Detailed Description

The following description of the exemplary embodiments of the present application, taken in conjunction with the accompanying drawings, includes various details of the embodiments of the application for the understanding of the same, which are to be considered exemplary only. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present application. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.

For convenience in explaining the embodiment of the present application, fig. 1 shows, as an example, an interaction diagram between an electronic license platform and an electronic license block chain network, which are applicable to the embodiment of the present application, and fig. 2 shows, as an example, an interaction diagram between an authorization and authentication platform and an electronic license block chain network, which are applicable to the embodiment of the present application, but are not to be construed as specifically limiting the embodiment of the present application.

As shown in fig. 1, the electronic license platform may include an electronic license issuing service system, an electronic license management service system, and an electronic license database as a software platform. The electronic certificate issuing service system and the electronic certificate management service system can be arranged on a plurality of light-weight nodes or a plurality of full nodes, and can be arranged on the light-weight nodes generally. The light-weight node is also deployed with regular data of the blockchain, can access the blockchain, but is limited by hardware capability, and is generally only responsible for completing functions of part of the blockchain and storing part of data, while the whole node is responsible for completing all functions of the blockchain and storing all data. The lightweight node and the full node have different functions, and in the embodiment of the present application, the functions are preferably embodied as: the lightweight node is responsible for initiating the transaction request, but may not be responsible for verifying the transaction requests initiated by other nodes; the whole node can initiate the transaction request, can also verify the transaction requests initiated by other nodes, and has the function of packaging out blocks. The lightweight node can select at least one trusted full node to be associated with, and incomplete functions or data which is not stored in the lightweight node can request the trusted full node to complete in an auxiliary mode. The lightweight nodes and the full nodes can form an electronic certificate alliance chain. Each certificate authority may maintain its own node device.

The staff of each certificate authority can write the electronic certificate data generated in the processes, uses and other links related in the whole life cycle of the electronic certificate into an electronic certificate database by using a certificate issuing business system or an electronic certificate management business system, for example, the links of submitting materials, checking materials, passing an approval, discharging certificates, using certificates and the like, and sends the electronic certificate data to an electronic certificate block chain network to realize cochain storage. The electronic license data in the embodiment of the application comprises the electronic license content and the processing operation information related to the electronic license. The electronic certificate database can be arranged on a plurality of full nodes and used for storing electronic certificate data written in by each mechanism, and even if one full node fails, the operation of the whole block chain network cannot be influenced. The electronic license data written into the electronic license database can be stored in a structured data format, so that the requirement data can be efficiently inquired by workers of each organization by using an electronic license management service system, for example, the requirement data is locally inquired based on SQL (structured query language) and other database inquiry languages, or the requirement data is searched by a search acceleration system arranged in the whole node locally, and the search acceleration system can be realized by using any technology supporting structured data search in the prior art.

In this embodiment, in order to facilitate a user to query an audit process of an electronic license, an electronic license block chain is implemented by using a multi-chain architecture, for example, as shown in fig. 6, the electronic license block chain is divided into an internal block chain and a public block chain, for the internal block chain, intra-organization intranet communication is used, so that related data of processes such as application, audit results, certificate handling and the like of the electronic license can be recorded, and a superior organization can track a current handling condition of a specified electronic license on the internal block chain; for the public block chain, internet communication is adopted, and access service is provided for users with query requirements, so that the users can conveniently query relevant data of the electronic license.

