In one embodiment, fig. 1 is a flowchart of a supply chain bill processing method based on a blockchain technology in an embodiment of the present invention, and as shown in fig. 1, there is provided a supply chain bill processing method based on a blockchain technology, including the following steps:
step S110, the block chain receives an issuing request of the supply chain bill, and acquires the bill data and the bill issuing party according to the issuing request. The computer device to which the data owner corresponds may run any suitable computing system that enables it to access the blockchain network as a node in the blockchain network. The computer device may be any electronic device, such as a server, a mobile phone, a computer, a tablet computer, and the like. It will be appreciated that the computer device, when acting as a node of a blockchain network, may communicate with any node on the blockchain network. After receiving the issuing request of the supply chain bill, the block link acquires the bill data in the issuing request and the issuer of the bill. The ticket issuer may be a predetermined interfacing user of a company, an enterprise, etc., for example, when the enterprise user a issues a single supply chain ticket data, the enterprise user a has ownership of the ticket data.
And step S120, adding a bill issuing party in the authority identifier corresponding to the bill data by the block chain, and storing the bill data to the block chain through consensus. After the issued bill data is acquired, the intelligent contract in the block chain manages the bill data according to the preset business management logic. For example, the service data is identified as owned by the enterprise user a and stored to each node of the blockchain through consensus, and the platform side or the blockchain has the storage right of the service data. Optionally, when the ticket data is linked, the authority identifier corresponding to the ticket data is initialized, and a unique identifier of the ticket issuer, such as a public key, is added to the authority identifier and stored in the data authority identifier to identify ownership of the ticket data. In some embodiments, the authority identification may also be used to record the user nodes that are authorized to access during the data access process.
In the process of storing the bill data into the block chain, the block chain is mainly divided into two types of data, namely structured data and unstructured data as the digital information stored in the distributed database. The structured data stores the key index fields of data index information such as serial numbers, dates and times and the like into the intelligent contract according to the structured characteristics, and the evidence storing information irrelevant to the business calculation index can be stored into the transaction information relevant to the current transaction information and the block transaction information. The unstructured data is mainly stored outside a chain in the storage process according to the unstructured characteristics, and the file integrity is endorsed through a block chain. The out-of-chain storage mode can be realized by providing two modes of distributed storage and shared storage. The distributed storage can provide high availability of the unstructured files, the retrieval efficiency of the unstructured data is improved, and the file loss can be greatly saved by shared storage.
By the supply chain bill processing method based on the blockchain technology, once the supply chain bill data is stored in the blockchain, tampering and revocation operations cannot be performed, and based on the data storage specification of the distributed account book, when a certain node encounters a network problem, a hardware fault or is attacked, the operation of the whole system of other nodes cannot be influenced. In the block chain network, each participating node needs to follow the same accounting rule which is performed based on a cryptographic algorithm and codes instead of a traditional trust mechanism, so that the system does not need to depend on a centralized mechanism, and the continuity and reliability of the supply chain bill system are improved.
In one embodiment, fig. 2 is a flow chart of encryption in a supply chain ticket processing method based on the block chain technology in an embodiment of the present invention, and as shown in fig. 2, after receiving an issuance request of a supply chain ticket and acquiring ticket data and a ticket issuer according to the issuance request, the method further includes:
in step S210, the block chain generates and stores an encryption key, and sends the encryption key to the ticket issuing party. Optionally, a cryptographic contract is included in the smart contracts in the blockchain, the cryptographic contract being used to randomly generate an irreversible cryptographic key for distribution to the user. And after encrypting the bill data by using the encryption key, the user calls the service contract to carry out service data chaining.
Step S220, receiving the ticket data encrypted by the encryption key, adding a ticket issuing party to the authority identifier corresponding to the ticket data, and storing the ticket data in the block chain by consensus. The bill data encryption comprises symmetric encryption and asymmetric encryption, wherein the symmetric encryption refers to encryption by using a secret key and decryption by using the same secret key. The symmetric encryption uses the scenes of encrypting data and inquiring the encrypted data by a data owner, a secret key is generated by a specific encryption contract, the secret key is invisible, and a bill issuer in a supply chain bill system calls a service contract to encrypt the bill data by using the secret key and then stores the bill data in a contract account book. When the subsequent data owner inquires the data, the data plaintext is returned to the data owner after the contract is decrypted by the symmetric key. Asymmetric encryption refers to that a pair of public and private keys is encrypted by the public key and then decrypted by the private key, and the asymmetric encryption is used in a point-to-point data authorization query scene. All transaction data in the system can be encrypted, and the ownership of the data is owned by a data producer, namely a bill issuer, so that the privacy of supply chain bills can be improved.
