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.

Mobile communication terminal and application control method

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.

Mobile station and communication control method

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.

Terminal device and program

The present invention provides a means for determining authenticity of a combination of files which are downloaded to a mobile station, and which are related to one another. To achieve the stated object, in a system according to the present invention, mobile station, which is capable of running a Java-APP, receives an ADF from CP server device. Then mobile stationreceives a SDF from trusted server device, which is identified by data contained in the ADF. Mobile stationcalculates a hash value of certificate data contained in the ADF, and verifies whether the calculated hash value of the certificate data and a hash value of the certificate data which is contained in the SDF are identical to each other. Next, mobile stationreceives a JAR file from CP server device. Mobile stationcalculates a hash value of the JAR file, and verifies whether the calculated hash value of the JAR file and a hash value of the JAR file contained in the ADF are identical to each other.

Communication device and program

The present invention provides a means for reflecting modifications made in a server to data with regard to a scope of rights, which are granted to an application program operable in a communication device such as a mobile station, on data stored in the communication device. To achieve the aim, in a system according to the present invention, Java-AP software is provided to a mobile station by transmitting an ADF, a SDF and a JAR file from servers to the mobile station in that order. The SDF is a file containing data indicating restrictions of behavior of a Java-AP in a mobile station. The SDF also contains data indicating a validity state of the SDF, namely 'valid' or 'invalid', which is managed by management server device. Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server deviceand checks whether a SDF corresponding to the Java-APP is valid. When the SDF is valid, the mobile station runs the Java-APP following the restrictions indicated in the SDF.

Communication device, control method of communication device, program and communication method

Specific commands are contained in an application program executed in a communication terminal device, and when those commands are executed, operation of the application program is suspended by the communication terminal device and the application program is upgraded.

Communication terminal device and program

The mobile telephonepertaining to the present invention comprises a memory unit, a short-range wireless unit, and a control unit. The memory unitassociates and stores an application ID, keyword, and application software. The short-range wireless unitreceives an application ID and keyword transmitted from outside. The control unitretrieves from the application storage areaand starts application software that corresponds to the received application ID when there is a match between the keyword received by the short-range wireless unitand the keyword stored in the ADF storage area