As shown in fig. 2, in order to ensure identity validity and authority control of the blockchain link points and blockchain accounts, an authorization and authentication platform or CA platform is introduced to provide identity authorization and authentication services for certificate authorities and masses. Aiming at a certificate handling organization, a worker of the certificate handling organization can send an authorization request to an authorization and authentication platform to request identity authentication and grant authority in the process of registering a login account of an electronic certificate issuing service system or an electronic certificate management service system; similarly, the masses can also send authorization requests to the authorization authentication platform when registering login accounts of related applications of the electronic license audit process query class. And after the authorization authentication platform performs authorization authentication on each login account, an asymmetric key pair is distributed to each login account, and an authorization authentication certificate, an authorization private key and other authorization authentication information are returned together. For example, an authorization certificate and an authorization private key may be stored in the flash disk, wherein the authorization certificate is digitally signed with the authorization private key. The authorized public key can be published by the authorization and authentication platform, and an authorized person can also obtain the public key through private key derivation. Moreover, for the certificate authority, the account authorized by the certificate authority can be operated by one person or any person on the same working post. The authorization authentication platform may perform uplink storage or not perform uplink storage on the authorization authentication information of each login account, such as the authorization certificate and the authorization public key. The blockchain account opened in the blockchain can also be applied for obtaining the authentication authorization of the authorization authentication platform.

For the blockchain node, the authentication authorization of the authorization authentication platform can be requested, so that the node capability of processing any transaction request related to the electronic certificate is provided. For example, for a household electronic certificate, an electronic device of an associated organization of a public security organization may apply for an authentication authorization to process such electronic certificate. On an unauthorized node, even if a transacting operation is performed, it is considered to have no authority.

Example one

Fig. 3 is a flowchart of an electronic license processing method disclosed in an embodiment of the present application, which may be applied to a relevant business scene of an electronic license, where an audit process of the electronic license is disclosed to a user based on a block chain, so that the user may query an audit progress situation anytime and anywhere, where the audit process includes various links involved in a process of handling a new electronic license and various links involved in a process of updating relevant information of an existing electronic license.

The method disclosed in this embodiment may be executed by a node where data of an internal block chain and a public block chain are deployed, and specifically may be executed by an electronic license processing apparatus configured in the block chain node, where the apparatus may be implemented in a software and/or hardware manner, and the block link point may be implemented by any electronic device capable of implementing the electronic license processing method, such as a server, a mobile terminal, a personal computer, and the like.

S101, an electronic license processing transaction request initiated based on an internal block chain is obtained.

The electronic certificate processing transaction request can be a transaction request generated by an internal block chain of the electronic certificate at any time node in an auditing process of newly processing or updating the existing electronic certificate. Taking the data of the certificate handling user needing to be uploaded in the process of handling the electronic certificate as an example, an organization worker can log in the system by using a login account of the electronic certificate issuing service system of the organization worker and input the information provided by the certificate handling user, the local node sends the received user information to the internal block chain, and the internal block chain initiates a data uploading transaction request according to the user information.

Optionally, the electronic license content in the electronic license processing transaction request is generated based on a preset license content template deployed in the internal blockchain system. The preset license content template, as shown in fig. 4, is a normative template with universality, which is pre-deployed in the internal blockchain system, and may be implemented in the form of a template intelligent contract or in the form of a data table, which is not specifically limited in this embodiment. The information fields in the template may include, but are not limited to, standard attribute fields, management information fields, business data fields, collateral file fields, and tag name fields, among others. The management information field comprises a life cycle record field and an identification code field, and the identification code field is used for storing an identification code for uniquely identifying the electronic license; the standard attribute field is used for storing basic information of the electronic certificate, such as a certificate number, a certificate name, a type, holder information, an issuing authority and the like; the digital signature stored in the digital signature field can be used for verifying the validity of the electronic certificate, and the digital signature can be generated based on a private key in a certificate handling organization; the business data field can be a field corresponding to any data supporting query in the electronic license data and is related to a specific electronic license business type; the attached file field may be used to store any type of file associated with the electronic license, such as a document, image, or scanned piece, to increase the integrity of the electronic license data.

