METHOD FOR CLASSIFYING DATA TO PERFORM ACCESS CONTROL, COMPUTER AND COMPUTER PROGRAM THEREFOR

摘要

PROBLEM TO BE SOLVED: To prevent reduction of usability and inhibition of user convenience due to data analysis processing in access control.

SOLUTION: Technique for classifying data to perform access control. A first piece of data as a reference for classification is extracted from data to be classified or attributes thereof and is analyzed to determine whether a predetermined first part including data to be classified or the first data belongs to a first classification category. When it is determined that the first part belongs to the category, first access control set is applied to an action to the data to be classified or the first data. When the first access control set is applied and the access control to the action to the data to be classified or the first data is suspended, a second piece of data as a reference for classification is extracted from the data to be classified or attributes thereof and analyzed to determine whether the second data belongs to a second classification category. When it is determined that the second piece of data belongs to a second classification category, a second access control set is applied to the suspended first action.
