Detailed Description

The present application will be described in further detail with reference to the following drawings and examples.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the description of the present application is for the purpose of describing particular embodiments only and is not intended to be limiting of the application.

The embodiment of the application provides a data sharing method based on a service, which can be applied to a data interaction platform, and before introducing the method, the data interaction platform related to the embodiment of the application is simply introduced as follows:

as shown in fig. 1, the data interaction platform may include: a database 101, a blockchain network 103, and a management server 105.

The database 101 may store raw data (also referred to as source data) for various departments (also referred to as domains) of various industries. For example, to avoid data leakage and enhance data security, raw data of various departments in various industries may be stored in an internal local area network (i.e., intranet), i.e., source data is not visible to the intranet. For example, database 101 may include: based on industry and/or department partitioned DBs (databases), source data between DBs cannot be directly associated and accessed.

The blockchain network 103 is used to store the full directory index (i.e., the collection of directory information) for each domain of each industry. The blockchain network 103 is a decentralized, shared data storage network based on a distributed network, and may include a plurality of blockchain nodes for storing shared data based on a consensus mechanism. Illustratively, the data stored by blockchain network 103 includes two parts, the first part being a catalog blockchain 1031 generated based on the catalog index for the industry and department; the second part is a service block chain set 1032 corresponding to service block chains of different services, which is formed by arranging and combining different directory indexes according to service needs.

The management server 105 is configured to construct an intelligent contract set of each service based on the service block chain of the different services. For example, an intelligent contract set includes: service 1 intelligent contracts, service 2 intelligent contracts, … … service m intelligent contracts, … … service n intelligent contracts. Wherein m is a natural number greater than 2, and n is a natural number greater than m. It will be appreciated that each service intelligence contract corresponds to a respective service blockchain, and the service intelligence contract may be a set of digitally defined commitments (commitments) for agreement of a contract participant to perform a commitment on a service blockchain.

For example, a catalog index (i.e., a collection of catalog information) for each DB may be constructed based on a data transfer room, and the data transfer room links the catalog index for each department of each industry to the catalog blockchain 1031, and the raw data for different departments of different industries corresponds to the constructed catalog index for the department of the industry, for example, the raw data for the 1 st department DB of industry corresponds to the 1 st department catalog index of industry. Then, different directory indexes are arranged and combined according to service needs to form service block chains of corresponding different services. Based on the above, an intelligent contract set of each service is constructed. Thus, based on the data interaction platform, the corresponding big data application business service based on the block chain and the data transmission room can be executed. The big data application service here may include, but is not limited to, government affairs inquiry, civil data inquiry, directional recommendation, personal data linkage inquiry, associated application, etc. according to application types. According to the business field, the services can include but are not limited to government affairs services, public services, medical services, tax services, transportation services, poverty relief recruiters and the like. The division of the industry and the department can be performed based on a classification rule related to the big data, which is not specifically limited in the embodiment of the present application.

As shown in fig. 2, a method for sharing data based on a service in an embodiment of the present application includes:

step 201, receiving a service request sent by a request terminal;

here, the requesting terminal may be a client corresponding to the requesting user, where the client includes, but is not limited to, a mobile phone, a notebook, a tablet computer, a desktop computer, and the like. The requesting terminal may send a service request to the management server 105, where the service request may include a service identifier for identifying a service type, and may also include a service operation parameter corresponding to a corresponding service type, for example, the service operation parameter may be a parameter related to service query or a parameter related to service management, and a person skilled in the art may perform reasonable design according to a service requirement, which is not limited herein.

Step 202, reading a target service block chain corresponding to the service request stored in a service block chain set based on the service request;

for example, before reading a target service block chain corresponding to a service request stored in a service block chain set based on the service request, a service intelligence contract of the service request may also be determined based on the service request.

Illustratively, the management server 105 may read a service intelligence contract for a service request based on a service identification in the service request. In practical application, the management server 105 further stores a corresponding relationship between the service intelligent contract and the service identifier, and the service intelligent contract of the service request can be determined based on the corresponding relationship and the service identifier carried by the service request.

Illustratively, each service intelligence contract corresponds to a corresponding service blockchain, and the management server 105 may read the corresponding service blockchain (i.e., the target service blockchain) based on the service intelligence contract.

Step 203, determining the catalog information of the cross-department source data to be accessed by the service request based on the target service block chain;

illustratively, the target service block chain stores directory information of source data of different departments corresponding to the service request. The specific directory information may be preset based on a business intelligence contract. For example, the business 1 blockchain is generated based on the combination of the business 1 department 1 directory index, the business 1 department 2 directory index and the business 2 department n directory index, that is, the business request corresponding to the business type needs to use the original data of the business 1 department 1, the business 1 department 2 and the business 2 department n.

