Detailed Description

The subject matter described herein will be discussed with reference to example embodiments. It should be understood that these embodiments are discussed only to enable those skilled in the art to better understand and thereby implement the subject matter described herein, and are not intended to limit the scope, applicability, or examples set forth in the claims. Changes may be made in the function and arrangement of elements discussed without departing from the scope of the embodiments of the disclosure. Various examples may omit, substitute, or add various procedures or components as needed. In addition, features described with respect to some examples may also be combined in other examples.

As used herein, the term "include" and its variants mean open-ended terms in the sense of "including, but not limited to. The term "based on" means "based at least in part on". The terms "one embodiment" and "an embodiment" mean "at least one embodiment". The term "another embodiment" means "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other definitions, whether explicit or implicit, may be included below. The definition of a term is consistent throughout the specification unless the context clearly dictates otherwise.

Authorization is that a right owner grants the right owned by the right owner to an authorized person for use or operation, and is more commonly IP authorization, and the IP authorization is that a brand owner (or called a copyright party) grants the brand owned by the brand owner or an agent to the authorized person in a form of contract, and the authorized person engages in operation according to the contract and pays a corresponding fee to the copyright party.

For example, after the authorization is completed, the authorized party may use the corresponding IP on the authorized product according to the contractual provisions, for example, printing an IP image on the package of the authorized product. In order to indicate to the consumer that the terminal commodity is an authorized genuine commodity, a widely used method is to paste a paper anti-counterfeiting label on the authorized commodity, and the paper anti-counterfeiting label can be used to prove that the terminal commodity has the genuine authorization quality.

However, the paper anti-counterfeit label needs to be manufactured by a third party and then pasted on the authorized commodity by an authorized party, which not only increases the cost, but also needs to be circulated by multiple parties, resulting in the circulation cost and the unreliability of the circulation process. In addition, the paper anti-counterfeiting label also has the problems of easy counterfeiting and incapability of tracing.

In view of the foregoing, embodiments of the present specification provide an original code generation method and an original code generation apparatus based on a block chain. In the legal copy code generating method, at an authorizing party, after the authorizing party completes authorization to an authorized party, a legal copy code for indicating authorized goods is generated according to authorization information; linking the original code to a block chain, wherein the original code is associated with the authorization information, the legal codes correspond to the authorized commodities one by one; acquiring, at an authorized party, a copyright code from a blockchain; associating the commodity information of the authorized commodity with the legal edition code; the associated scrambling code is linked to the blockchain. In the technical scheme of the embodiment of the specification, the authorized party and the authorized party are associated through the block chain to jointly complete the generation operation of the legal version code, and the participation of a third party is avoided. In addition, the original codes generated each time are linked in the generation process of the original codes, so that the credibility of the generation process of the original codes is ensured, and the non-tamper property and traceability of the original codes are ensured.

The block chain is a distributed shared account book and a database, and has the characteristics of decentralization, no tampering, trace retention, backtracking, openness and transparency and the like. The data on the block chain is stored in the form of data blocks, and the data blocks are connected in time sequence to form a chain data structure. Each block in the chain of blocks is linked to the previous block by an included cryptographic hash, and each block further includes a timestamp, a cryptographic hash, and one or more transactions. The individual transactions in the block form a Merkle tree by hashing. In a Merkle tree, the lowermost leaf node contains the underlying data, each intermediate node is a hash of its child node, the root node is a hash of its child node, representing the root of the Merkle tree, and the root node of the Merkle tree stores hash values representing all the data in the Merkle tree. When verifying whether a hash value is a transaction stored in the Merkle tree, quick verification can be performed by determining whether the hash value is consistent with the structure of the Merkle tree.

A blockchain network is a decentralized point-to-point network consisting of multiple computing nodes for managing, updating, and maintaining one or more blockchain structures. The types of blockchain networks may include public blockchain networks, private blockchain networks, and alliance blockchain networks, depending on the degree of openness of the nodes in the blockchain network.

