In this embodiment, the digital identity consists of three parts:
the method prefix: the digital snake powder representation method used by DID is specified.
Method specific identifier: a character string consisting of numbers, letters, and dot numbers is used to uniquely identify the owner of the DID or identity information.
DID parameters: an optional string of numbers, letters, and other special characters is used to provide additional information, such as specifying the DID service address or public key.
In addition, random numbers or encryption hash methods are required to be adopted to ensure the security and the non-counterfeitability of the DID when the DID is generated.

step 303: and (5) the binding result is uplink.
In steps 301 to 303, after the authenticity verification of the identity of the holder DID and the authenticity verification of the ownership certificate are completed based on the DID public-private key, a new ownership certificate is issued for the assignee, and the certificate hash and the ownership certificate owner information on the chain are synchronously updated as the ownership certificate number of the original user is the same. The ownership certificate issued by the original user still takes effect after transfer, and the new use authorization is issued after the new ownership certificate is verified by the new assignee user, so that the separation of ownership and use rights is realized.
As can be seen from the above description, the embodiment of the present invention provides a method for processing rights and interests of data works based on blockchains, when each alliance organization builds the alliance chain, each node deploys a blockchain link point and a digital identity service node in the organization, and realizes cross-organization user identity collaboration and security rights and interests guarantee of the data works in binding, authorizing and transferring activities through digital identity DID identification and verifiable credential technology.
In one embodiment, the present invention also provides a method for processing a data work ownership based on a blockchain, which specifically comprises the following steps.
Technical terms:
alliance chain: the business cooperation institutions construct a block chain alliance network according to business requirements, extract business rules as business intelligent contracts and deploy the business intelligent contracts to the block chain alliance network to endorse specific business data.
Blockchain digital identity technology: the method is based on the digital identity identifier of the entity of the blockchain technology and the digital attribute statement verification technology associated with the digital identity identifier, and supports the safe and effective circulation of the verifiable certificates among alliance institutions through a cryptography system associated with the digital identity identifier of the entity. Mainly comprises a distributed digital identity DID and a verifiable digital certificate.
Digital identity DID: unique identification ID of the distributed digital identity. The application comprises the following two aspects: one is a specific instance used to identify DID principals (personnel, organizations, devices, keys, services, and general things); secondly, the creation of persistent encrypted private channel user credential exchange and authentication between entities without any centralized registration mechanism.
Digital certificates may be verified: the certificate refers to the attribute description of the entity, and the verifiable certificate is a tamper-proof certificate signed and encrypted by a publisher, and has the characteristics of cryptographic security and privacy protection. Typically consists of at least two sets of information: one is the verifiable credential itself, containing credential metadata and claims. And secondly, a digital signature of the verifiable certificate.
Firstly, the invention provides a data work ownership processing system based on block chains, which is characterized in that block chain nodes are deployed in each alliance organization, digital identity IDs are registered for users through an organization service system, and the digital identity IDs are bound with real-name identity information of the service system. The business system between alliance institutions authenticates the authority of the user by verifying the identity information credentials of the user. The user of the data work owner uploads the data work and acquires ownership certificates, maintains the use authority of the data work by issuing data work authorization certificates, and completes ownership transfer and use right reservation by issuing new ownership certificates and transfer rights certificates when the data work is transferred. The data work ownership control system based on the blockchain digital identity comprises a service chain 1, a blockchain node 2 and a service system 3.
Referring to FIG. 5, a blockchain-based data work ownership processing system includes: service chain 1, blockchain node 2 and service system 3, in particular:
the service chain 1 is formed by constructing according to the data work circulation requirement of an external service system 3, the chain comprises a plurality of block chain nodes 2, each block chain node structure is consistent, and digital identity service intelligent contracts and data work service intelligent contracts are deployed. The total number of block chain nodes in the service chain is 3f+1, wherein f represents the number of supportable fault-tolerant nodes, and the minimum value is 1. The intelligent contract transaction request adopts a pbft Bayesian busy-tolerant algorithm to carry out consensus, one consensus request can complete consensus after at least 2f+1 consistent confirmation messages from other block chain nodes are received by each block chain node in a service chain, and an execution result can be used as legal data to generate a new block and carry out persistence.
The blockchain node 2 is used for transaction requests initiated by the business system 3, including service requests such as digital identity DID registration, data work binding, data work authorization, data work transfer and the like. And the internal structures of all the blockchain nodes are consistent, authority verification is carried out on the transaction, repetition and parameter validity verification are completed, the transaction is broadcasted to all other blockchain nodes 2 in the service chain 1 after the verification is passed, a consensus transaction request broadcast notice of other blockchain nodes 2 is received, the parameter validity verification is carried out on the consensus transaction, and after the verification is passed, the consensus and account book persistence is carried out, so that the tamper resistance and traceability of all the transactions are ensured.
It should be noted that, the above DID registration is to generate a DID unique identifier for a user, bind a public-private key pair corresponding to the user identity, and link the user's DID and public key information, where the user stores a private key, the private key is used for signing an endorsement of the user identity and a transaction, and the public key user extends a signature.
