Abstract
A policy determination unit acquires a rule for a request for accessing data based on a preset access control policy, and selects whether to acquire attribute information about an attribute of each record of the data from the outside of a database in which the data is stored. As a result, when selecting acquisition of the attribute information, the attribute information is acquired and the rule based on the attribute information is evaluated, and when selecting no acquisition of the attribute information, the database is caused to execute filtering of the data based on the rule. Then, based on the evaluation result of the rule or the filtering execution result, a record of the data corresponding to the access request is acquired from the database.