The public blockchain network is a public network of participating entities, thousands of entities can cooperate in the public blockchain network, each entity operates at least one node in the public blockchain network, and accordingly, the consensus process in the public blockchain network is also completed by each node. In the consensus process, the node participating in the consensus signs the tile to indicate that the node confirms the consensus for the tile, and then the tile that completed the consensus is added to the tile chain of the tile chain network. In addition, the public blockchain network supports public transactions, and the public transactions are shared among all nodes in the public blockchain network and are stored in the global blockchain after being identified by all the nodes. A global blockchain refers to a blockchain that is replicated across all nodes. Consensus in a blockchain network is supported by a consensus mechanism, which is an algorithm for blockchain transactions to achieve distributed consensus, which may include: proof of work (POW), proof of rights (POS), and proof of authority (POA).

The private block chain network only aims at a specific entity, and the read-write permission of each node in the private block chain network is strictly controlled. In addition, the threshold for joining the private blockchain network is high, and permission is required to join the private blockchain network into one node. Based on this, private blockchain networks, also commonly referred to as licensed networks, place restrictions on who is allowed to participate in the network and on the level of participation in the network. For example, some nodes may participate in the uplink process of all transactions, and some nodes may participate in the uplink process of only a designated part of transactions. Various types of access control mechanisms may be used in private blockchain networks, such as voting of adding new entities by existing participants, regulatory agency control permissions, and the like.

The participating entities in the federated blockchain network are also private from each other and can be considered private networks of the participating entities. A federated blockchain network may be composed of several entities, each of which operates at least one node in the federated blockchain network. The consensus process in the federated coalition blockchain network is performed by authorized nodes, which may be all or part of the nodes in the federated coalition blockchain network, each of which signs a block to be uplinked to indicate a consensus acknowledgement for that block, which is then added to the blockchain.

FIG. 1 illustrates a schematic diagram of an example environment 100, according to embodiments of the present description. As shown in fig. 1, the example environment 100 allows entities to participate in a blockchain network 102. The blockchain network 102 may be, for example, a public, private, or alliance chain blockchain network. The example environment 100 may include computing devices 104, 106, 108, 110, 112 and a network 114. In one embodiment, the Network 114 may include a Local Area Network (LAN), a Wide Area Network (WAN), the Internet, or a combination thereof, and is connected to websites, user devices (e.g., computing devices), and backend systems. In an embodiment, the computing devices 104, 106, 108, 110, 112 may access the network 114 through wired and/or wireless communication.

In some cases, the computing devices 106, 108 may be nodes of a cloud computing system (not shown), or each computing device 106, 108 may be a separate cloud computing system, including multiple computers interconnected by a network and operating as a distributed processing system.

In an embodiment, computing devices 104-108 may run any suitable computing system that enables them to act as nodes in blockchain network 102. For example, computing devices 104-108 may include, but are not limited to, servers, desktop computers, laptops, tablet computing devices, and smartphones. In an embodiment, the computing devices 104-108 may be affiliated with a related entity and used to implement a corresponding service, which may be used to manage transactions between an entity or entities, for example.

In one embodiment, each of the computing devices 104-108 stores a corresponding blockchain ledger for the blockchain network 102. The computing device 104 may be (or include) a web server for providing browser functionality that may provide visualization information related to the blockchain network 102 based on the network 114. In some cases, the computing device 104 may not participate in the blockchain verification, but rather monitor the blockchain network 102 to determine when other nodes (e.g., which may include computing devices 106-108) agree, and generate a corresponding blockchain visualization user interface accordingly.

In an embodiment, computing devices 110 and 112 may be client devices connected to blockchain network 102. For example, computing device 110 may be a terminal device at a medical facility platform and computing device 112 may be a terminal device at an advertising administration platform. Computing devices 110 and 112 may include, but are not limited to, servers, desktop computers, laptops, tablet computing devices, and smartphones.

In an embodiment, computing device 104 may receive a request initiated by a client device (e.g., computing device 110 or computing device 112) for a blockchain visualization user interface. In some cases, the nodes of the blockchain network 102 may also act as client devices, such as a user of the computing device 108 may send the request to the computing device 104 using a browser running on the computing device 108.

