The present invention provides a card type recording medium such as an IC card, which contains storage units to store data and an access control unit to control an access to the data by an access subject. The access control unit is designed to include an access subject identification information generating unit to generate an access subject identification information for identifying the access subject, an access authority information read-in unit to read in access authority information set in correspondence with the data that the access subject requests to access, and a control unit to obtain an access authority from the access subject identification information and the access authority information, and to control an access to the data by the access subject on the basis of the access authority obtained. Thereby, the card type recording medium intends to simplify the setting and modifying work of an access authority, and to reliably perform the management and operation of a security system.
