Detailed Description
The present invention will be described in further detail with reference to test examples and specific embodiments. It should be understood that the scope of the above-described subject matter is not limited to the following examples, and any techniques implemented based on the disclosure of the present invention are within the scope of the present invention.
Example 1
An architecture diagram of a big data management application system based on a chain number cube is shown in fig. 1, and includes a plurality of chain number cubes, each chain number cube establishes a bridge connection with a local database, a user imports local original data into the chain number cube in an ETL synchronization mode, encrypts and stores the imported chain number cube, and in addition, uplink of data ETL process information is also realized, and data interaction is performed between the chain number cubes through data messages. Each chain number cube includes functional modules such as a data directory, a search module, a data box, an intelligent contract, an ETL execution engine, a data lens, a chaining engine, and a block chain edge cloud node, and a functional architecture diagram of the chain number cube for data chaining is shown in fig. 2.
The overall architecture of the system takes a BD-WAN (block defined network) and a chain number cube as bottom-layer physical network support, integrates chain number search (data sharing), chain number intelligence (data visual detection), WBaaS (block chain service platform), and software products of an operation management background (basic data and system management), and all data are circulated and exchanged based on a trusted data environment. The system adopts a springclosed-based cloud native micro-service architecture as a technical architecture, and a schematic diagram of the technical architecture is shown in fig. 3. The server of the system comprises a portal, a chain number search, an execution engine, an uplink engine, a chain number intelligence, an operation background and vbaas. The server is linked with the service database and used for accessing mysql data and the elasticsearch data in the service database, and the server reads data in the data safety cabinet through the data lens; in addition, the servers are linked with the peer node, the orderer node and the ca node through special gateways. Accordingly, the physical architecture of the system is shown in fig. 4 and 5.
The system adopts a distributed structure to carry out networking, has easy expandability, can transversely expand an execution engine and a network, and adopts a BD-WAN block chain to define the network.
An important component of the system architecture is the chain number cube. The user can link the local original data into the cabinet through the chain number cube and perform data circulation with other chain number cubes. The uplink is ETL process information, and the entering into the cabinet means that original data is stored into a data encryption box of a chain number cube after being encrypted. After the hardware network is connected to the system, original data is not directly uplink, uplink is ETL process data of the original data, ETL process information is stored in a distributed account book of the block chain, and the original data is stored in a local data cipher box after being encrypted.
Each chain number cube includes a data directory, a search module, a data lockbox, a smart contract, an ETL execution engine, a data lens, a chaining engine, and a blockchain edge cloud node.
The data directory stores fields of accessible data of the chain number cube, and a user can select to display all the fields corresponding to the data in the local data cipher box in the data directory by setting, or not display all the fields, or display part of the fields in the data directory. The information stored in the data directory is used as data share and can be accessed by the chain number cube in other systems. One established screenshot of the data directory is shown in fig. 6. The list comprises a self-defined data set name, a chain number cube where the data are located, a data close box where the data set is located, a state, the number of applied times, the issuing time and the operation. Wherein the administrator may set the data set as retrievable or not retrievable, and when selected as retrievable, other chain number cube users in the network may search the data set through a search function. The applied times refer to the times that the data set is applied for access or export by other chain number cubes.
The search module is used for accessing data directories of other chain number cubes in the system. Before all data in the chain number cube are shared and exchanged, a user can perform high-level retrieval on the data in a simple and easy-to-use search engine mode through a search module, and a data directory is accessed to realize data awareness. A user needs to search target data in an engine first and then exchange and apply for the data; the traditional data directory index is replaced by a quick search mode, so that the data can be more conveniently known, and a typical search module interface is shown in FIG. 7. Through keyword search, a list of data sets in the network matching the keywords can be found, and the name of the chain number cube (data provider) where each data set in the list is located, the update date, the data description, the charging standard and the content of the data can be seen.
The data cipher box is used for encrypting the data and storing the encrypted data. The encryption adopts end-to-end constant encryption AE and TDE transparent encryption. The end-to-end constant encryption is an asymmetric encryption technology, and the transparent encryption is a symmetric encryption technology. In the local chain number cube, a plurality of data close boxes can be arranged according to requirements, and data in a data set can come from different data close boxes of the same chain number cube.