In response to the request, computing device 104 may generate a blockchain visualization user interface (e.g., a web page) based on the stored blockchain ledger and send the generated blockchain visualization user interface to the requesting client device. If blockchain network 102 is a private type or a federated type blockchain network, the request for the blockchain visual user interface may include user authorization information, which may be verified by computing device 104 before generating and sending the blockchain visual user interface to the requesting client device, and the corresponding blockchain visual user interface returned after verification.

The blockchain visualization user interface may be displayed on the client device (e.g., as may be displayed in user interface 116 shown in fig. 1). When the blockchain ledger is updated, the display content of the user interface 116 may be updated accordingly. Further, user interaction with user interface 116 may result in requests to other user interfaces, such as a search results page that displays a block list, block details, transaction list, transaction details, account list, account details, contract list, contract details, or results of a user conducting a search of the block chain network, and so forth.

Fig. 2 illustrates an example architectural diagram of a blockchain network in accordance with an embodiment of this specification.

As shown in fig. 2, the authorizer 220 is a blockchain node in the blockchain network 214 or a component thereof, and the authorizer 220 may be a node constructed by the authorizer, so that the authorizer can perform data uplink via the authorizer 220 node. The authorizer 220 included in the blockchain network shown in fig. 2 is merely one example. In another example, the authorizer is communicatively connected to a blockchain node in the blockchain network 214. In this example, the authorizer sends the data to be uplinked to the block-link node of the communication connection, which then uplinks the data to be uplinked to the block-link for storage. This can prevent stored data from being deleted or tampered.

The blockchain network 214 also includes an authorized party 240, and the authorized party 240 may be a blockchain link point or a component thereof in the blockchain network 214. In another example, the authorized party 240 is communicatively connected with a blockchain node in the blockchain network 214. In addition, the authorized party 240 may perform a consensus operation with other consensus nodes as the consensus node in the blockchain network 214. The authorized party 240 included in the blockchain network 214 shown in fig. 2 is merely one example.

Further, blockchain network 214 may also include consumer side 260, and consumer side 260 may be a terminal device of each consumer, which may be a blockchain link point in blockchain network 214 or a component thereof, or a device communicatively connected to a blockchain link point. The customer 260 may perform consensus operations with other consensus nodes in the blockchain network 214 as a consensus node. The consumer side 260 included in the blockchain network 214 shown in fig. 2 is merely an example, and in this specification embodiment, the consumer side 260 may not be included in the blockchain network 214.

Fig. 3 shows a flowchart of an example 300 of a block chaining-based plate code generation method according to an embodiment of the present description.

The original code generation method shown in fig. 3 may be performed by both the authorizer and the authorized party, and the authorizer and the authorized party may perform corresponding operations on the blockchain, so that the blockchain may perform full-process recording and uplink on the original code generation method in the embodiment of the present specification. In one example, various operations of the authorizer and authorizee may be controlled and performed by intelligent contracts, each of which may be pre-deployed on a blockchain network.

In the embodiment of the present specification, the authorizing party is a party granted the related right, the authorized party is a party granted the related right, and the authorizing party can grant the right owned by the authorized party to the authorized party for use or operation. The authorized parties may include copyright owners, patentees, and the like, and the authorized parties may include merchants, manufacturers of goods, and the like.

In one example, the authorizer may be an IP authorizer and the authorization information may include information for IP authorization. In this example, the authorizer may be an owner of the IP, the authorizer may grant the owned IP to the authorized party for use, the IP authorization may be in a contractual manner, and the contract may restrict the usage manner, the usage object, the usage scale, the usage period, and the like of the authorized party so that the authorized party may use the IP as specified by the contract. Of course, the authorization addressed by the embodiments of the present specification is not limited to IP authorization, and may also include authorization of other rights such as patents. The following description will take IP authorization as an example.