In one embodiment, fig. 3 is a flowchart of data authorization in a supply chain bill processing method based on the blockchain technology according to an embodiment of the present invention, and after the bill data is stored on the blockchain by consensus, as shown in fig. 3, the method further includes:
step S310, receiving the authorization request, and determining the bill data and the bill user corresponding to the authorization request. The data issuer can perform access authorization on the bill data as an owner of the bill data, the block link receives an authorization request of the data issuer, and the authorized bill data and the bill user are confirmed according to the authorization request.
And step S320, adding a ticket user in the authority identifier corresponding to the ticket data. After determining the management bill using party, the blockchain adds the bill using party in the authority identification corresponding to the authorized cheating data, wherein the bill using party comprises a supply chain bill signing party, a supply chain bill forwarding party and a supply chain bill inquiring party.
In steps S310 to S320, after the data is linked, the ticket issuer may dynamically maintain the authority list of the data, add or delete the data authority, and optionally, may also set the time limit of the data authority, and dynamically modify the authority of the data. Optionally, asymmetric encryption may be used in the data authorization query scenario, and at the business system level, the encrypted data stored in the contract ledger by the user a is authorized to be viewed by the user B. On the corresponding technical implementation level, the contract stores the public key of the user B into a user authorization list corresponding to the data, when the user B initiates data query operation, the contract decrypts the encrypted data symmetrically, the public key of the user B is used for encryption and then returns the encrypted data to the user B, and the user B uses the private key of the user B for decryption and then obtains the data plaintext. The asymmetric encryption ensures that the data can be decrypted only by using the corresponding private key after being encrypted by the public key, thereby ensuring the data security. The issuing party of the bill has the ownership of the bill, and the processes of signing and inquiring the bill and the like have authorized authority, so that the privacy protection can be better performed on the bill.
In one embodiment, before receiving the request for authorization from the ticket issuer, the method further comprises: receiving an authority request, determining bill data corresponding to the authority request, and acquiring an authority identifier corresponding to the bill data; and the bill issuing party acquires the bill data according to the authority identifier and sends an authority request to the bill issuing party. In this embodiment, the ticket user can make an authority request for the supply chain ticket according to the requirement, optionally, the intelligent contract on the block chain can perform identity verification on the ticket user, then accept the authority request of the ticket user, determine the requested ticket data according to the authority request, and obtain the authority identifier corresponding to the ticket data, so that the issuer of the ticket data can be determined, and thus send the authority request to the ticket issuer, and the ticket issuer can send the authorization request according to the authority request. In the implementation, besides the active authorization of the bill issuing party, the bill using party can also make a permission request according to the use requirement of the bill using party, so that the permission management of the supply chain bills is more flexible.
In one embodiment, fig. 4 is a flowchart of data usage in a supply chain ticket processing method based on the blockchain technology in an embodiment of the present invention, and as shown in fig. 4, after adding a ticket user to a rights identifier corresponding to the ticket data, the method further includes:
step S410, receiving a use request of the supply chain bill, determining bill data and a data requester corresponding to the use request, and acquiring an authority identifier corresponding to the bill data. The use request comprises a bill signing request, a bill circulation request, a bill pasting request and a bill query request. The block link ticket receiving method comprises the steps that a user uses a use request of a ticket user, such as a supplier, a depository institution, a security company, a bank and the like, ticket data which need to be inquired or used by the ticket user and the requester are determined, and authority identification corresponding to the ticket data is obtained.
Step S420, feeding back the ticket data to the data requester when the authority identifier includes the data requester. And inquiring whether the authority identifier corresponding to the bill data comprises a user, if so, indicating that the data requester has the authority to inquire and use the bill data, and feeding the bill data back to the requester by the block chain.
