Abstract
In a portable card medium used for an IC card capable of realizing a plurality of application functions, the portable card medium includes an accepting mechanism to accept an application processing request from a host apparatus, an area control mechanism to extract an area of a memory for processing corresponding to the application processing request accepted by the accepting mechanism, and request the executing mechanism to perform the processing in the extracted area, and an area monitoring mechanism to take as input information of an area having access during program execution in the executing mechanism, and monitor whether or not the processing in the executing mechanism is performed in the area extracted by the area control mechanism, thereby preventing data to be managed by other application functions from being fetched.