As shown in fig. 3, at 310, at the authorizer, after the authorizer has completed authorizing the authorized party, a copyright code is generated according to the authorization information; the original code is linked to a block chain.

Before the technical scheme provided by the embodiment of the specification is executed, authorization needs to be completed between an authorizing party and an authorized party. After the authorization is completed, the authorized party can obtain the granted related rights and can use the granted rights according to the agreement of both parties.

After the authorization is completed, both the authorizing party and the authorized party can obtain corresponding authorization information, the authorization information is generated by authorizing the authorized party according to the authorizing party, and the authorization information can include information related to authorization operation between the authorizing party and the authorized party.

In one example, the authorization information may include: identification information of the authorizing party, identification information of the authorized party, authorized transaction information, authorized object information and the like. The identification information of the authorizing party may include a name, a unique identifier, and the like of the authorizing party, and the identification information of the authorized party may include a name, a unique identifier, and the like of the authorized party. The unique identification may include the same social credit code as the authorizing or authorized party of the enterprise, etc. The authorized transaction information may include a transaction contract, transaction ID, and other transaction information for the authorized transaction, among others.

In one example, the authorization object information includes information about an authorization object, the authorization object being an object that is transacted during an authorization transaction, the authorizing party having a right to the authorization object so that the authorizing party can grant the right to the authorized party. For example, if the authorized object is an IP, the object targeted in the IP authorization transaction process is an IP, and the authorized party grants the owned IP to the authorized party. In this example, the authorization object information may include information such as a name, an image, and a type of the authorization object, where the type of the authorization object is a type of a right owned by the authorizer, and the type of the authorization object may include an IP, a patent, and the like. For example, if the authorization object is a cartoon image, the type of authorization object may be IP.

In the embodiment of the present specification, the copyright code may be generated based on the authorization information. The legal copy code can be used for indicating that the authorized commodity belongs to the legal copy, the legal copy code corresponds to the authorized commodity one by one, each legal copy of the authorized commodity has only one legal copy code, and the legal copy codes corresponding to different authorized commodities are different. The presentation form of the legal code may include a two-dimensional code, a one-dimensional code, a character string, and the like. Based on the one-to-one correspondence relationship between the legal codes and the authorized commodities, the authorized party can conveniently control the number of the authorized commodities produced by the authorized party, and the authorized party can be prevented from illegally producing the commodities beyond the authorized number range.

The generated copyright codes are associated with the various authorization information, each authorization information can correspond to a unique copyright code, and each copyright code can be associated with a plurality of authorization information. After the authorization information is associated with the copyright code, the authorization information associated with the legal code can be acquired through the legal code.

In one mode of generating the legal copy code, hash processing may be performed on the authorization information to obtain a corresponding unique code, and the unique code may be used as the legal copy code corresponding to the authorization information.

After generating the scrambling code, the authorizer can uplink the scrambling code to the blockchain.

During the original code uplink, the original code and the corresponding associated authorization information can be recorded in association on the block chain. In one way of associatively recording, the corresponding relationship between the copyright code and the associated authorization information may be established, and the established corresponding relationship may be recorded in the same block on the block chain.

During uplink, the original code and the associated authorization information may be packaged into a block, and then the block is uplink to the blockchain, each blockchain link point in the blockchain network may be used as a common identification node to perform common identification processing on the block to be uplink, and after the common identification is achieved, the block is recorded on the blockchain.

Fig. 4 illustrates a schematic diagram of one example 400 of a consensus process in accordance with embodiments of the present specification. In the example of fig. 4, the accounting node (i.e., master node) is R0, referred to hereinafter as the master node in this example. The determined consensus nodes (i.e., backup nodes) participating in consensus may include R1, R2, and R3, referred to as backup nodes in the following of this example. It should be noted that the consensus process shown in fig. 4, which includes 4 network nodes R0, R1, R2, and R3, is for illustrative purposes only, and the consensus process may include any suitable number of network nodes.

The master node R0 performs a consensus process with all consensus nodes participating in the consensus in the blockchain network, for example, the master node R0 performs the consensus process with the backup nodes R1, R2, and R3.

