Abstract

An application title, storage location information, and a download flag F is stored in an application control table TBL provided in table area 14b of EEPROM 14 of mobile phone MS. The download flag F indicates whether the application is a downloaded application. When downloading an application from IP server W, CPU 11 changes the download flag corresponding to the application to “1”. When executing the application, CPU 11 reads out the download flag F corresponding to the application and displays a predetermined image on a liquid crystal display MS4 when the download flag F has a value of “1”.

Claims

1. A terminal device comprising:

storage means for storing a plurality of applications; and

application executing means for executing an application stored in the storage means, and for giving a user a notification on the basis of a source of an application being executed.

2. A terminal device as set forth in claim 1,

wherein said application executing means determines a source of an application on the basis of an installation method of the application.

3. A terminal device as set forth in claim 1,

wherein said application executing means changes said notification on the basis of whether said application being executed is downloaded from a network.

4. A terminal device as set forth in claim 1,

wherein said application executing means changes said notification on the basis of whether said application being executed is read out from an external storage medium.

5. A terminal device as set forth in claim 2,

wherein said application executing means changes said notification on the basis of whether reliability of said application being executed is guaranteed by a third party which is different from a provider of said application.

6. A terminal device as set forth in claim 5,

wherein said application stored in said storage means includes an application downloaded from a network via a relay device;

and

said application executing means determines whether reliability of the application is guaranteed on the basis of whether there is a predetermined identifier added by said relay device.

7. A terminal device as set forth in claim 1,

wherein said storage means comprises:

first storage means for storing an application obtained from external storage medium; and

second storage means for storing a preinstalled application;

wherein said application executing means changes said notification on the basis of whether said application being executed is from said first storage means or from said second storage means.

8. A terminal device as set forth in claim 1 further comprising:

display means for displaying various information under control of said application executing means; and

wherein said application executing means displays by image on said display means said notification that differs on the basis of source of application.

9. A terminal device as set forth in claim 8,

wherein said display means display an image for an application executed by said application executing means on a first displaying area, and an image for said notification information on a second displaying area that is independent from said first displaying area.

10. A method for having a terminal device to execute an application, comprising the steps of:

causing a terminal device to download an application from a network;

causing said terminal device to store said application in a storage unit in relation to a download identifier showing that said application is a downloaded application; and

causing said terminal device, if a download identifier is related to an application when executing said application, to display a predetermined image on a displaying unit of said terminal device.

11. A method for having a terminal device to execute an application, comprising the steps of:

causing said terminal device to download an application from a network through a relay server; and

causing said terminal device, if said terminal device finds an identifier attached by a relay server on said application when executing said application, to display a predetermined image on a display of said terminal device.

12. A program product for having a computer to perform a process comprising the steps of:

downloading an application from a network by using a communication unit;

storing said application in a storage unit in relation to a download identifier showing that said application is a downloaded application; and

displaying a predetermined image on a displaying unit of said terminal device, if a download identifier is related to said application when said application is being executed.

13. A computer-readable medium for storing a program product for having a computer perform a process comprising the steps of:

downloading an application from a network by using a communication unit;

storing said application in a storage unit in relation to a download identifier showing the application is a downloaded application; and

displaying a predetermined image on a display of said terminal device, if a download identifier is related to said application when said application is being executed.

14. A relay device for relaying data between a first network and a second network, the relay device comprising:

receiving means for receiving data from said first network; and

forwarding means for forwarding data received by said receiving means to said second network, and for adding a predetermined identifier to said data when reliability of said data is not assured by a third authority that is different from the source of said data.

15. A relay device as set forth in claim 14, wherein:

data received by the receiving means from said first network is sent by a server connected to said first network; and

said forwarding means determines whether reliability of said data is assured on the basis of identification of the server that sends said data received by said receiving means.
