information, and the spreading information is sent to the front-end equipment. The information publishing management system is a block chain network, and blocks corresponding to each recorded message are credible and accurate due to the fact that the block chains are not capable of being tampered, so that the published content can be traced when problems occur in the published content, and effectiveness, efficiency and accuracy of information publishing management are improved. When some users issue an utterance and hurt others, the utterance cannot be confirmed immediately, when the utterance is confirmed to be an unreal utterance subsequently, the unreal utterance can be traced back to obtain the issuing and spreading conditions of the unreal utterance, and the management of the unreal utterance is realized through the issuing and spreading conditions of the unreal utterance. Furthermore, the unreal theory can be traced back to obtain the block with the earliest release time so as to determine the release source of the unreal theory, thereby determining the rumor source of the unreal theory and realizing the management of information release from the rumor source. Optionally, a publishing source of each piece of illegal content can be recorded, the publishing source includes real-name information corresponding to user information, if the number of times that a certain real-name user is the publishing source exceeds a preset number of times, the real-name user can be warned, and punishment can be performed seriously, so that management of information publishing is fundamentally realized, and a network environment is managed.
