Abstract

According to one embodiment, an IC card (2) includes a communication unit (25), data memory (22), selector (21), and inheriting unit (21). The communication unit performs data communication with an external apparatus. The data memory stores files managed by a hierarchical structure, a folder as an upper layer of the files, and information concerning the inheritance of a security status between a plurality of folders. If the communication unit receives a command requesting the selection of a second folder while a first folder is selected, the selector sets the first folder in an unselected state, and sets the second folder designated by the command in a selected state. If information indicating the inheritance of a security status from the first folder to the second folder exists, the inheriting unit inherits, even while the second file is selected, the security status established while the first folder is selected.
