Electronic device, methods, programs and storage media for data management

The present invention relates to an electronic device (MS), comprising storing means (212, 213, 214) that stores data and a program, executing means (211) that executes the program; wherein the storing means is adapted to store a first application, a second application, and an application manager (JAM), the first application is adapted to generate data and to startup the second application, and the second application includes a body (JAR file) and a descriptive file (ADF). The descriptive file (ADF) includes startup trusted source data indicating at least one trusted transmission origin address of HTML data and delivery trusted source data indicating at least one trusted transmission origin address of an application program. If the executing means (211) instructs, by executing the first application, to startup the second application, the executing means (211) is adapted to read, by executing the application manager, the startup trusted source data from the descriptive file (ADF) stored in the storing means (212, 213, 214). Further, if the executing means (211) instructs, by executing the first application, to startup the second application, the executing means (211) is adapted to read, by executing the application manager, the delivery trusted source data from the descriptive file (ADF) stored in the storing means (212, 213, 214). Still further, if a part inside a server address included in the startup trusted source data coincides with a transmission origin address of the first application and if a part inside a server address included in the delivery trusted source data coincides with the transmission origin address of the first application, the executing means (211) is adapted to startup, by executing the application manager, the second application and to deliver the generated data to the second application.