Optionally, the obtaining of the electronic license processing transaction request initiated based on the internal block chain may include: displaying a license content acquisition interface through a certificate issuing service system according to an information field of a preset license content template deployed in a block chain system inside the electronic license; receiving license information and license handling instructions submitted through a license content acquisition interface; and according to the license handling instruction, the license information corresponds to each information field and is sent to the internal block chain, so that the internal block chain generates an electronic license handling transaction request. Specifically, after the certificate issuing service system is started, a worker logs in the system by using the system login account, after the login is successful, the node equipment displays the certificate content acquisition interface, and the worker inputs the information of the user into an information frame displayed on the current interface according to the type of the electronic certificate to be transacted. After the license information is input through the license content acquisition interface, a worker can trigger a license handling instruction by clicking the license handling control on the interface, and the license handling instruction can be used for instructing handling of a new electronic license and can also be used for instructing updating of different handling operations such as an existing electronic license.

In the generation process of the electronic license processing transaction request, all information fields or part of information fields in the preset license content template can be used according to the field use limiting conditions to generate the electronic license content. The specific content of the field use limiting condition can be adaptively set according to the type of the electronic certificate and the operation type related to the electronic certificate processing transaction request. Moreover, the certificate issuing service system shows the certificate content acquisition interface, and can show different page contents according to the use requirements of different information fields in a preset certificate content template, so that different certificate information filling templates can be provided for different electronic certificate types. The preset license content template is deployed, so that electronic license content can be stored in a standardized and unified manner, centralized management is realized, and phenomena of data loss, inconvenience in query and the like caused by non-standardized content and scattered storage of the electronic license content are avoided.

S102, executing the electronic license processing transaction request to generate electronic license processing transaction data, and adding the electronic license processing transaction data into the internal block chain.

And if the local node is a full node, directly executing the electronic certificate processing transaction request, and if the local node is a lightweight node, transmitting the electronic certificate processing transaction request to the internal block chain network to request the full node to execute. Before the whole node executes the electronic license processing transaction request sent by the lightweight node, the verification of the electronic license processing transaction request can be realized by verifying authority information carried in the electronic license processing transaction request, and the authority information can be used for representing the legality and validity of the electronic license processing transaction request. And if the full node verifies the authority information, the verification of the electronic license processing transaction request is passed. The authority information is optionally the digital signature information in the preset license content template, and certainly, the authority information is not limited thereto.

By chaining and storing the generated electronic license processing transaction data, the problems that supervision of electronic license data is weak, cross-mechanism inquiry of the electronic license data is difficult and the like due to independent processing of electronic licenses by each mechanism in the prior art can be solved, effective supervision of the electronic license data is realized, and the storage and interaction of the electronic license data are more convenient and reliable; moreover, the phenomena that electronic license data of each organization are stored by using a centralized electronic license database in a traditional business scene, large-scale electronic license service is unavailable due to database collapse, and the database is damaged irreversibly due to illegal attack are avoided.

Optionally, processing operation information corresponding to the electronic license processing transaction request is added to a life cycle record field in a preset license content template deployed in the internal block chain system. Through carrying out electron license processing affair request, the processing operation information that this processing affair request corresponds also links the chain storage in the lump, and along with processing operation's production, the life cycle information of electron license is constantly updated, has guaranteed the traceability of the processing operation information of electron license, has improved the standardization of electron license processing procedure, and then has realized the effective supervision to electron license business to and make electron license processing procedure standardized. For example, after a data upload transaction request is generated in the process of handling the certificate in the above example, by executing the data upload transaction request, the preset certificate content template not only stores the entered user information, but also stores currently executed operation information, namely data upload, so as to indicate that the current life cycle information of the electronic certificate is in a data upload state.

S103, if the electronic license processing transaction data are determined to have the public attribute, generating a cross-chain storage transaction request of the public data based on the deployment data of the public block chain.

The disclosure attribute is used to represent a data object in the electronic license processing transaction data that may be disclosed to the public. The data object with the disclosure attribute may be a default setting in the internal blockchain, or may be a setting selected by a worker in the business system interface, for example, the worker determines that the data can be disclosed by clicking a button or control such as "pass", "confirm" in the business system interface. The data objects with public attributes may be different depending on the type of electronic license.