In the present disclosure, the consensus process may be implemented using PoW (workload proof algorithm), poS (equity proof algorithm), PBFT (practical byzantine fault-tolerant algorithm), and the like. The following description will be made by taking the PBFT consensus process as an example.

As shown in fig. 4, the procedure of the PBFT consensus process includes: a Pre-Prepare phase (Pre-Prepare) 410, a Prepare phase (Prepare) 420, and a confirm phase (Commit) 430.

Specifically, at 410, the master node R0 packages the transaction data to be recorded into the blockchain into a message m, then generates a Pre-prepare message Pre-prepare, and sends (e.g., broadcasts) the Pre-prepare message Pre-prepare to the backup nodes R1, R2, and R3 within a given time interval. The Pre-prepare message Pre-prepare indicates that the master node R0 is initiating the consensus process.

In the present specification embodiment, fig. 5 is a schematic diagram illustrating an example of formats of a pre-preparation message, a preparation message, and an acknowledgement message in a consensus process according to the present specification embodiment. As shown in fig. 5, the format of the Pre-preparation message Pre-prepare may be: < < PRE-PREPARE, epoch, seq, D (m), signature-p >, m, j >. Here, "PRE-PREPARE" denotes a protocol identification of the preliminary preparation message, "epoch" denotes an age of R0 as a master node, "seq" denotes a proposal number of a proposal of a required consensus, "D (m)" denotes a digest of a request message set, "signature-p" denotes a signature of R0, "m" denotes a specific content of the request message (i.e., a specific content of each piece of authentication information in a block), and "j" denotes a node identification of R0. Here, D (m) is obtained by performing hash calculation on each authentication information set in the block.

In the preparation stage 420, for each backup node (R1, R2, or R3), after receiving the Pre-preparation message Pre-preparation and detecting that the Pre-preparation message Pre-preparation is legitimate, the Pre-preparation message Pre-preparation may be stored in a local log and a preparation message preparation for responding to the Pre-preparation message Pre-preparation may be generated and then broadcast to other nodes. The Prepare message Prepare indicates that the backup node has received the Pre-Prepare message Pre-Prepare from the primary node and is sending a reply in response to the Pre-Prepare message Pre-Prepare.

Accordingly, each backup node may also receive the Prepare message Prepare sent by the other backup nodes. Taking backup node R1 as an example, after receiving the Prepare message Pre-Prepare sent by master node R0, backup node R1 broadcasts the generated Prepare message Pre to master node R0, backup nodes R2, and R3. Accordingly, backup node R1 also receives Prepare message Prepare sent by master node R0, backup nodes R2 and R3.

In this illustrative embodiment, the Prepare message Prepare broadcast by the backup node may be used to indicate the consensus commitment made by the backup node during the Prepare phase 420.

In this embodiment, as shown in fig. 5, the format of the preparation message Prepare may be: < PREPARE, epoch, seq, D (m), i, signature-i >. Here, "PREPARE" represents a protocol identifier of the preparation message PREPARE, "i" represents a node identifier of a node that transmits the preparation message PREPARE, and "signature-i" represents a signature of the node that transmits the preparation message PREPARE. The meaning of "epoch", "seq", and "D (m)" in the preparation message Prepare is the same as that of "epoch", "seq", and "D (m)" in the aforementioned preparation message Pre-Prepare.

In the acknowledgement phase 430, when a network node receives a sufficient number of Prepare messages Prepare from other network nodes, the network node determines that consensus has been reached. For example, if primary node R0 or backup node R1, R2, or R3 receives a Quorum (e.g., 2f +1, where f represents the number of failed network nodes) Prepare message Prepare, it is determined that consensus is achieved between the network nodes. The master node R0 or the backup nodes R1, R2 or R3 will then broadcast an acknowledgement message Commit to the other nodes.

