Embodiment Construction

[0045]In this embodiment, a database data storage and anti-tampering system based on a blockchain contract is applied to the scene where the database data is stored on the blockchain, and for the hidden dangers and practical problems of centralized management, in On the basis of the self-discipline of the centralized management party and the third-party credit endorsement, the distributed accounting technology of the blockchain is introduced to record the modification and downloading of the database by the centralized management party and its staff. Managed website users improve the transparency of database management, deter, prevent and even eliminate the centralized management and its staff from secretly "doing evil", and also provide the centralized management with a set of self-discipline management methods based on blockchain technology. Specifically, proceed as follows:

[0046] Step 1. After obtaining the structure of the table in the database and recording it as a tabl...

Abstract

The invention discloses a database data storage and tamper-proofing system and method based on a block chain contract, which are applied to a scene of storing data of a database in a block chain. The database data storage and tamper-proofing system comprises a block chain contract subsystem, a database data uplink subsystem and a data verification subsystem, wherein the block chain contract subsystem comprises a block chain contract module and a block chain contract interface module; the database data uplink subsystem comprises a database monitoring module and a block chain contract calling module; the data verification subsystem comprises a data query module and a data comparison module. According to the method, the database data can be safely stored in the block chain contract, all data and operation information of the database can be recorded, and the data on the block chain can be verified and compared with the database data to serve as an evidence for judging whether the database is tampered or not.

Description

technical field [0001] The invention relates to the field of blockchain-to-database data storage, in particular to a database data storage and tamper-proof system and method based on blockchain contracts. Background technique [0002] Today's global information Internet sites are developed on the information superhighway, and all adopt centralized management methods, that is, there are databases controlled by centralized managers. As ordinary users (including but not limited to publishers, Consumers, browsers), can create and disseminate text, pictures, sounds, videos and other information on the website controlled by the centralized management party, and can also be on the website controlled by the centralized management party (including the centralized management party as a third party) Credit endorsement) to trade, consume or obtain information, but there is a big "hidden danger": [0003] Purely from a technical point of view, the centralized management party or its dat...
