Referring to fig. 1, a cross-region sharing method for electronic license data provided by the present invention may include the following steps:
101. and acquiring a first electronic license file to be stored and first electronic license information.
In the embodiment of the invention, each block storage node subset can use the electronic license file and the electronic license information in the block, and then the storage process of the electronic license data in the embodiment of the invention is described by taking the storage process of the first electronic license file and the first electronic license information as an example. The electronic license file refers to electronic license data, and the electronic license data under different service scenes can be different. The electronic license information can be the face information of the electronic license, for example, the face information is the character information displayed on the license, and the electronic license information is the core information of the license, for example, who has what license, what unit issues, when overdue, whether valid or not, and the like. The data volume of the electronic license file in the embodiment of the invention is usually larger than that of the electronic license information.
In some embodiments of the present invention, the step 101 of obtaining a first electronic license file and first electronic license information to be stored includes:
acquiring first electronic license source data from an electronic license system;
converting the first electronic license source data into a first electronic license format file;

and generating a first electronic certificate file and first electronic certificate information according to the first electronic certificate layout file and the corresponding electronic signature, wherein the first electronic certificate file comprises the electronic signature and first electronic certificate data.
The data source end provides the electronic license by the electronic license system of the data providing area, the electronic license is stored on the initialized block chain node after the electronic license is generated, and then the electronic license is broadcasted to other nodes from the initialized node, and other nodes belong to other storage devices, and the description of the storage process of the electronic license in the subsequent embodiment is described in detail.
102. Writing a first electronic license file and first electronic license information into an account book corresponding to a first subset block chain of a first block storage node subset through a pre-configured electronic license service contract relation, and synchronously writing the first electronic license file and the first electronic license information into the account book corresponding to all subset block chains except the first subset block chain in the first block storage node subset, wherein the first block storage node subset comprises N subset block chains including the first subset block chain, and N is a positive integer greater than or equal to 2.
In the embodiment of the invention, the contract relation of the electronic certificate service is completed by pre-configuration, and the contract relation of the electronic certificate service represents the storage path and the storage relation of different electronic certificates and a full-set block chain in a cross-block storage node corresponding to a storage node in a block. In an embodiment of the present invention, the first subset of block storage nodes comprises a plurality of sub-set block chains, for example, N sub-set block chains from subset block chain 1 to subset block chain N. The first subset block chain is a subset block chain corresponding to the first electronic license file, for example, a storage node of a city level a corresponding to the first subset block chain, and a user corresponding to the first electronic license file belongs to the city level a, and at this time, the first electronic license file and the first electronic license information may be written into an account book corresponding to the first subset block chain of the first subset storage node subset. In order to ensure that the information is not tampered, after the first subset blockchain is stored, the first electronic certificate file and the first electronic certificate information are written into the account book corresponding to all the subset blockchains in the first block storage node subset except the first subset blockchain, so that the information is ensured to be not tampered, and the first electronic certificate file and the first electronic certificate information are stored in the first block storage node subset in a full amount, and the information is not easy to lose.
In some embodiments of the present invention, the step 102 writes, through a pre-configured electronic license service contract relationship, the first electronic license file and the first electronic license information into an account book corresponding to a first subset block chain of the first block storage node subset, and synchronously writes the first electronic license file and the first electronic license information into an account book corresponding to all subset block chains in the first block storage node subset except the first subset block chain, including:
inquiring a block storage node subset identifier and a subset block chain identifier corresponding to the first electronic certificate file according to the contract relation of the electronic certificate service;
determining a first block storage node subset from all the block storage node subsets according to the inquired block storage node subset identification;
determining a first subset block chain from all subset block chains of the first block storage node subset according to the inquired subset block chain identification;
writing the first electronic license file and the first electronic license information into an account book corresponding to a first subset block chain of the first block storage node subset;
and broadcasting the first electronic certificate file and the first electronic certificate information to the accounts corresponding to all the subset block chains in the first block storage node subset based on the synchronous accounting mode of the block chain accounts.
