An information processing device, such as a tablet computer or a smartphone, executes diverse processes by an intuitive operation combining a stylus pen and a finger in an input operation of information for performing the startup of an application program, the search for or editing of information, or the like. The information processing device is provided with an information input control program that identifies a first input such as a stylus pen and a second input such as a finger, identifies information input by the first input, recognizes a region designated by the second input, and from the information identified in the recognized region, executes a predetermined process that starts an application program, or searches for or edits information. It is possible to execute diverse processes an intuitive operation using two inputs.

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 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

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.

Server devicestores contract identification information with UIM (Universal Identity Module) identification information for identifying a UIMissued in accordance with a subscription contract between a subscriber and a communication carrier for services provided by the communication carrier, the contract identification information identifying the subscription contract. The UIMstores UIM identification information. After receiving the UIM identification information from the mobile station, which obtained the UIM identification information from UIM, server devicetransmits the contract identification information corresponding to the UIM identification information to the mobile station. Then the contract identification information is stored in UIM. Consequently, the present invention allows a communication apparatus to distinguish a user who attempts to use the communication apparatus.

Server device, communication device, and program for managing contents usage

Mobile terminal receives from a server a content, a sending time information which indicates the time of sending the content, and a time restriction information that indicates the time period when the content can be used. Mobile terminal correlates the content with the sending time information and the time restriction information, and stores them. Mobile terminal calculates the difference between the time of receiving the content and the sending time information. Mobile terminal correlates the difference with the content and stores them. Mobile terminal adds the difference to the current time kept by time keeping unit to obtain a usage determination reference time. Mobile terminal compares the usage determination reference time with the time restriction information to determine whether the mobile terminal can use the content or not.
