Data management method, network, data acquisition and storage use method and system thereof

Abstract

A method for manage data The data management method comprises: for each platform center database, adopting block chain technology to establish corresponding block chain node, establishing block chainnetwork, any block chain node and all other block chain nodes can communicate bidirectionally and synchronize data by broadcasting; When the block link node saves the data, it encrypts the data step by step through Merkle tree, and saves the data to the block HASH. The latter block link node saves the HASH of the former block link node. The block chain technology is adopted to capitalize the data.When the data collection end uploads the data, the data collection end, the data source end and the data supervision end all obtain the income. When the data use end uses the data, it pays the fee tothe data collection end and the data source end. The data collecting end, the data using end, the data source end and the data supervising end are connected with the block link node through data routing.

Description

technical field [0001] The disclosure belongs to the technical field of data management, and relates to a data management method, a network and data collection and storage method and its system, and in particular to a blockchain-based data management method, network and data collection and storage method and its system . Background technique [0002] The statements in this section merely provide background information related to the present disclosure and do not necessarily constitute prior art. [0003] With the development of information technology and its application at various levels in different industries, factors restricting the development of informatization have gradually become prominent in the process of implementing various informatization needs. The same industry contains various departments, and each department has developed its own application system based on its own business needs. These systems are used for their own purposes, and it is difficult to effecti...

AI Technical Summary

Problems solved by technology

Although this method solves the problem of information islands, many problems gradually emerged during the use process

[0005] First, the centralized storage method of concentrating data on the public data platform cannot better guarantee the use of data, and is too dependent on the public data platform

With centralized storage, if the public data platform server of the storage center goes down or the network is interrupted, the collection, storage and use of data will be interrupted, the data will not be used normally, and the efficient use of data cannot be guaranteed;

[0006] Second, once the data is generated, it is objective and cannot be changed; however, due to the centralized data collection and storage management method, there is no data tamper-proof mechanism, and the data can be easily modified, so the objectivity and integrity of the data cannot be guaranteed. accuracy

[0007] Third, the collection, storage, and use of data are coordinated and managed by relevant management agencies, and tools for data collection, storage, and use are managed through administrative means. The data is not capitalized, and the enthusiasm and enthusiasm of medical institutions cannot be fully mobilized. Data rights and responsibilities It is also not clear that without data incentives, use, circulation and other mechanisms, it is impossible to effectively promote the use and value of data
