Abstract

The invention provides an object-label-based data protection method and the execution device, including the following steps: according to user information, generate user's security licensing; when generate data, grant the data security labels according to user's security licensing; during accessing data, determine whether the user has the authority to access the data according to the user's security licensing and the data security labels. It improves the problem and deficiency of the existing data protection methods, and provides more security for the data.

Description

Technical field [0001] The present invention relates to data security protection technology, in particular to a data protection technology in a multi-user database management system (DBMS), and specifically to a data protection method and execution device based on object tags. Background technique [0002] Data security has always been a concern in database systems. Data security in the database refers to protecting the data in the database from damage, alteration or leakage. Data protection methods refer to measures taken to protect data security. [0003] The usual data protection methods are: [0004] Autonomous access control: Give users the authority to read, write, modify, and delete data, and users with authority can perform corresponding operations on the data. The disadvantage of this method is that the granularity of data access control is table-level or column-level, and the granularity is relatively coarse. Summary of the invention [0005] The purpose of the present...