Step 204, obtaining an access address of the source data based on the directory information;

here, the mapping relationship between the directory information and the access address of the source data of each department is constructed based on the data transfer room and stored in a directory block chain, and each service block chain in the service block chain set is generated based on the combination of the directory information of at least two departments in the directory block chain. Here, the at least two departments may be departments of the same industry, or may include at least one department of a different industry, that is, the source data corresponding to the service request may be source data of cross-departments within the same industry, or may be source data of cross-departments.

Illustratively, the obtaining the access address of the source data based on the directory information includes:

It can be understood that the mapping relationship between the directory information of the source data stored in the directory block chain and the access address may be determined based on the directory block chain and the directory information of the source data to be accessed by the service request.

Step 205, accessing the source data based on the access address, and responding to the service request;

illustratively, the management server 105 may access the source data based on the access address and respond to the service request. For example, if the service request is a query request, returning a query result to the data request end; and if the service request is a processing request, performing service management, change, deletion, addition and other processing based on corresponding source data, and feeding back a processing result to the data request end.

The data sharing method based on the business can respond to source data of different industries and/or different departments based on the business request, and as the directory block chain and the business block chain set do not relate to specific source data, centralized sharing of the data is not needed, so that the safety protection difficulty, the exposure surface and the risk of data leakage are effectively reduced, and the privacy of data of all parties is ensured; the safety and credibility of cross-industry and cross-field multi-department data exchange and business collaboration are enhanced, the data of each party is guaranteed to be non-falsifiable, controllable and safe, meanwhile, the transparency and traceability of the business process are guaranteed, and the promotion of the safe application of the big data is facilitated.

In some embodiments, before determining the directory information of the source data to be accessed by the service request based on the target service block chain, the method may further include:

For example, before performing step 203, the access right of the requesting terminal may be authenticated based on the service intelligence contract, and if the authentication is passed, the service request is indicated as being authentic, and the subsequent steps 203 to 206 are continued. If the authentication is not passed, the service request is not credible, and the subsequent operation of the service request is terminated. Therefore, the security of the service request of the big data can be enhanced, and the service access and/or service management of an unauthorized user can be avoided.

For example, the authentication of the access right of the requesting terminal based on the service intelligent contract may be verification of the identity of the requesting terminal based on the service intelligent contract, for example, the management server 105 sends relevant information such as the login identity of the requesting terminal to the service intelligent contract for access right authentication, if the authentication is passed, the subsequent steps 203 to 206 are continuously performed, and if the authentication is not passed, the access of the service request is terminated. The service block chain can also record the access authority authentication result, so that subsequent tracing management is facilitated.

In some embodiments, before determining the access address of the source data based on the directory information and the mapping relationship stored in the directory block chain, the method further includes:

a data conveyance room determines catalog information for the source data based on metadata for the source data;

For example, the data transfer room may collect metadata of source data in the DB of each department of the industry, for example, an access address of the source data, and translate the source data into simplified directory information based on the access address. Namely, the directory information of the source data is obtained by translation and simplification based on the access address of the source data. It should be noted that the metadata may also be other data used for describing the source data, for example, a file name used for uniquely identifying the source data, and the like, that is, the directory information of the source data may also be obtained by translating and simplifying based on the file name of the source data. Here, the directory information is used to simplify metadata of the source data and implicitly express the source data, thereby reducing the data amount of the directory block chain and satisfying the confidentiality requirement of the source data.

In some embodiments, before accessing the source data based on the access address, the method further comprises:

For example, the data delivery room may further authenticate an access right of a requesting terminal before accessing source data of an intranet based on an access address, map directory information to the access address after determining that the requesting terminal has the access right of the directory information of the source data in the directory block chain, and access the source data based on the access address.

In some embodiments, the data sharing method further comprises:

and recording an access record of the directory information of the source data accessed by the request terminal in the directory block chain.

For example, the data transfer room may record an access record of directory information for requesting a terminal to access source data on the directory block chain based on an intelligent contract of the directory block chain, thereby facilitating subsequent tracing of access to the source data of departments of various industries based on the directory block chain.

In some embodiments, the data sharing method further comprises:

Illustratively, the management server 105 can record a processing record of a processing result of a response service request on a target service block chain based on a service intelligent contract, so that the safety and credibility of cross-industry and cross-domain multi-department data exchange and service collaboration are enhanced, the non-falsification, controllability and safety of data of each party are ensured, meanwhile, the transparency and traceability of a service process can be ensured, and the promotion of large data security application is facilitated.