In this embodiment, as shown in fig. 5, the format of the acknowledgment message Commit may be: < COMMIT, epoch, seq, D (m), p, signature-p >. Wherein "COMMIT" represents a protocol identification of the acknowledgment message COMMIT, "p" represents a node identification of a node that transmits the acknowledgment message COMMIT, and "signature-p" represents a signature of the node that transmits the acknowledgment message COMMIT. The meaning of "epoch", "seq", and "D (m)" in the acknowledgment message Commit is the same as that of "epoch", "seq", and "D (m)" in the aforementioned prepare message Pre-prepare.

In this illustrative embodiment, a node sends a confirmation message Commit and stores the confirmation message Commit in a local log to represent consensus commitments made by the node during the confirmation phase 430.

Returning to FIG. 3, at 320, at the authorized party, the genuine code may be obtained from the blockchain; associating the commodity information of the authorized commodity with the legal edition code; the associated scrambling code is linked to the blockchain.

After obtaining the legal copy code from the blockchain, the authorized party can associate the commodity information of the authorized commodity with the legal copy code. In this embodiment, the authorized article is an authorized article that can use the authorized object, for example, if the type of the authorized object is IP, the authorized IP can be used on the authorized article. In one example, the type, quantity, and usage of the authorized object of the authorized goods may be agreed in the authorization process, and the authorized party may agree by both parties to use the authorized object on the authorized goods after completing authorization.

In one example, the merchandise information of the authorized merchandise may include at least one of the following information: a product name, a product view, a product link, a product identification, a store name selling authorized products, a store logo, and the like. The commodity view may include at least one basic view of a front view, a top view, a left view, a right view, a bottom view, a rear view, and the like. The merchandise link may include a description link for the authorized merchandise, a link for selling the authorized merchandise, and the like. The commodity identification can be a code for uniquely representing the corresponding authorized commodity, each authorized commodity corresponds to one commodity identification, and the commodity identifications of different authorized commodities can be different.

After the legal plate code is associated with the commodity information of the authorized commodity, the legal plate code can be simultaneously associated with the authorization information and the commodity information, so that the authorization information and the commodity information associated with the legal plate code can be simultaneously acquired through the legal plate code.

After the association between the original code and the merchandise information is successful, the associated original code can be linked to the block chain. After the uplink processing, the legal version code and the associated authorization information and commodity information are recorded in a block of the block chain, and on the block chain, the legal version code and the associated authorization information and commodity information are recorded in the block chain in an associated manner. In one way of the associated recording, a correspondence may be established between the copyright code and the associated authorization information and the merchandise, and the established correspondence may be recorded in the same block on the block chain.

For the uplink mode of the original code at the authorized party, the contents described above with reference to fig. 4 and 5 can be referred to.

The legal version code of the chain on the authorized party can be applied to the corresponding authorized goods, and the application mode can include printing on the package of the corresponding authorized goods, printing on the body of the corresponding authorized goods, and the like. The corresponding authorized commodity can be indicated to the consumer as the authorized genuine commodity through the genuine code.

In an application scenario, the authorized commodity is a high-value solitary commodity, and the unique legal-version code for the authorized commodity can be generated by the legal-version code generation method provided by the embodiment of the specification, and can prove that the authorized commodity is an authorized legal-version commodity, so that counterfeiting and pirating of the authorized commodity are avoided.

By the method for generating the legal version code, the legal version codes corresponding to the authorized commodities one to one are generated and recorded on the block chain, so that the generated legal version codes are prevented from being tampered. The authorization information and the commodity information corresponding to the authorized commodity can be inquired through the unique legal-version code corresponding to the authorized commodity, and the authorized commodity can be proved to be the authorized legal-version commodity through the authorization information and the commodity information. The legal version code generated through the embodiment of the specification ensures the authenticity and verifiability of the authorized goods and avoids counterfeiting and pirating goods.

In one example, after obtaining authorization and generating the authorized product, the authorized party may obtain the authorized product corresponding to the authorized product from the blockchain and associate the authorized product with the authorized product. The manner of association may include printing the proper code on the packaging of the authorized good, printing the proper code on the body of the authorized good, etc. Through the association mode, the consumer can conveniently obtain the legal edition code of the authorized commodity, so that the authorized commodity is confirmed to be the authorized legal commodity through the legal edition code.

