Description

technical field

[0001] The invention relates to an autonomous access control method for database tables, in particular to an autonomous access control method for row-level data in database tables. Background technique

[0002] Discretionary access control is the foundation of operating systems and database management systems, and an important attribute of it is the ability to support delegated authorization rules. At present, the autonomous access control of many databases is based on the access control matrix (Access Control Matrix) to realize the access control of the table level and attribute level (column level) of the role. Access controls are performed on these columns, but such access controls do not constrain access to rows in the database. For example, if a database user has access rights to a certain database table, the user can have relevant access to each row in this table. Therefore, this traditional table-level, attribute-level (column-level) granular object ...
