An IP server sends e-mail to a mobile device MS. This e-mail includes an application specifier that specifies startup of a Java application stored in mobile device MS. On the other hand, the ADF for the Java application stored in mobile device MS includes trusted source data containing a plurality of e-mail addresses that indicate trusted origins. Mobile device MS compares the e-mail transmission origin address with the trusted source data. Mobile device MS, only in the case where the transmission origin address of the received e-mail is included in the trusted source data, starts up a Java application based on an application specifier included in said e-mail.

An IP server sends e-mail to a mobile device MS. This e-mail includes an application specifier that specifies startup of a Java application stored in mobile device MS and a data specifier that includes data used in operations executed by mobile device MS in accordance with a Java application. On the other hand, the ADF for the Java application stored in mobile device MS includes trusted source data containing a plurality of e-mail addresses that indicate trusted origins. Mobile device MS compares the e-mail transmission origin address with the trusted source data. Mobile device MS, only in the case where the transmission origin address of the received e-mail is included in the trusted source data, starts up a Java application based on an application specifier included in said e-mail, and uses data included in said data specifier in operations executed by that Java application.

Application data usage management system for an electronic device

With regard to data, stored in mobile phone, whose a security level is high and contents whose copyrights are protected, mobile phoneencapsulates data and contents, and includes the encapsulated data or the encapsulated contents. Further, mobile phoneprocesses the encapsulated data as a perfect encapsulated object utilizing only a method which is not authorized access to the encapsulated data by an executed program (E.g. Downloaded Java Applications). Java AP downloaded to mobile phoneinstructs a perfect encapsulated object to process the encapsulated data in the perfect encapsulated object by using a method belonging to the perfect encapsulated object. Therefore, this invention makes it possible to ensure securities for programs to be provided through the network without losing diversifications of programs.

Communication device

An event obtaining unitobtains an event generated in an event generation unitand outputs the event to the event providing unit. When an operation mode is mode A, the event providing unitrefers to an event table Tand provides the event to an application corresponding to the event. If the event is provided to a communication AP, the communication APis launched prior to providing the event. On the other hand, when the operation mode is mode B, the event providing unitprovides the event to a Java runtime environment. In addition, the event providing unitchanges the operation mode when a switching button CB is pressed.

Method for providing event to application, and electronic device using this method

When downloading a Java&#x2122; application AP from a servera scheme and a transmission port number used by serverwhen downloading Java&#x2122; application AP are stored in addition to a host name of serverThen, when the Java&#x2122; application AP accesses a resource on the Internet, the host name of a resource to be accessed, and a scheme and a destination port number are compared with the stored host name, scheme, and transmission port number. The network access is permitted only when the compared items agree with each other.

Method and device for managing access to network

At a terminal where communication can take place via a network, ADF in which property information on data is stored is received, and based upon the communication systems (ordinary/SSL) which were used for receiving this ADF and the communication system which is used for receiving JAR in which the entity of the above mentioned data is stored, whether a communication pattern is allowable determined. JAR is received if the communication pattern is allowable, and JAR is not received if the communication pattern is not allowable for security reasons. In other words, data is obtained only when the communication pattern is allowable.