Through steps S410 to S420, the blockchain may manage the query and use process of the ticket data according to the authority identifier, and optionally, the authority identifier of the intelligent contract may be subdivided into three data modules: data ID, user ID, token. The mapping relation of the three is a forward tree model, and structured information such as index and ID of the privacy-protected bill data is recorded in the data ID; the user ID records a user list which has the right to access the bill data, and account information related to the user is in the list; the token records the access authority range of the user ID to the ticket data, such as the access period, the access times, the data range and other information. The three-layer data model is used for protecting the private data, so that the private data can be maintained and updated in real time, and the authority management and the privacy protection of the bill data are improved.
In some embodiments, the blockchain is a blockchain private chain or a blockchain alliance, so that a corresponding principal of the blockchain network node, such as a computer device, needs to complete registration on the blockchain platform in advance, and obtain a corresponding public key and a corresponding private key as identity information for performing identity authentication. When acquiring a request for issuing a bill of a supply chain, a block chain firstly determines that the identity of a bill issuing party is credible and then allows the bill issuing party to develop the related business for issuing the bill. Optionally, the above-mentioned authentication process may also be used for authentication of each supply chain bill participant, for example, a preset supply chain bill circulation participant is established through an intelligent contract, only the preset participant can participate in the circulation flow of the supply chain bill through authentication. The safety of the supply chain bills and the circulation process thereof is improved.
According to another aspect of the present invention, fig. 5 is a schematic structural diagram of a supply chain bill processing system based on a block chain technology according to an embodiment of the present invention, and as shown in fig. 5, the system includes a contract layer 52 and a data storage layer 54, the intelligent contract layer is configured to receive an issuance request of a supply chain bill, obtain bill data and a bill issuer according to the issuance request, add an authority identifier corresponding to the bill issuer to the bill data, and the data storage layer is configured to store the bill data on a block chain through consensus.

For specific definition of the supply chain bill processing system based on the blockchain technology, reference may also be made to the above definition of the supply chain bill processing method based on the blockchain technology, and details are not described here again. The various modules in the supply chain note processing system based on block chain technology described above may be implemented in whole or in part by software, hardware, and combinations thereof. The modules can be embedded in a hardware form or independent from a processor in the computer device, and can also be stored in a memory in the computer device in a software form, so that the processor can call and execute operations corresponding to the modules.
In a preferred embodiment, FIG. 6 is a schematic diagram of a blockchain technology-based supply chain document processing system in accordance with a preferred embodiment of the present invention, as shown in FIG. 6, including an intelligent contract layer 62 and a data store layer 64.

The meaning chain upgrades the traditional data storage into distributed storage, and simultaneously, based on the encrypted storage and the non-tamper property of the bottom layer of the block chain, the requirements of ensuring data authenticity, data privacy protection, data tracing and high-efficiency data synchronization in different business systems are met.
The intelligent contract layer includes various contract types such as cryptographic contracts, business contracts, ledger encryption, data encryption and decryption, data authorization and the like. The encryption contract is used to randomly generate an irreversible encryption key for distribution to the user. And after the user encrypts the data by using the encryption key, calling the service contract to carry out service data chaining. The service contract is used for presetting rules in advance according to different service logics, and comprises the management of a user key, the service logic processing, the mapping of contract data and information on a chain and the like. The account book encryption is used for starting encryption configuration on the account book when the intelligent contract account book is initialized. The data encryption and decryption contract comprises symmetric encryption and decryption and asymmetric encryption and decryption. The data grant is used for data uplink time grant and data link dynamic grant. The authorization during data uplink refers to initializing a permission list of data during data uplink, and storing unique identifiers of all data authorizers in the data permission list to limit access permissions of the data. The dynamic authorization on the data link refers to that after the data is linked, a permission list of the data can be dynamically maintained, a data permission party is added or deleted, and the time effectiveness of the data permission can be set to dynamically modify the data permission.
The data storage layer is used for storing structured data storage and unstructured data storage, and the storage mode is different due to different data types. The structured data stores key index fields of data index information such as serial numbers, date and time, service key information and the like into the intelligent contract according to the structured characteristics, and the evidence storing information irrelevant to the service calculation index can be stored into the transaction information relevant to the current transaction information and the block transaction information. The unstructured data is mainly stored outside a chain in the storage process according to the unstructured characteristics, and the file integrity is endorsed through a block chain. The out-of-chain storage mode can be realized by providing two modes of distributed storage and shared storage. The distributed storage can provide high availability of the unstructured files and improve the retrieval efficiency of the unstructured data. And file loss can be greatly saved by sharing storage.
