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

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

A native mailer operated in accordance with a native program installed by a manufacturer of mobile phoneobtains an e-mail generated by using an application mailer. A native mailer obtains an e-mail, and stores in a folder for an application mailer, an e-mail generated by using an application mailer.

Communication terminal operational with multiple applications

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

To provide a mechanism that enables preparation of a program for photographing regardless of the type of camera device and obtaining image data in a unified format. Mobile phonecomprises: means for selecting a camera device; means for generating, in a case that image data of said object photographed by a selected camera device is to be stored, a camera object including attributes corresponding to said camera device; means for calling a program to photograph an object; means for photographing the object with said camera device in accordance with the program called by the camera function calling means and for storing image data representing image of said object in the camera object; and means for obtaining image data stored by the image storing means in a unified format from the camera object.