In addition, the binding of the data works means that the data works of the user are bound with the DID identity of the user, and an ownership data work certificate is issued for the user, and the ownership certificate format is shown in the table 1:
TABLE 1
| Field name | Meaning of field |
| cptname | Ownership credential type identification+credential numbering |
| nftownerdid | Ownership user di identification, i.e. owner of ownership credential |
| orgdid | Institution dididentification of federation organizations to which owner users belong |
| NFTurl | Data work identification information |
| NFThash | DataHash information corresponding to works |
| serverurl | Data work corresponding to data work acquisition address |
| proof | Signature information of private key corresponding to user nftownderdid and organization orgdid on credential field |
The data work authorization is completed by the data work ownership user for the user, and the use right certificate is issued, only the user with the ownership certificate which is not transferred has the authority to issue the use right certificate, and the format of the use right certificate is shown in the table 2:
TABLE 2
Transferring the data works, namely transferring ownership to a new owner, namely an assignee by a current data work ownership user, registering ownership certificates of the transferor as a revocation state on a chain, wherein the transferor no longer has proof certificates for proving the ownership of the data works; meanwhile, a new ownership certificate is issued for the assignee, the assignee becomes an ownership certificate of the data work, the same certificate number is used as the original certificate, and the chain certificate owner dids and the certificate hash are updated.

step S1: component federation service chain.
Specifically, the federation service chain 1 is built by a federation partner authority that needs to participate in the operation of the data work and initialization is completed. Each organization deploys the blockchain node 2 and accesses the blockchain node 2 of its own organization to the guest business system 3 responsible for the operation of the data work. The service chain 1 is initialized and started, the block chain node 2 applies for the corresponding DID digital identity information for each organization to generate a DID identification, the public key is uplink and the private key is returned to the service system, the service system activates the DID identification of the organization to generate a public and private key pair of the service system, the private key is stored by the organization, and the public key is updated to the chain and is associated with the DID identification of the organization.
Step S2: the DID is registered for the user.
The service system 3 calls the digital identity processing device 12 of the blockchain node 2 to register the DID for the organization users participating in the operation activities of the data works of the organization, and the DID is bound with the real-name authentication user information of the users in the service system 3. The DID private key associated with the user DID identifier is stored by the user himself, and public key information is uplink associated with the user DID.
Step S3: binding the data works.
The user can operate the activity through the data works initiated by the business system 3 of the present organization or other alliance organization on the business chain 1, the ownership user of the data works issues own data works through the business system 3, the data work processing device 13 of the blockchain node 2 completes the binding operation of the data works, the unique characteristic of the data works is utilized to verify whether the data works are bound or not during binding, if not, the digital identity processing device 12 is utilized to issue ownership certificates of the data works for the user, the ownership certificate hash is extracted, the unique serial number of the certificate is taken as a main key, and the di information of the certificate hash and the certificate owner is stored on the chain to be taken as the certificate verification basis.
Step S4: and carrying out authorization operation on the data work.
Specifically, the ownership user of the data work performs the authorization of using the data work for the user of the present organization or other alliance organizations on the service chain 1 through the service system 3, the data work processing device 13 completes the authorization operation of the data work, the digital identity processing device 12 is called in the authorization process to verify the identity of the ownership user, the data work processing device 13 is called to verify the ownership certificate of the user, the use right certificate is issued for the user after the verification is passed, the use right certificate hash is extracted, the unique serial number of the certificate is used as a main key, and the certificate hash and the fid information of the certificate owner are stored on the chain to be used as the certificate verification basis. When the user applies for using the data work, the user submits the right-to-use certificate for verification, and the verification passes the available data work.
Step S5: transfer ownership of the data work.
The ownership user of the data works transfers the ownership of the data works for the users of the present organization or other alliance organizations on the service chain 1 through the service system 3, the data work processing device 13 completes the operation of transferring the data works, the digital identity processing device 12 is called to verify the identity of the ownership user in the transferring process, the data work processing device 13 is called to verify the current ownership certificate of the user, after the verification is passed, a new ownership certificate is issued for the assigned user, the ownership certificate hash is extracted, the unique serial number of the certificate is taken as a main key, and the certificate hash and the di information of the certificate owner are updated on the chain to be taken as the certificate verification basis.
Step S6: issuing a right of use credential.
After the ownership transfer of the data works, the ownership certificates of the original users can be invalid because the hash and the fid information of the ownership certificates on the chain are changed in a reverse direction, so that the ownership and the use right authorization rights of the data works are ensured to be safe for the new assigned users. The original user issued right-of-use certificate is still verified to be effective, the right-of-use of the original authorized user is not influenced, but the original user ownership certificate is verified to not issue a new right-of-use certificate. The new assigned user can use the new ownership credential as an authorization authority credential to issue the use right credential for the new user, thereby completing the authorization of the new user.
The data work ownership processing method based on the blockchain solves the problem of cross-organization user identity authentication and circulation control in the related flow of the data work based on the blockchain digital identity DID and the verifiable credential technology. After the user is authenticated by the service system real-name identity, the service system registers the DID for the user, and the DID identifier is used as the binding identity information of the data work to cooperate with the unified identifier of the user identity inter-mechanism interaction to perform inter-mechanism cooperation, and is used as the addressing information of the public key on the user chain to facilitate the user to perform cryptographic authorization and encryption operation. After binding the data work through the digital identity DID, the user issues a data ownership certificate for the data work, the data work is authorized to be used in a mode of issuing an authorization certificate for other users, and the ownership transfer of the data work is completed through the ownership transfer certificate.