In some embodiments of the present invention, further, after synchronously writing the first electronic license file and the first electronic license information into the ledger corresponding to all subset blockchains except the first subset blockchain in the first subset of block storage nodes in step 102, the method for sharing electronic license data across regions further includes the following steps:
and generating a distributed trusted account book in the first block storage node subset according to the first electronic certificate file and the writing result of the first electronic certificate information in the first block storage node subset, and recording the first electronic certificate file and the first electronic certificate information through the distributed trusted account book.
For example, in the embodiment of the present invention, an electronic certificate file and certificate information are written into an account book in a provincial block chain of a local city through a block chain intelligent contract, and based on synchronous accounting of the block chain account book, the electronic certificate file and the certificate information are accounted on all local city block chain nodes in a province, so as to form a distributed trusted account book inside the local city, and record a newly added certificate file and certificate information. The intelligent contract of the block chain is a contract template which is suitable for different business definitions, for example, on the sharing of electronic certificates, the issuing unit civil bureau issues a marriage certificate to zhang san, and at this time, the intelligent contract content includes that the civil bureau issues the marriage certificate to zhang san, and the information of the marriage certificate is … …, and the identity of the civil bureau is used for authenticating the intelligent contract and is recorded on the account. Each province forms a block chain network, and after local city data is updated, the data of other block chain links in the province is updated in time. The new file is preferentially recorded on the block chain nodes in the local city, each intelligent contract has a unique Identifier (ID), the certificate confirms whether to be newly added or changed or not by calculating and comparing the certificate holder code, the certificate number and the issuing unit code, confirms the service state, and can be broadcast to other block chain nodes after the successful recording. According to the embodiment of the invention, the distributed trust account book in the block storage node subset can realize that information is not easy to lose and falsified, and meanwhile, the distributed trust account book is convenient to use to realize quick query and feedback of the electronic certificate.
103. And determining first routing information corresponding to the first electronic license file according to the contract relation of the electronic license service.
In the embodiment of the invention, the routing information corresponding to the electronic license file refers to the storage position of the block storage node subset in which the electronic license file is stored, corresponding to the whole set of the cross-block storage nodes, and the first routing information corresponding to the first electronic license file can be inquired according to the pre-configured contract relation of the electronic license service.
104. The method comprises the steps of writing first routing information and first electronic license information into accounts corresponding to a first full set block chain of a full set of cross-block storage nodes, synchronously writing the first routing information and the first electronic license information into accounts corresponding to all full set block chains except the first full set block chain in the full set of cross-block storage nodes, wherein the full set of cross-block storage nodes comprises M full set block chains including the first full set block chain, M is a positive integer greater than or equal to 2, and the first full set block chain corresponds to a first block storage node subset.
In the embodiment of the invention, the first electronic license file is not put in the block chain of the whole set of the cross-block storage nodes, and the file is too large to be put in the whole set of the cross-block storage nodes in consideration of the storage problem of the electronic license file per se, so that the routing information of each sub-set of the block storage nodes is added in the intelligent contract of the cross-block, for example, the routing information can be the IP address of each sub-set of the block storage nodes. The first routing information and the first electronic certificate information are written into an account book corresponding to a first full set block chain of a full set of cross-block storage nodes, and the first routing information and the first electronic certificate information are synchronously written into the account book corresponding to all full set block chains except the first full set block chain in the full set of cross-block storage nodes, so that the first electronic certificate information and the corresponding first routing information are synchronously stored in the full set of cross-block storage nodes, and the first routing information can be used for searching back a block storage node subset corresponding to the first electronic certificate information.
