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 module 15 is a function module to control access of applications 101A and 101B downloaded in a cell phone 1, to an external memory 2. This external memory function module 15 has an identifier acquirer 151 for acquiring an identifier from each of the applications 101A and 101B, a generator 153 for generating specific information to specify the application, based on identification information designated by the identifier acquired, a reserving section 154 for reserving a predetermined area of the external memory 2 as a directory for the application, and a writing section 155 for writing the specific information generated, in an attribute file of the external memory 2.
