The blockchain network is a distributed application architecture for distributing tasks and workloads among peers, and is a networking or network form formed by peer-to-peer computing models in an application layer. Generally, a blockchain network includes a plurality of computers connected to each other, and these computers are also called node devices of the blockchain network. In a blockchain network environment, a plurality of computers connected with each other are in an equivalent position, each computer has the same function and is not divided into a master computer and a slave computer, and one computer can be used as a server to set shared resources for other computers in the network to use; the network as a whole generally does not rely on a dedicated centralized server, and there are no dedicated workstations. Each computer in the network can both act as a requester of network services and provide resources, services and content in response to requests from other computers.
FIG. 1 illustrates an architecture diagram of a data processing system provided by an exemplary embodiment of the present application. As shown in fig. 1, the data processing system may include an authorizing device 101, an authorized device 102, and a plurality of node devices 103 in a blockchain network. The number and form of the devices in the data processing system shown in FIG. 1 are for example and do not constitute a limitation of the present application. For example: the number of authorized devices and authorized devices may be multiple, the number of node devices is determined by the actual networking structure of the blockchain network, and may be more than or equal to 3, and the application does not limit the number of devices.
The authorizing device 101 is a device used by a first user (i.e., the work owner) and may include, but is not limited to: smart phones (such as Android phones and iOS phones), tablet computers, portable personal computers, Mobile Internet Devices (MID), and the like, which are not limited in the embodiments of the present invention.
Authorized device 102 is a device used by a second user (i.e., a work authorization object), which may include, but is not limited to: smart phones (such as Android phones, iOS phones, and the like), tablet computers, portable personal computers, MID, and the like, which are not limited in the embodiments of the present invention.
The node device 103 in the blockchain network may specifically be a client or a server, which is not limited in this embodiment of the present application. Wherein, the client can be any one of the following: a terminal, a standalone Application, an Application Programming Interface (API), or a Software Development Kit (SDK). Among others, the terminal may include but is not limited to: smart phones (such as Android phones, iOS phones, and the like), tablet computers, portable personal computers, MID, and the like, which are not limited in the embodiments of the present invention. The type of node device may include, but is not limited to, a full node, a Simple Payment Verification (SPV) node, or other node types in a blockchain network. The full node is a node storing a complete block chain, can independently check all transactions on the block chain and update data in real time, and is mainly responsible for broadcasting and verifying the transactions of the block chain. A full node is typically a high performance computing device. SPV nodes may also be referred to as lightweight nodes. An SPV node is a node that stores only a portion of a blockchain; for example, the SPV node stores only all the block header information and the block information related to the self information in the block chain, and does not store the complete block chain. SPV nodes are nodes that rely on the existence of full nodes and do not provide computing power for blockchain networks. Therefore, the SPV nodes are mostly mobile terminals, such as smart phones, tablet computers, or mobile computers.
In one embodiment, the authorizing device 101 may be deployed in a blockchain network, i.e., the authorizing device may be a node device in the blockchain network. In another embodiment, the authorized device may be a device outside the blockchain network, which may be connected to a node device in the blockchain network for data communication. Similarly, the authorized device 102 may also be deployed in the blockchain network as a node device in the blockchain network; alternatively, the authorized device may be a device outside the blockchain network that may be in data communication with a node device in the blockchain network.
In this embodiment, a first user may send authorization information to a node device in a blockchain network through an authorization device 101, where the authorization information is used to instruct the first user to authorize the second user the usage right of a target work set. Under the condition that the node equipment receives the authorization information, transaction data can be generated according to the authorization information and stored in the blockchain network, so that the blockchain network can know that the first user authorizes the use right of the target work set to the second user. The authorization of the works is applied to the block chain network, so that the repeated authorization of the use rights of the works can be effectively prevented.
In order to enable a first user to transfer the usage right of a work to a second user while maintaining the ownership of the work, the embodiment of the present application provides a data processing method, which is described in detail below.
Fig. 2 is a flowchart of a data processing method according to an exemplary embodiment of the present application. As shown in fig. 2, the data processing method includes, but is not limited to, the following steps 201 to 203. Wherein:
201. the first user sends authorization information to the node device through the authorization device. Accordingly, the node device receives authorization information of the first user.
