Detailed Description
Unstructured data has great value and is a gold mine to be developed, but due to the characteristics of low value density and complex structure of the unstructured data, the unstructured data is difficult to utilize. Referring to fig. 1, an embodiment of the present application provides a method for managing an unstructured document based on a blockchain technique, including:
step S11, identifying file generation and circulation attributes in the unstructured document;
step S12, establishing the association of a plurality of unstructured documents by using the file generation and circulation attribute relationship to form a file content database list;
step S13, data of the database list are classified and gathered;
step S14, establishing a structured database according to various data category attributes;
step S15, fusing and storing the unstructured document and the structured database;
and fusing and storing the unstructured document and the structured database to an unstructured data center.
The method and the device realize the structured management of the structured attributes and the incidence relation on the basis of the unstructured data.
And step S16, carrying out hierarchical authority management on the stored unstructured document and the structured database, and writing the authority control information into the blocks of the block chain.
The blocks of the block chain are shown in fig. 5. The authority management of the unstructured document is realized by utilizing the data center characteristic of block chain decentralization, the information non-tampering asymmetric encryption and authorization technology and the information trust mechanism.
A reliable database is maintained in a decentralized mode, blocks (Block) are related by a certification secret data module and a digital signature cryptography method, each data Block contains all data information of a system in a certain time, and the digital signature is generated to verify the validity of the information and is linked to the next data Block to form a main Chain (Chain). And the distributed storage of the computer is used for carrying out mathematical calculation for integration, so that the files of all parts are effectively associated and managed.
After the authority control information is written into the blocks of the block chain, when a user wants to verify the historical data, the verification can be completed by tracking the blocks to which the data belongs through a series of operations based on cryptography and data structure. In addition, the adjustment of the answer difficulty of the random number can control the generation speed of a new block; the generation of the block chain private key depends on the random number, whether the encrypted asset is safe or not is related to whether the random number can not be predicted or decrypted. The confidentiality of the private key can ensure and realize the safety of the authority management.
Fragmentation is severe based on unstructured data. The same document may have multiple copies in different data centers and different personal terminals, the document repeatability is serious, the uniqueness of the document cannot be verified, and the security of document information cannot be fundamentally solved because the unstructured document control generally adopts a read-only mode. The method comprises the steps of storing all data in the unstructured data center, enabling each piece of data to be accessible through a unique ID, constructing a block-based authority control table by using a block chain technology, and controlling the authority of accessing the unstructured data center and reading the data.
According to the method, a relational network among unstructured data is constructed, a systematic unstructured data map is formed, and unstructured data utilization is enhanced; the access control system based on the block chain solves the access authority control problem of the unstructured data to a certain extent, and fundamentally solves the problem of the safety of file information.

It is reported that only 1% -5% of the data on average are structured data. Today, this explosive growth of unused data consumes the storage capacity of complex and expensive primary storage in the enterprise. File circulation is also mostly realized by continuously generating copies, such as a mail system, and a large amount of storage space is occupied.
Based on the problem of large occupation of storage space, in the embodiment of the application, the converged storage includes storage in a distributed file;
the distributed files are disk spaces on each machine in the application cluster server used through a network, and the scattered storage resources form a virtual storage device.

The method and the device utilize the vacant disk space, and improve the utilization rate.
Further, the right control information includes read, write, modify, copy, and delete.

step S24, data of the database list are classified and gathered;
step S25, establishing a structured database according to various data category attributes;
step S26, fusing and storing the semi-structured document and the structured database;
and fusing and storing the semi-structured document and the structured database to the unstructured data center.
And step S27, carrying out hierarchical authority management on the semi-structured document and the structured database in storage, and writing the authority control information into the blocks of the block chain.
According to the method and the device, the unstructured data are subjected to semi-structured conversion, the attribute information of the unstructured data is improved, the relation network between the unstructured data is constructed, a systematic unstructured data map is formed, and the use of the unstructured data is strengthened.
Compared with common unstructured data, the semi-structured data has certain structurality, structured information in the semi-structured data can be extracted through unstructured data processing means such as semantic retrieval, keyword and abstract extraction and the like, and a relational map is constructed on the related structured information.
The semi-structured data has the characteristics of self-descriptiveness of a data structure, complexity of data structure description and dynamics of data structure description, and the semi-structured data is more complex and uncertain, so that the semi-structured data has higher flexibility and can meet wider application requirements.
The method and the system utilize the semi-structured database to realize storage and management of semi-structured data, construct an unstructured data center, and utilize unstructured documents, metadata and authority control documents to realize dynamic management of the unstructured documents.