The intelligent contract is used for the data provider and the data buyer to reach an agreement and realize the data transaction. In the field of blockchain technology, smart contracts refer to computer programs that are triggered, non-tamperproof, and automatically executed based on a subscription event. During the data transaction process, based on the trusted and non-tampered data transaction information, an automatically executable program (smart contract) can be deployed on the blockchain, and the coverage range of the automatically executable program comprises a programming language, a compiler, a virtual machine, time, a fault tolerance mechanism and the like. The data asset supplier issues the data asset in the data asset trading platform based on the block chain to create an intelligent contract; triggering an intelligent contract through a buyer, and purchasing and paying to complete a transaction; and in the data asset transaction process, the uplink of data asset information, the uplink of data asset transaction users, the uplink of data asset transaction information and distributed storage are synchronously performed to each endpoint function in real time. In the technical scheme of the invention, the data transmission in the system is managed on the basis of the operation mechanism of the intelligent contract.
A typical transaction flow diagram for a smart contract is shown in fig. 8. The blockchain data asset transaction flow diagram illustrates:
1) the 'data asset supplier' issues 'data assets', firstly, the 'data assets' is registered, an intelligent contract is created, a 'data auditor' is waited for auditing, and the intelligent contract is put on shelf and written into a block chain after passing;
2) the data asset purchasing party purchases data assets, browses a data asset catalogue, selects required data, creates an order, triggers an intelligent contract, completes payment and writes transaction information into a block chain;
3) the intelligent contract comprises a data asset use role, time, times, fields and other limiting algorithms.
The ETL execution engine is used for extracting, converting and loading data. Importing external data into the chain number cube and exporting the data of the chain number cube are realized by adopting an ETL execution engine. Inputting data in the relational database, data in the nosql database, data on real-time stream, file stream and http into an ETL execution engine for ETL conversion, wherein the ETL conversion content comprises the following steps: data connection, data conversion, data desensitization, data encryption, data mapping, data statistics, data verification, data cleaning and the like. The working principle diagram of the ETL execution engine is shown in fig. 9. The data generated after the ETL conversion is completed is encrypted and stored in a data lockbox, and the whole ETL process information is loaded into the block chain through a data uplink engine entry message queue. The ETL process information includes a timestamp of the current operation, a source database name or a source data address, a source table name, a target database name or a target database address, a target table name, a hash value of the current operation data, the number of fields, the number of pieces, and the like, and the content of the ETL process information is shown in fig. 10, for example. When the ETL process information is uplinked, it is clear that the source and destination of the batch of data are recorded on the blockchain distributed ledger.
In particular, during data import and export, the ETL execution engine checks the data that performs the operation to ensure that the data has not been tampered before import and export.
The data lens is used for decrypting external access, and the data stored in the data encryption box can only be accessed through the data lens. Besides end-to-end asymmetric technology encryption, data in the data cipher box is also transparently encrypted by a symmetric technology, and a data user needs to preview or use the data in a limited environment, so that data leakage accidents are prevented. Meanwhile, data API sharing and library-level circulation are supported, and users can perform table association, table-level operation and the like in an encrypted database through authorization of a data lens. Because the data cipher box adopts end-to-end constant encryption AE plus TDE transparent encryption, the corresponding data lens decrypts the encrypted data through AE and TDE. Node key management based on TEE (trusted execution environment) and whole-course encrypted data transmission are adopted, the safety of data is guaranteed, and only a data owner or an approved data applicant calls a data lens through a unique key of the data owner or the approved data applicant, the data can be previewed and used, so that the data is safer and more secret; meanwhile, in the calling process of the data lens, a related fusing mechanism is arranged to prevent illegal calling and other behaviors of data.
The uplink engine is used for storing the ETL process information of the stored data or the ETL process information of the distributed data into the block chain account book.
The block chain edge cloud node stores a block chain account book, and the block chain account book is used for storing ETL process information of each chain number cube in the network.
Preferably, the user realizes data encryption, data storage and data uplink through the chain number cube. A schematic diagram of implementing data encryption, data storage, and data chaining by a chain number cube is shown in fig. 11, and the specific steps include:
a1, the ETL execution engine synchronously imports the original data into a data cipher box in an ETL mode, and in the importing process, the data cipher box encrypts the original data to obtain encrypted data and stores the encrypted data into the data cipher box;
a2, the uplink engine imports the original data into ETL process information of the data cipher box to perform uplink operation, and stores the generated block chain book into a block chain edge cloud node;
the ETL process information is in a one-to-one correspondence with the encrypted data, and the ETL process information includes, but is not limited to, the following: the operation comprises a timestamp, a source database name, a source table name, a target database name, a target table name and a hash value of the original data.