Wherein the first user is an owner or originator of the set of target works. Wherein the set of target works may be any set of works authored by the first user. A set of target works may include one or more works, with the same set of target works including works based on the same concept or belonging to the same series. For example, in the music piece set, the music piece 1 is background music, the written work 1 is lyrics corresponding to the music piece 1, and the music piece 2 is a music piece combining the background music and the lyrics. For another example, in the article collection, article 1 and article 2 are the same series of articles, and article 2 is a continuation of article 1.
The authorization information includes the target token and information of the second user. Tokens (tokens) can provide proof of authenticity for corresponding objects (e.g., digital assets, transaction information, etc.) and prevent third parties from modifying the data. The target token is used to indicate an object having ownership over the set of target works, and may be understood to indicate the originator of the set of target works. Specifically, the object mapped by the target token has the usage right of the work set corresponding to the target token. For example, the collection of works corresponding to the token 1 is a painting collection 1, the painting collection 1 includes a painting 1 and a painting 2, an owner or originator of the painting collection 1 is the user 1, that is, the user 1 has ownership of the painting collection 1; assuming that the object mapped by token 1 is user 2, it indicates that user 2 has the right to use drawing 1 and drawing 2. The second user is a mapping object of the target token in the authorization information (i.e. an authorization object of the usage rights). The information of the second user includes, but is not limited to, an address of the second user and identification information of the second user. The identity information can be a public key of the second user; the address may be an Internet Protocol (IP) address or a Media Access Control (MAC) address of an authorized device used by the second user, or the like.
Optionally, the authorization information further includes information of the first user, and the information of the first user may include, but is not limited to, an address and a public key of the first user. The information of the first user can be used for the node equipment to verify whether the first user is a legal user.
Assuming that the first user wants to authorize the right to use the work set 1 to the second user, the first user needs to send authorization information including the target token corresponding to the work set 1 and the information of the second user to the node device in the blockchain network.
The first user sends authorization information to the node device, which can be understood as a transaction in the blockchain network, and the node device receives the authorization information and can verify whether the transaction is legal or not according to the public key of the first user. Specifically, the node device performs hash calculation on the authorization information by using a hash algorithm to obtain a first digest, decrypts the digest of the authorization information sent by the first user by using a public key of the first user to obtain a second digest, and if the first digest is the same as the second digest, the authorization information is legal, otherwise, the authorization information is not legal. The first user adopts a Hash algorithm to carry out Hash calculation on the authorization information to obtain an abstract, and a private key of the first user is adopted to encrypt the abstract to obtain the abstract of the authorization information. The digest of the authorization information may be sent to the node device along with the authorization information. The node device and the first user adopt the same hash algorithm. And executing the step 202 when the node device determines that the authorization information has validity, otherwise, discarding the authorization information, and sending prompt information of validity verification failure to the first user.
202. And the node equipment maps the target token to the information of the second user according to the authorization information to generate transaction data.
The transaction data is used for recording the usage right authorization relation of the work set corresponding to the target token, and specifically includes information of a first user, information of a second user and the target token. In this embodiment, the authorization relationship is that the first user authorizes the usage right of the work set corresponding to the target token to the second user. And the node equipment maps the target token to the information of the second user according to the authorization information, and the use right of the work set corresponding to the target token is authorized to the second user. Specific implementations may include, but are not limited to: the target token is mapped to an address of the second user.
203. The node device stores the transaction data into the blockchain network.
In one embodiment, the node device stores the transaction data in the blockchain network, which is performed by the node device in the blockchain network for consensus, and if the blockchain network achieves consensus, the node device stores the transaction data in the blockchain network, that is, a block is generated according to the transaction data and added to the blockchain account book. The node device sends indication information to other node devices in the blockchain network, wherein the indication information is used for indicating the operation of storing the transaction data into the blockchain network, and if more than half of the node devices in the blockchain network approve the operation, the blockchain network achieves consensus. And if the block chain network does not achieve the consensus, sending a prompt message of the failure of the consensus to the first user.