In some embodiments of the present invention, the step 104 of writing the first routing information and the first electronic certificate information into the account book corresponding to the first full set block chain of the full set of the cross-block storage nodes, and synchronously writing the first routing information and the first electronic certificate information into the account book corresponding to all full set block chains in the full set of the cross-block storage nodes except the first full set block chain includes:
searching a first full-set block chain corresponding to the first block storage node subset from the cross-block storage node full set according to the first block storage node subset;
writing the first routing information and the first electronic license information into an account book corresponding to a first full set block chain of a full set of cross-block storage nodes;
based on the synchronous accounting mode of the block chain account book, the first routing information and the first electronic certificate information are broadcasted to the account book corresponding to all the full-set block chains in the cross-block storage node full set.
In some embodiments of the present invention, further, after synchronously writing the first routing information and the first electronic license information into the ledger corresponding to all the full set block chains except the first full set block chain in the full set of cross-block storage nodes in step 104, the cross-region sharing method for electronic license data provided in the embodiment of the present invention further includes the following steps:
and generating a distributed trust account book in the cross-block storage node complete set according to the writing result of the first routing information and the first electronic certificate information in the cross-block storage node complete set, and recording the first routing information and the first electronic certificate information through the distributed trust account book.
For example, after the electronic certificate file and the electronic certificate information are written into the province-level block storage node, next, the routing information and the certificate information of the province are written into the national-level block chain account book of the province through an intelligent contract, the routing information and the certificate information of the electronic certificate are synchronously accounted on the basis of the block chain account book, the routing information and the certificate information of the province of the electronic certificate are accounted on all the national-level block chain link points, a national-level distributed trust account book is formed, and the newly added routing information and the certificate information are recorded. The intelligent contracts of province-level and country-level block chain nodes are different from the intelligent contracts in the province, and mainly comprise routing IP information of the province, license core information and license files which are not placed in a national block chain, and the files are too large and are not suitable for being placed in a national application in consideration of storage problems, so the routing IP of each province needs to be added in the national-level intelligent contracts, the country firstly inquires, returns routing information after inquiring the information, and a calling party accesses the detailed license information and the files according to the routing information. In the embodiment of the invention, the distributed trust account book in the block-crossing storage node complete set can realize that information is not easy to lose and falsified, and meanwhile, the distributed trust account book is convenient to use to realize quick query and feedback of the electronic certificate.
In some embodiments of the present invention, based on the foregoing implemented dual-layer storage mechanism of the electronic license information, a query scheme for the electronic license is described next, and the cross-region sharing method of the electronic license data provided in the embodiments of the present invention further includes the following steps:
receiving an electronic license data query request sent by a client through a first block storage node subset, wherein the electronic license data query request comprises: the electronic license data identification to be inquired;
inquiring whether electronic license information corresponding to the electronic license data to be inquired exists in the first block storage node subset;
if the requested electronic license information is inquired in the first block storage node subset, an electronic license file corresponding to the electronic license data identifier to be inquired is further acquired;
if the requested electronic license information is not inquired in the first block storage node subset, forwarding an electronic license data inquiry request to the whole cross-block storage node set;
inquiring whether electronic license information corresponding to the electronic license data to be inquired exists in the whole set of the cross-block storage nodes;
if the requested electronic license information is inquired in the whole set of the cross-block storage nodes, further acquiring routing information corresponding to the requested electronic license information;
and accessing the corresponding block storage node subset according to the routing information corresponding to the requested electronic license information, and acquiring an electronic license file corresponding to the electronic license data identifier to be inquired.
For example, the service system provides a certificate data query request according to service requirements, queries and acquires certificate information on a local city provincial block chain book, and solves the query and acquisition of intra-provincial data; meanwhile, license routing information is inquired and obtained on a state-level block chain account book of the province, and license information on other province-level block chain account books is accessed by a service system according to the routing information, so that cross-region license data inquiry and acquisition of other provinces are achieved.
