Abstract

PURPOSE: To raise the reliability of file protection by setting the pass word of every file or every directory in addition to an access right.
CONSTITUTION: Only a specified person among the persons of the same group or ordinary users having the access rights 3, 4 is made capable of executing the operation of the file or the directory by giving the access right of the file or the directory by means of the pass word 7 of every file or every directory. Namely, it is investigated whether the person to execute the operation of the file has the access right to the file or not, and if he has the access right, it is investigated whether the pass word 7 is set previously in the file 8 or not. If the pass word 7 is set previously, it is investigated whether the pass word 7 of the file 8 coincides with the one given at the time of the operation of the file 8 or not, and if the pass word coincides, the operation for the file 8 is performed by a step ST4. Thus, the file protection is improved.