In one embodiment, the node device transmits the transaction data to other node devices in the blockchain network. The other node devices can authorize the first user to authorize the usage right of the target work set corresponding to the target token to the second user according to the transaction data to verify the transaction. And other nodes send the verified result to the blockchain network, if the verified result of more than half of the node devices in the blockchain network passes, the nodes in the blockchain network achieve consensus, store the transaction data, and send prompt information of successful authorization to the first user and the second user. And if the verification results of more than half of the node devices in the blockchain network are failed, the nodes in the blockchain do not reach the consensus, the transaction data are not stored, and prompt information of consensus failure is sent to the first user.
In the embodiment of the application, node equipment in the block chain network receives authorization information of a first user, maps a target token to information of a second user according to the authorization information, generates transaction data, and stores the transaction data in the block chain network. Therefore, the target token is mapped to the information of the second user, so that the first user can transfer the usage right of the work to the second user under the condition that the ownership of the work is reserved.
Fig. 3 is a flowchart of another data processing method according to an exemplary embodiment of the present application. The data processing method can be realized by interaction between the authorization device 101 and the node device 103 shown in fig. 1; as shown in fig. 3, the data processing method includes, but is not limited to, the following steps 301 to 305. Wherein:
301. and the first user sends the information of the target work set and the certification message of the target work set to the node equipment through the authorization equipment. Correspondingly, the node equipment receives the information of the target work set of the first user and the certification information of the target work set.
The target work set is a work set with ownership of the first user, and the target work set comprises at least one work. Specifically, works may include, but are not limited to, paintings, design drawings, articles, audio, video, etc. intellectual works that are original in nature and are expressed in a tangible form. The information of the target work set includes the individual works in the target work set. For example, the information of the piece set 1 includes a musical piece 1 and a musical piece 2, and the musical piece 2 may be an improvement of the musical piece 1. The certification information of the target work set is used for certifying the target work set, and may include, but is not limited to: time of creation of the work, type of the work, description, concept, idea of creation, and the like. It will be appreciated that the certification information for the target work collection is used to describe information that the first user authored the target work collection, such as by authoring ideas to describe the target work collection.
In one embodiment, the node device performs hash calculation on the certification information of the target work set by using a hash algorithm to obtain a first hash value when receiving the information of the target work set and the certification information of the target work set of the first user. And then, decrypting the abstract of the certification information by adopting the public key of the first user to obtain decrypted information, and calculating the decrypted information to obtain a verification hash value. The first user adopts a Hash algorithm to carry out Hash calculation on the certification information to obtain an abstract, and adopts a private key of the first user to encrypt the abstract to obtain the abstract of the certification information. The digest of the attestation information may be sent to the node device along with the attestation information. And the node equipment checks and verifies whether the hash value is consistent with the first hash value. If the hash value is consistent with the first hash value, the verification is passed, and step 302 is continuously executed. And if the verification hash value is inconsistent with the first hash value, the verification fails, and prompt information of verification failure is sent to the first user.
302. And the node equipment establishes the association relation between the information of the target work set and the target evidence storing identification according to the evidence information of the target work set.
The target evidence storing identification is used for associating the target work set of the first user, and at least one corresponding target work can be determined through the target evidence storing identification. It can be understood that the target deposit certificate identification has a corresponding relationship with the target work set, and also has a corresponding relationship with the target work included in the target work set.
In one embodiment, each time a collection of works is received, a node device may generate a corresponding LC identifier. The target certificate of credit identification is a certificate of credit identification allocated to the target work set by the node device. For example, assume that a musical piece 1 and a musical piece 2 are included in a piece set 1. After receiving the work set 1, the node device generates a certificate storing identification 1, and associates the musical works 1 and 2 together according to the certificate storing identification 1.
In another embodiment, the target certificate identity has an association relationship with the first hash value, for example, the target certificate identity is the same as the first hash value, or the target certificate identity is obtained by performing a mathematical operation on the basis of the first hash value, and so on. It can be understood that the target work set associated with the target deposit certificate identifier is the same as the target work set corresponding to the certificate information of the target work set.