In one example, at a consumer purchasing an authorized good, the authorized information and the good information associated with the genuine code may be obtained from the blockchain according to the genuine code.

In one way of obtaining information according to the genuine code, the genuine code may be a two-dimensional code or a one-dimensional code, so that the genuine code may be presented on the authorized goods in the form of the two-dimensional code or the one-dimensional code. The consumer can scan the two-dimensional code or the one-dimensional code on the authorized commodity through the terminal device so as to be connected with the block chain network for recording the legal edition code. Then, the authorization information and the commodity information associated with the recorded legal version code can be acquired from the block chain.

In another way of obtaining information from the legitimate code, the legitimate code may be a string of characters, so that the legitimate code may be presented on the authorized article in the form of a string of characters. The consumer can log in a platform connected with the blockchain network through the terminal device, and then obtains the authorization information and the commodity information associated with the recorded legal version code from the blockchain by inputting the character string of the legal version code on the platform.

After the authorization information and the commodity information associated with the legal-copy code are obtained, whether the authorized commodity is an authorized legal-copy commodity can be checked according to the obtained authorization information and the commodity information.

In one checking mode, whether the authorization information and the commodity information are both accurate can be checked, and when the authorization information and the commodity information are both accurate, the authorized commodity can be determined to be an authorized genuine commodity. When at least one error message exists in the authorization message and the commodity message, the authorized commodity can be determined to be at risk of piracy.

In another verification method, the commodity information recorded on the block chain comprises a commodity identification which is used for identifying a unique code of an authorized commodity. The item identification obtained from the blockchain may be compared to the ID on the authorized item, when the article identification is the same as the ID, it can be determined that the authorized article is an authorized genuine article. When the article identification is different from the ID, it can be determined that the authorized article is at risk of piracy.

Through the above example, the blockchain network can associate an authorizing party, an authorized party and a consumer party, help the authorizing party and the authorized party to establish a connection with the consumer party, and improve the user experience of the consumer party. In addition, the consumer obtains the authorization information and the commodity information associated with the legal-copy code from the block chain, so that the credibility of the authorization information and the commodity information is improved, and the accuracy of the legal-copy inspection result obtained according to the authorization information and the commodity information is improved.

In one example, at a consumer, user information of the consumer may be bound to a copyright code. The user information may include a mobile phone number, a name, a job number, and the like, and the type of the user information bound by the legal code may be specified. Each copyright code is configured to be capable of being bound with user information of one consumer only, and when one copyright code is bound with one user information, the copyright code cannot be bound with other user information. In one example, when the legal code to which one user information is bound also binds other user information, the binding operation cannot be completed, and a binding failure may be prompted.

In a binding mode, the authorized party may operate a member system, and in the member system, the related user information of each consumer as a member and the information of the commodity purchased by each member may be recorded, and the information of the commodity may include a commodity identification, a legal version code, and the like corresponding to the commodity. The consumer can log in the member system through the application program of the terminal device, and corresponding operations are performed in the member system, and the performed operations can include binding operations. Specifically, the consumer can bind own user information with the legal code corresponding to the purchased authorized commodity in the member system, and if the information that the legal code is bound with other user information does not exist in the member system, the binding is successful; if the legal version code is bound with other user information in the member system, the binding is failed.

When the user information of the consumer fails to be bound with the legal code, the authorized goods can be determined to have the piracy risk. When the user information of the consumer is successfully bound with the legal edition code, the authorized commodity can be determined to be the authorized legal edition commodity.

In the above example, each legal code can only bind user information of one consumer, so as to ensure that the legal codes and the authorized commodities are in one-to-one correspondence, and avoid the condition that one legal code corresponds to a plurality of authorized commodities. In addition, through the binding operation, the illegal behavior that one legal code corresponds to a plurality of authorized commodities can be detected, so that the pirate behavior can be timely found and restrained.
