APPARATUS FOR AND METHOD OF RESTRICTING ACCESS TO FILE CONTENT AND TO MEMORY

摘要

UIMID of a UIM (50) owned by the owner of a portable phone (40) is stored in an owner information registration area (410b) of phone (40). A CPU (405) of portable phone (40), upon receiving content, compares a UIMID of a UIM (50) inserted in phone (40) to the UIMID registered in owner information registration area (410b). The storing of the content in a non-volatile memory (410) is permitted only when the two UIMIDs agree with each other.