In the process of determining whether the electronic license processing transaction data has the public attribute, monitoring the generated electronic license processing transaction data by the internal block link point, and if the data with the public attribute, namely the public data, is monitored, sending the public data to the public block chain; or monitoring electronic license processing transaction data generated in the internal block chain by the public block chain link point, and acquiring if the public data is monitored, so that a cross-chain storage transaction request of the public data is generated based on the deployment data of the public block chain, namely the public data is requested to be stored to the public block chain from the internal block chain. Data that does not have public properties is still stored in the internal blockchain. Because some block chain nodes are simultaneously deployed with the rule data and the block data of the electronic certificate internal block chain system and the public block chain system, the data of the internal block chain and the public chain can be simultaneously read, and a transaction request is initiated based on the rules of different block chains, so that the chain crossing operation is completed. The rule data of the blockchain system include, for example: P2P network communication protocol, consensus mechanism, incentive mechanism, intelligent contract, etc. to support the operation of the blockchain system.

Optionally, generating a cross-chain storage transaction request of the public data based on the deployment data of the public blockchain includes: and generating a cross-chain storage transaction request of the public data based on the deployment data of the public block chain, performing digital signature on the cross-chain storage transaction request by using an initiating account private key, and carrying the digital signature and an authorization certificate sent by an authorization authentication platform on the cross-chain storage transaction request of the public data.

The initiating account may refer to a login account of an electronic license issuing service system or an electronic license management service system authorized by the authorization and authentication platform. For each organization, an asymmetric key pair inside the organization can be distributed to each system login account, and staff of each organization logs in an electronic license certification business system or an electronic license management business system by using the login account authorized by an authorization and authentication platform, and can perform digital signature by using an account private key distributed inside the organization in the process of triggering a cross-chain storage transaction request to represent that the cross-chain storage transaction request is initiated by the organization. The digital signature and the authorization certificate are carried in the cross-chain storage transaction request and can be used for verifying the validity of the cross-chain storage transaction request by other nodes.

And S104, sending a cross-chain storage transaction request to the public blockchain based on the deployment data of the public blockchain so as to store the public data in the public blockchain.

The public block chain node receives and executes the cross-chain storage transaction request, and realizes that the public data is stored in the public block chain, namely, the transparency of the electronic certificate auditing process to any user with the query requirement is realized, so that the user can query the data by accessing the public block chain.

Optionally, sending the cross-chain storage transaction request to the public blockchain may include: and sending a cross-chain storage transaction request to the public block chain in real time or periodically through a preset node or a central service platform in the internal block chain. Regarding the preset node or the central service platform, on the basis of ensuring the identity to be reliable, the embodiment is not particularly limited, the preset node may be any trusted node in the internal block chain, and the central service platform may be any trusted third-party service platform.

The cross-chain storage transaction request may be sent in real time or periodically, and may be specifically set according to different service types, and preferably, the cross-chain storage transaction request is sent to the public block chain while uplink storage is performed in the internal block chain. Moreover, the cross-chain storage transaction request may include block identification information corresponding to the current public data in the internal block chain and processing operation information corresponding to the executed electronic license processing transaction request, where the block identification information may be a block ID, the processing operation information may be operation identification information, and the like, and both the block identification information and the operation identification information have uniqueness.

According to the technical scheme of the embodiment, the electronic license processing transaction data with the public attribute in the internal block chain is transferred to the public block chain through a double-chain architecture based on the internal block chain and the public block chain, so that the transparency of the public data in the electronic license auditing process to any user with an inquiring requirement is realized, the user can inquire the electronic license auditing process more conveniently, particularly for mass users, the inquiry of the electronic license auditing process can be carried out anytime and anywhere by accessing the public block chain, and the problem of inconvenient inquiry caused by the fact that the existing electronic license auditing process only supports field inquiry is solved.
