摘要:
The present invention provides a method for making it more convenient for a user to try out contents. When contents are received, the contents are written in a free space or a space where some data is already stored, of cache memory means (409a). When contents are written in the cache memory means, the contents are processed or executed. When a command is issued using operation means for storing contents processed or executed, the contents are read from the cache memory means (409a), and written in content storage means.

A mobile phone compares a URL of a provider of an original Java application (JavaAP) with a URL of a provider of a destination JavaAP, to determine whether a FQDN (Fully Qualified Domain Name) of the URLs are identical. Only if the FQDNs are identical, the mobile phone permits the destination JavaAP to use data relating to the original JavaAP. In this way, appropriate management of transferring data from an application to another will be effected, thereby improving data security against an unauthorized application.

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 terminal 10 has a noncontact IC module 12 incorporating an IC chip 11; a slot 13 in which a UIM 20 is to be loaded, the UIM 20 storing connection information to be used for connection between the host terminal 10 and a mobile communication network; a memory unit 15 for storing information to identify UIM 20; an acquiring unit 16 for acquiring information to identify UIM 20 loaded in the slot 13; a comparing unit 17 for making a comparison between the information to identify the UIM 20, stored in the memory unit 15, and the information to identify the UIM 20, acquired by the acquiring unit 16; and a control unit 18 for controlling access to the IC chip 11, based on a result of the comparison by the comparing unit 17.

A communication method in a communication system includes a terminal unit, an information providing server unit, and an administering server unit, the information providing server storing an entity file including a program executed by the terminal unit, the administering server unit storing a security descriptive file including authorization information and first location information, the authorization information being used to control access by the program to at least one of a hardware resource, a network resource, and a software resource, the first location information including storage location information on the entity file. The communication method comprises: transmitting, by the administering server unit, the security descriptive file to the terminal unit; transmitting, by the information providing server, the entity file to the terminal unit in response to a request for the entity file sent from the terminal unit after receipt of the security descriptive file at the terminal unit, the storage location of the entity file being identified based on the first location information included in the security descriptive file; and controlling, when the terminal unit executes the program included in the entity file, access to the at least one resource on the basis of the authorization information included in the security descriptive file.
摘要:
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 (18). Before a mobile station runs a Java-APP which is installed in the mobile station, the mobile station accesses management server device (18) and 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.
