A secure element (SE) unitholding service data used by an application is provided in a UIM card. Thus, when the user identify module (UIM) cardis transferred between portable terminals, service data and accompanying information of the application can be moved together with the UIM cardto another portable terminal. In addition, an access management unitincluded in a portable terminalcompares UIM information of a UIM information storage unitwith UIM information, held by an authority information holding unit, of a UIM card of which use authority is possessed by an application. If they do not agree, access to service data stored in the SE unitis restricted.

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

A mobile terminal capable of causing the user side to grasp whether or not a credit settlement service stops with a simple operation is provided. In the mobile terminal, validation and invalidation of a storage area within an IC chip assigned to an issuer application corresponding to one issuer are switched based on switching instruction information received from an issuer terminalmanaged by one issuer. Then, when the issuer application starts, there is displayed in a lump whether or not the respective issuer applications are available on a display part, based on state information indicating whether or not the respective storage areas are validated. Therefore, in the mobile terminal, even if plural issuer applications are stored, it is possible to cause the user side to grasp which kind of the credit settlement service stops, with a simple operation of only starting a management application.

An objective is to prevent a downloaded application from accessing data in an external memory unrelated to the application, and to achieve safer management of access to the external memory. An external memory function moduleis a function module that controls access of an application downloaded in a cell phone, to an external memory. This external memory function modulehas a bind ID acquirerfor acquiring a bind ID to specify the application downloaded, a discrimination ID acquirerfor acquiring a directory discrimination ID to specify an application permitted to access a directory, and an access controllerfor checking the bind ID against the directory discrimination ID and for, when they coincide with each other, performing such control as to permit access of the application to the directory.

External memory management apparatus and external memory management method

An object of the present invention is to surely and readily prevent unauthorized use of a noncontact IC function incorporated in a mobile communication terminal, even in a state in which no signal can be sent through mobile communication to the mobile communication terminal. A mobile communication terminalhas a noncontact IC moduleincorporating an IC chip; a slotin which a UIMis to be loaded, the UIMstoring connection information to be used for connection between the host terminaland a mobile communication network; a memory unitfor storing information to identify UIM; an acquiring unitfor acquiring information to identify UIMloaded in the slot; a comparing unitfor making a comparison between the information to identify the UIM, stored in the memory unit, and the information to identify the UIM, acquired by the acquiring unit; and a control unitfor controlling access to the IC chip, based on a result of the comparison by the comparing unit

Mobile communication terminal and terminal control method

The present invention provides an information processing device for estimating usage of contents and properly limiting functions realized through use of the contents in accordance with the estimation. Usage of contents is estimated by determining in which of cache memory means and content storage means the contents are stored. When the contents are processed or executed, it is determined whether to limit functions realized through processing or execution of the contents, on the basis of the estimated usage of the contents and function limit information showing a rule regarding limits on functions realized through processing or execution. On the basis of the determination, the functions realized through processing or execution of the contents are limited.

Information processing device and program

A mobile communication terminal comprises: a download portion which downloads an application program from an outside WWW server, and secures a data region for reference parameters to which the application program refers at the time of execution; a control signal receiving portion which receives a control signal containing the reference parameters to which the application program refers, and a parameter saving portion which saves the reference parameters contained in the control signal to the data region.

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 moduleis a function module to control access of applicationsA andB downloaded in a cell phone, to an external memory. This external memory function modulehas an identifier acquirerfor acquiring an identifier from each of the applicationsA andB, a generatorfor generating specific information to specify the application, based on identification information designated by the identifier acquired, a reserving sectionfor reserving a predetermined area of the external memoryas a directory for the application, and a writing sectionfor writing the specific information generated, in an attribute file of the external memory

When an application is activated, a mobile stationdetects external devicesas candidates for a BLUETOOTH connection out of external devices existing in the surrounding area, and presents a list of the devices to a user. When the user selects from the list an external devicewith which a connection is to be attempted to make, a link is established by a connection procedure according to a security level described in an ADF of the application. Namely, when 'high' is described as the security level, an authentication process and an encryption process requiring input of a PIN are executed prior to the establishment of the link. On the other hand, when 'low' is described as the security level, a link is established without executing these processes.

It is an object of the present invention to provide a communication device, a digital signature verification method, and a digital signature generation method, in which the memory usage efficiency is improved without confidential information required for the verification or generation of a signature being easily leaked to the outside. The Java application judges whether signature verification is required for the received signature target data. When judging that signature verification is required, the Java application outputs the received signature target data to the PKI of the platform. The PKI verifies the signature that has been added to the data output by the Java application and performs signature generation, and then notifies the Java application.

In a terminal device equipped with a function of running an application program, operation of an application program is suspended when an event is detected, the type of the event is predetermined, and event data representing the detected event is stored. Then, the terminal device delivers stored event data to the application program, after the suspended application is resumed.

In the mobile telephonerelating to the present invention, a control sectionperforms control for switching between a non-active state which refuses inputs to an application program, and a rest state in which the application program is temporarily halted. The control sectionperforms control for switching the execution state of the application program from the non-active state to the rest state, in accordance with instructions from an input section. The control sectionfurther performs control for switching the execution state of the application program from the non-active state to the rest state, in accordance with a function contained in an application program.