In the embodiment of the invention, the license source data end converts the license data into the format file, and adds the electronic signature to provide the basic credible file and the license data, and the basic credible data is added into the block chain through the intelligent contract and is broadcasted to all the block chains to form the complete credible data of the whole network in one area. On the cross-region, a cross-region block network is established, routing information and license information of each region are added into a block chain and broadcast by taking the region (province) as a basic unit, and data in the cross-region block chain is completely credible. And finally, when the data is shared, accessing the block chains of other areas (provinces) according to the routing information on the basis of the routing information of the cross-area to acquire the cross-area credible data.
Fig. 2 is a schematic diagram illustrating an implementation principle of a blockchain of a provincial-level block storage node and a national-level block storage node according to an embodiment of the present invention. The block chains in the embodiment of the present invention can be divided into two types: the subset block chains and the full set block chains, such as the subset block chains, are mainly stored in a block storage node subset, such as the first provincial block storage node in fig. 2 is a first block storage node subset, the second provincial block storage node may be specifically a second block storage node subset, each block storage node subset includes a plurality of subset block chains, such as a city a, a city B …, and a city N, respectively, each block chain includes a plurality of blocks, such as block 1, block 2, …, and block N. For example, the corpus block chain is mainly stored in a corpus of trans-block storage nodes, for example, the country-level block storage node in fig. 2 is a corpus of trans-block storage nodes, a plurality of corpus block chains are included in the country-level block storage node, for example, for each province, a province a, a province B, …, and a province N, respectively, a block chain is provided, and a plurality of blocks, for example, a block 1, a block 2, a block …, and a block N, are included in each block chain.
The following description is given for the scenario shown in fig. 2, in which a block chain network is established by using a block chain technology, license data is converted into a layout file by a license source data end, an electronic signature is added to the layout file, a basic trusted file and license data are provided, the basic trusted data is added to the block chain through an intelligent contract and broadcast to all block chains, and data of a whole network in a region is completely trusted. On the cross-region, a block network of the cross-region is established, for example, based on the region (province) as a basic unit, the routing information and the license information of each region are added into a block chain and broadcasted, and the data in the cross-region block chain is completely credible. And finally, when the data is shared, accessing the block chains of other areas (provinces) according to the routing information on the basis of the routing information of the cross-area to acquire the cross-area credible data.
The embodiment of the invention generally utilizes a block chain technology to establish a block chain network, and realizes the collection and management, cross-area routing and sharing of electronic license information by means of decentralization, synchronous accounting, transaction identity authentication, data non-tampering, electronic signature and the like. The transaction identity authentication is implemented by using a digital certificate to ensure that the identity of each blockchain node is trusted, and other ways, such as oauth2.0 and the like. The embodiment of the invention can realize that information is not easy to lose, and the distributed account book based on the block chain technology disperses data on all nodes in a networking, and each node has full data, thereby avoiding the problems of unavailable networking and data loss caused by single point failure. The embodiment of the invention can also realize that the information cannot be tampered, once the information is verified by the intelligent contract and added to the block chain, the information can be stored permanently, and the modification of the database on a single node is invalid unless the plurality of nodes in the system can be controlled simultaneously. For example, when data is verified, the blockchain is verified in more than one block, for example, whether marriage certificate information of zhang san is correct is verified through a client application, at this time, broadcast is performed in the provincial node, the provincial node selects 1/3 (the value can be flexibly set) nodes for verification, if the verification is passed, the result is trusted, information tampering of all blockchains needs to control a plurality of nodes at the same time, the information can be guaranteed to be modified after being mutually trusted, and the modified single node cannot be written into the account book through verification. The embodiment of the invention also has great expansibility, and after the block chain sharing network is formed, scenes on the block chain network can be continuously expanded by dynamically issuing the intelligent contract. The mode of accounting in the embodiment of the invention has timeliness, and data can be synchronized to each node in the networking in time through synchronous accounting. In the embodiment of the invention, the data storage authority is clear, the cross-regional data is acquired, the data provider is responsible for service, the provincial level is taken as a unit, different provinces provide the sharing service of the data in the province, and each province only needs to collect necessary routing and license information to the national level block chain node.
