Database accessing authority control method and equipment based on block chain

Abstract

The embodiment of the invention provides a database accessing authority control method and equipment based on a block chain. The method comprises the steps that the block chain receives a database resource accessing request sent by a user terminal in a net node; the block chain looks up an accessing authority record at the net node according to identification information of the accessing authority record; if the accessing authority record comprises user identity information, identification information of a database resource which needs to be accessed and an accessing mode, the block chain sends the database resource accessing request to a database server at the net node, so that the user terminal obtains the database resource which needs to be accessed from the database server. The database server only stores the database resource and does not store the information about the database resource accessing authority of the user, the situation that the data resource accessing authority is possibly completely let out when the centralized storage method is damaged and falsified is avoided, the safety of the data resource in the database is improved, and the safety of the accessing authority of the user terminal is improved.

Description

technical field [0001] The embodiments of the present invention relate to the field of communication technologies, and in particular, to a blockchain-based database access authority control method and device. Background technique [0002] The database can be used to store various data resources. User terminals access data resources by accessing the database. Different user terminals can access different data resources. For example, some user terminals can access a certain table, and some user terminals can only access a few fields. [0003] The access rights of different user terminals to data resources are granted by the root super user, and the user terminal only obtains the access rights granted by the root super user, such as access rights to data tables, access rights to CRUD, or access rights to fields. The data resources in the database can only be accessed within the scope of the granted rights. In addition, the root superuser can also manage all data resources. ...

AI Technical Summary

Problems solved by technology

[0004] Once the user name and password of the root superuser are leaked, the access rights of data resources in the database may be completely leaked, and the rights of user terminals to access data resources may be changed arbitrarily, which reduces the security of data resources in the database and also Reduced security for user terminal access