And the user realizes data access through the chain number cube, and the data access specifically comprises three modes of local access, data distribution and intelligent contract access.
The specific steps of local access include: and the local user directly decrypts the encrypted data in the data encryption box through the data lens in the own chain number cube and checks the decrypted original data.
The data distribution method specifically comprises the following steps:
c1, the user accesses the data directory of other chain number cubes in the system through the search module in the access end chain number cube, and obtains the data information and the target chain number cube where the data information is located from the data directory;
c2, establishing point-to-point link between the object chain number cube and the access terminal chain number cube through the handshake protocol of the data message;
c3, the access end chain number cube decrypts the encrypted data in the data encryption box through the data lens of the target chain number cube to obtain the data detail corresponding to the data information;
c4, the target chain number cube distributes the data detail corresponding to the data information to the access side chain number cube through the ETL execution engine, and the uplink engine performs uplink storage on the ETL process information of the data detail distribution.
The specific steps of intelligent contract access comprise:
b1, the user accesses the data directory of other chain number cubes in the system through the search module in the access end chain number cube, and acquires the data information and the target chain number cube where the data information is located from the data directory;
b2, after mutual verification is carried out on the intelligent contract in the access end chain number cube and the intelligent contract in the target chain number cube by the user, a point-to-point link is established;
b3, the access end chain number cube decrypts the encrypted data in the data cipher box through the data lens of the target chain number cube, and checks the data detail corresponding to the data information.
Another important component in the system is a data message, and data interaction is realized among chain number cubes through the data message.
The data distribution is performed through ETL operation, but a plurality of mature ETL tools such as ODI, Informatica, Datax, Kettle and the like exist in the market, different scripting languages used by different tools are different, codes are different, if only one tool can be used for analysis, the ETL tool cannot be fully utilized, but the workload is large when all scripts are analyzed. Therefore, a set of standard models is constructed, different types of ETL operation can be analyzed into a unified model, and networking transmission among chain number cubes is facilitated. Before data distribution, a handshake protocol carries out identity authentication of both sides, and both sides of data distribution are confirmed to be chain number cube main bodies. After the chain number cube is deployed, the chain number cube network has a unique number, whether the IP is in the chain number cube network or not is judged during identity verification, and communication connection is established after the verification is passed. Delta messages specify the contents of exchange data format, data type, expression mode and the like, and contain the specification of a communication model. The message consists of a message header and a message body, wherein the message header comprises some basic information, such as a message unique identification number, a reference message number, a resource version, a source node code, a target node code, basic operation, composite operation and the like. The Delta data message standard is shown in FIG. 12. The data message comprises a source node, a target node and an operation node; the source node is a node for accessing data, the target node is a node for accessing data, the operation node comprises basic operation and composite operation, and the basic operation comprises extraction, loading, filtering, conversion and duplication removal; compound operations include split, merge, join, associate, and custom. Fig. 13 shows an example of the application of the Delat datagram.

The safe comprises two types: a third-party cloud server cube and a chain number cube (all-in-one machine) type safe; and the user purchases the safe according to the actual requirements of the user. Enterprise users may assign purchased cube management rights to other members within the enterprise, enabling collaboration within the organization to operate more efficiently. For a user who purchases the third-party cloud server cube, the user can apply for the function of upgrading configuration on line, and after upgrading is completed, prompting is carried out in the cube state.

The system will automatically generate the corresponding ETL job according to the connection information input by the user. The system supports the way and frequency of synchronizing the data, and if the chosen way is periodic synchronization, the system will incrementally transfer the data into the cube. The cache record of the connection information of multiple databases is supported, and a user can enter the cabinet through the record without repeated operation. The granularity of the data synchronization function supports the table level, and the condition that the whole database is synchronized and occupies too many resources is avoided.
5. Data application management
As shown in fig. 17, the data application management interface exchanges data in an application manner after the data requesting party finds the target data, and the data requesting party can access the data after agreeing to apply the data. For the agreed application, there are two ways in which the system provides access: entering a cube of a data owner for data query through authorization; or directly transfer the owner's data to the applicant's cube in the manner of ETL. During the service handling process, the relevant users receive message prompts from the system. And supporting the inquiry of the details of the applicant and the application data set.