Optionally, the node device may associate each work in the target work set with the target deposit certificate identifier according to the certification information of the target work set. Specifically, each work in the target work set may be associated to the target deposit evidence identifier by the work creation time, the work category, and the like. For example, the proof identifier 1 has associated therein the musical piece 1 and the musical piece 2 created by the user 1, and the pieces corresponding to the proof information 1 are also the musical piece 1 and the musical piece 2 created by the user 1. Then, the node device receives the musical piece 3 created by the user 1, where the musical piece 3 is a combination of the musical piece 1 and the musical piece 2 (i.e., based on the same concept), and the node device may associate the musical piece 3 to the voucher identification 1.
In one embodiment, the node device performs hash calculation on the works in the target work set to obtain second hash values corresponding to the works, and then the node device associates the second hash values corresponding to the works based on the same creation thought to the target deposit evidence identifier through the work creation thought recorded in the certification information of the target work set. For example, the information of the first target work set of the first user includes musical works 1 and musical works 2, and the node device associates the hash value corresponding to the musical works 1 and the hash value corresponding to the musical works 2 to the first target evidence storing identification according to the certification information of the first target work set. The information of the second target work set of the first user comprises article work 1 and article work 2, the node device stores the hash value corresponding to the article work 1 and the hash value corresponding to the article work 2 into a second target evidence storing identification according to the certification information of the second target work set, namely, the article work 1 and the article work 2 are associated through the second target evidence storing identification.
303. And the node equipment stores the information of the target work set and the target certificate storing identification into the block chain network.
In one embodiment, the node device sends the information of the target work set and the target certificate of credit identification to other node devices in the blockchain network. And the other nodes verify whether the information of the target work set is matched with the target evidence storing identification, send the verified result to the block chain network, if the verification results of more than half of the node devices in the block chain network are matched, store the information of the target work set and the target evidence storing identification, and continue to execute the step 304. And if the verification results of more than half of the node devices in the block chain network are not matched, not storing the information of the target work set and the target evidence storing identification, and sending a prompt message that the information of the target work set is wrongly associated with the target evidence storing identification to the first user.
304. And the node equipment distributes a target token for the target certificate storage identification.
In one embodiment, the node device allocates a corresponding target token to the target credit identification according to an intelligent contract preset in the block chain network. At this time, the address of the newly allocated target token map is the information of the owner of the target work set corresponding to the target deposit certificate identifier, and in this embodiment, the address of the newly allocated target token map is the information of the first user.
Optionally, the address of the newly allocated target token map may also be null, that is, other users do not have the right to use the target work set except the owner of the target work set.
305. And the node equipment sends the target token and the target certificate storing identification to the first user.
The target token may be used when the first user needs to authorize the usage right of the target work set corresponding to the target token to other users, and a specific implementation method is the same as the data processing method described in fig. 2, and is not described here again. It will be appreciated that steps 301-305 are performed prior to step 201 in the embodiment shown in fig. 2.
The target deposit certificate identification may be used when the first user needs to add a new work to the target work set associated with the target deposit certificate identification. In one implementation, the first user sends information of the newly added work and the evidence storing identification to the node device. And the node equipment receives the information of the newly added works and the evidence storage identification sent by the first user. And the work corresponding to the evidence storing identification is the work which is expected to be associated with the newly added work. For example, the first user has sent article work 1 and article work 2 to the node device, and received the deposit certificate identifier 1 sent by the node device and corresponding to article work 1 and article work 2. Then, the first user wants to associate the newly added article 3 with the article 1 and the article 2, and the article 3, the article 1 and the article 2 may be articles based on the same concept. For example, article work 3 may be a continuation of article work 1 and article work 2. The first user sends article works 3 and evidence storage identification 1 to the node device. After receiving the article works 3 and the evidence storing identification 1 sent by the first user, the node equipment determines a corresponding work set according to the evidence storing identification 1 and stores the article works 3 into the work set.
