The present invention provides a card type recording medium such as an IC card whereby the setting and modifying work of an access authority can be simplified and the management and operation of a security system can be reliably performed. The card type recording medium (1) contains storage units (2-1 to 2-n) to store data and an access control unit (4) to control an access to the data by an access subject. The access control unit (4) is designed to include an access subject identification information generating unit (5) to generate an access subject identification information for identifying the access subject, an access authority information read-in unit (6) to read in access authority information (3-1 to 3-n) set in correspondence with the data that the access subject requests to access, and a control unit (7) to obtain an access authority from the access subject identification information and the access authority information (3-1 to 3-n), and to control an access to the data by the access subject on the basis of the access authority obtained.
