UIMID of a UIMowned by the owner of a portable phoneis stored in an owner information registration areaof phone. A CPUof portable phone, upon receiving content, compares a UIMID of a UIMinserted in phoneto the UIMID registered in owner information registration area. The storing of the content in a nonvolatile memoryis permitted only when the two UIMIDs agree with each other.

System for restricting content access and storage

Mobile unitwhich can activate Java-AP software receives SDF (Security Descriptive File)from administering server unitwhich a trustworthy organization (a communication provider which administers mobile packet communication network) administers, and obtains ADFfrom IP server unitby using URL contained in the SDF, and obtains Jar filefrom IP server unitby using ADF, and installs in itself Java-AP containing these files. Java-AP, which is achieved by activating the installed Java-AP software, operates within the range of authorization expressed by policy information contained in SDF

Contents transmission method and contents transmission system

An object is to provide a service providing method capable of curbing rise of cost A service providing method according to the present invention is one for providing services A and B, which authenticates a user of an authentication requesting terminal in order to make service A available to the user and which determines whether service B is available to the user, in a state in which the user is authenticated about service A. When service B is determined to be available, a permission message is stored and a permission response based on the permission message for utilization of service B is transmitted to the authentication requesting terminal. Then the permission message on which a utilization request message from a service utilizing terminal is based, is verified, and, if it is in an available status, the service utilizing terminal is permitted to utilize service B. The use of the authentication result on service A obviates a need for provision of a new authentication for service B, so as to lead to reduction of cost.

Device and method for restricting content access and storage

Mobile unitwhich can activate Java-AP software obtains ADFfrom IP server unit, receives SDF (security descriptive file)by using ADFfrom administering server unitwhich a trustworthy organization (a communication provider which administers mobile packet communication network) administers, and obtains Jar fileby using ADFfrom IP server unit. Then, mobile unitinstalls Java-AP software containing these files. Java-AP, which is achieved by activating the installed Java-AP software, operates within the range of authorization expressed by policy information contained in SDF