In an application example, catalog indices (i.e., collections of catalog information) for each DB may be built based on a data relay room, and the data relay room links the catalog indices for each department of the industry to the catalog blockchain 1031. The data communication room may enable secure data interaction between the database 101 and the blockchain network 103. Illustratively, the data communication room may include: the system comprises an access control module and a data ferry center module.

And the access control module is used for performing identity authentication and access control on a user accessing the source data of the intranet. And judging whether the identity authentication is carried out, namely whether the user name and the password are matched or not, simultaneously verifying whether the input verification code is matched with the verification code randomly generated at the moment, and if the verification code is matched with the verification code, judging the identity authentication as a legal user, otherwise, judging the identity authentication as an illegal user. For access control, the access control module performs internal and external network conversion, and converts the access control on the source data of the internal network into the access control on the directory information presented by the service system in the data ferry center. The specific implementation process is as follows: and displaying the real service system name of the internal network to a user as a directory entry in directory information, wherein the content only builds a presented page in a text form and does not have an instruction operation function. If the access control judges that the operation authority exists, displaying the address information of the original data through a directory mapping relation; if the access control is determined to have no operation authority, the address information of the original data is not displayed. And judging whether the user is allowed to carry out the data ferry center module or not and which authorized part in the data ferry center module is entered according to the result of the access control. The access control judging process comprises the following steps: calling out the access control matrix of the user who passes the identity authentication, comparing authority values one by one, and if the authority values pass the item comparison, having the authority to access; if the authority value is compared with the failed item, no authority is given to access. The specific implementation is realized through an intelligent contract of the block chain.

The data ferry center module has multiple functions. One is to collect, submit and present the intranet and extranet data, and is the display function for the user to operate. The data acquisition is that the intranet provides the directory information of the intranet for acquisition. The submission of the data means that the user clicks or fills in the directory chain system to access the directory information and submits the directory information through a submission button. The presentation means that the directory information of the original data of the business system is displayed. And secondly, the function of carrying the data isolation and exchange of the internal network and the external network is carried out, a control unit is arranged between the external network and the internal network in an operation mode similar to a single-pole double-throw switch to realize data ferry, and an encryption and decryption unit and a digital signature unit of data are added in the control unit of the internal network to carry out confidentiality and anti-denial protection on the data of the external network. The encryption process is realized by carrying out encryption operation on input data through a traditional encryption algorithm to obtain a ciphertext and then transmitting the ciphertext. The decryption process is realized by carrying out decryption operation on the received data through a secret key so as to obtain an original plaintext. The digital signature process is realized by operating data through a private key to obtain signed information. The digital signature verification is realized by adopting a public key to calculate received information to obtain original information, thereby verifying the source of the information and preventing the information from being repudiated. Thirdly, mapping and conversion of intranet data, security audit, key and signature management, user data access control, user authentication and certification, intranet service system interface management and the like are realized. The mapping and conversion are carried out by carrying out directory mapping on the acquired directory information and the address information of the original data and then mapping the directory information and the address information of the original data. The safety audit is to log each operation and obtain the audit result through subsequent analysis. Key and signature management is a common application of modern cryptography. Access control, user authentication and authentication are achieved by a username, password, authentication code, and access control permission matrix. The interface management is realized by the universal system interface management.

The data ferry center module is formed by directory information and mapping relations in a directory block chain and various intelligent contracts during specific implementation. Firstly, the above information items are obtained. And secondly, mapping relation conversion is carried out on the directory information, so that an access address of the original data is obtained, and the access to the directory in the data ferry center is converted into the access of an intranet system.

Illustratively, as shown in fig. 3, the intranet 1 corresponds to the data transmission room 1, the intranet 2 corresponds to the data transmission room 2, … …, and the intranet n corresponds to the data transmission room n, that is, the DBs of the source data of each department are arranged in one-to-one correspondence with the data transmission rooms, so that the source data between the DBs cannot be directly associated and accessed, which is beneficial to enhancing the security of the source data. The n data conveyance rooms may constitute a directory blockchain as nodes on the directory blockchain.

It can be understood that the data sharing method based on the service in the embodiment of the present application can implement secure computation and big data application under the condition that the source data is not copyable. And based on the combination of the service block chain and the directory block chain, the safety and credibility of cross-industry and cross-field multi-department data exchange and service collaboration can be enhanced, and the data of each party can be guaranteed to be untrustable, controllable and safe. Based on the data record of the block chain, the transparency and traceability of the business process and the privacy of data of all parties can be ensured. Therefore, the method can promote the safety application of cross-industry and cross-field big data, and has wide popularization and application prospects.