It can be seen that, the embodiment of the present application adds a process of storing the work to the blockchain network by the first user on the basis of fig. 2. The evidence storing identification is generated in the process of storing the works, and the works of the first user can be associated according to requirements (such as classified management according to types, creation time and the like) through the evidence storing identification; and adding the newly added works into the associated work group according to the certificate storage identification. In addition, the work is subjected to hash calculation, and the obtained hash value is stored in the certificate storing identification. Compared with the mode that works are directly stored in the certificate storing identification, the storage space of the node equipment can be saved by only storing the hash value of the works.
Fig. 4 is a flowchart of another data processing method according to an exemplary embodiment of the present application. The data processing method can be realized by interaction among the authorization device 101, the authorized device 102 and the node device 103 shown in fig. 1; as shown in fig. 4, the data processing method includes, but is not limited to, the following steps 401 to 407. Wherein:
401. the first user sends authorization information to the node device through the authorization device. Accordingly, the node device receives authorization information of the first user.
The specific implementation of step 401 is the same as that in step 201 of fig. 2, and is not described herein again.
402. And the node equipment searches whether an authorization relation corresponding to the target work set exists or not according to the target token.
In one embodiment, the node device looks up and determines whether the address mapped by the target token is the first user's information or is null. If the address mapped by the target token is the information of the first user or is null, it is determined that the target work set does not have an authorization relationship, and step 403 is continuously executed. If the address mapped by the target token is the information of other users except the first user, it is determined that the target work set does not have an authorization relationship, and step 405 is continuously executed.
403. And the node equipment determines that the target work set does not have an authorization relation, maps the target token to the information of the second user according to the authorization information and generates transaction data.
404. The node device stores the transaction data into the blockchain network.
The specific implementation of steps 403 to 404 is the same as that of steps 202 to 203 in fig. 2, and is not described herein again.
405. And the node equipment determines that the target work set has an authorization relation and generates prompt information.
Wherein the prompt message is used to prompt that the usage right of the target work set is authorized to other users except the first user and the second user. For example, the authorization information sent by the user 1 to the node device includes information of the token 1 and the user 2. I.e. the user 2 is granted the right to use the collection of works corresponding to the token 1. And the address mapped in the token 1 is the information of the user 3, namely the usage right of the work set corresponding to the token 1 is authorized to the user 3. At this time, the node apparatus generates a prompt message for prompting that the usage right of the work set corresponding to the token 1 has been granted to the user 3 by the user 1 and the user 2.
Optionally, the node device may add information of the user currently owning the usage right of the target work set (i.e., information of the object mapped by the target token) to the hint information, so that the first user and the second user may negotiate with the user currently owning the usage right of the target work set with respect to the usage right of the target work set.
406. The node device sends a prompt message to the authorization device.
407. The node device sends a prompt message to the authorized device.
It should be noted that step 407 may be executed simultaneously with step 406, or may be executed before or after step 406.
Therefore, on the basis of fig. 2, the embodiment of the application verifies whether the usage right of the target work set is authorized to the first user and other users outside the second user through the target token, so that the situation that the first user repeatedly authorizes the same work set is avoided.
In an optional implementation manner, the node device receives information of a work to be checked, wherein the work to be checked is a work which needs to be queried whether the work is authorized. The information of the work to be checked may be transmitted by the first user or may be transmitted by the second user. The node equipment calculates the hash value of the work to be checked through a hash algorithm, and searches and confirms whether the corresponding certificate storing identification exists through the hash value. And if the corresponding evidence storing identification does not exist, the checked work is not disclosed in the block chain network. And if the corresponding certificate storing identification exists, searching and confirming the corresponding token through the corresponding certificate storing identification. And the node equipment searches and confirms whether the transaction data corresponding to the target token exists in the block chain network or not according to the target token. If the transaction data corresponding to the target token exists, the authorization relationship of the target work set already exists (namely the use right of the target work set is authorized to other users except the first user and the second user). And the node equipment sends prompt information to the first user and the second user, wherein the prompt information is used for prompting that the target work set of the first user and the second user is authorized to other users except the first user and the second user. If there is no transaction data corresponding to the target token, then usage rights indicating the set of target works may be granted to the second user.
