Abstract

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.

said storing means stores at least a part of said transmission origin address data as source data of said application.

23. A portable terminal according to claims 1 or 13 wherein:

said executing means creates, in operations executed in accordance with said first application, related data that is related to said first application

24. A portable terminal according to claims 1 or 13 further comprising:

acquiring means that acquires, before said executing means executes startup operations for said second application following startup instruction included in related data related to said first application, permission-prohibition data indicating whether it is permissible for said executing means to executes said startup operations, wherein

said executing means executes, in the case where permission-prohibition data acquired by said acquiring means indicates that it is permissible for said startup operations to be executed, said startup operations.

25. A portable terminal according to claims 1 or 13 wherein:

said receiving means receives, following an instruction of said executing means, indication data that indicates one of said plurality of applications;

said executing means executes, in the case where said receiving means received, following an instruction of said executing means in accordance with said first application, indication data that indicates said second application, executes startup operations for said second application.

13. A portable terminal comprising:

receiving means that receives data from external electronic devices through wireless communications networks;

storing means that store (a) a plurality of applications including at least a first application and a second application, (b) related data that has been related to said plurality of applications respectively and (c) source data that indicates sources of said related data respectively;
