ABSTRACT:
An objective is to prevent an unauthorized application from falsifying and assuming specific information generated for access to an external memory, without permission, and to achieve safer management of access to the external memory. An external memory function module15is a function module to control access of applications101A and101B downloaded in a cell phone1, to an external memory2. This external memory function module15has an identifier acquirer151for acquiring an identifier from each of the applications101A and101B, a generator153for generating specific information to specify the application, based on identification information designated by the identifier acquired, a reserving section154for reserving a predetermined area of the external memory2as a directory for the application, and a writing section155for writing the specific information generated, in an attribute file of the external memory2.
