Abstract

A method and system supporting web file sharing transactions via a networked handheld computer system. In a system having a server that automatically detects when new versions of currently used applications are made available for a networked handheld computer system, a method is described for allowing one handheld computer system to facilitate the transfer of a file to another handheld computer system using the server. On the server, each registered handheld has account information indicating the applications (and versions) that it supports. As part of the file sharing transaction, using a token, a sending handheld computer system updates the account information of a receiving handheld to indicate that a download is required the next time the receiving handheld is networked with the server. A new file name may be recorded in the account information, or, a new version of an existing file name may be updated. The new information is then automatically downloaded to the receiving handheld during its next synchronization with the server. Security options on the receiver are available that restrict which handhelds have authority to send files to the receiving handheld. Synchronization can be performed with a host computer system, or directly between the server and the handhelds. The shared file may be any information, e.g., an application, data, images, electronic currency, etc.

Claims

1. A method of transferring information comprising the steps of:

a) at a remote server, responsive to a receiving signal from a first mobile computing device, accessing an account stored on said remote server, said account reserved for a second mobile computing device, said account describing information that is not stored in said second mobile computing device;

b) modifying said account to identify an information that resides on said remote server but not on said second mobile computing device;

c) responsive to establishing a connection with said second mobile computing device, said remote server automatically determining from said account that said information is new to said second mobile computing device, and in response to said determining, automatically downloading said information to said second mobile computing device.

2. A method as described in claim 1 further comprising the step of said remote server receiving a token identifying said information and said second mobile computing device, and wherein said token causes said account to be modified by said remote server.

3. A method as described in claim 1 wherein said first and said second mobile computing devices are portable electronic computer systems.

4. A method as described in claim 1 wherein said information is a version of an application program.

5. A method as described in claim 4 wherein said account comprises an application version record table comprising an entry for each application stored in said second mobile computing device and wherein each entry comprises:

an application identifier;

a version identifier; and

a user identifier.

6. A method as described in claim 1 wherein said step of automatically downloading said information to said second mobile computing device, of step c), is performed only if said first mobile computing device has authority to download to said second mobile computing device.

7. A method as described in claim 6 wherein said authority is established via an express grant of permission from said second mobile computing device to said first mobile computing device.

8. A method as described in claim 6 wherein said authority is established via a user confirmation that is made in response to a user message displayed on a display screen of said second mobile computing device.

9. A method as described in claim 1 wherein said remote server is a web based server.

10. A method as described in claim 1 wherein said step d) is performed within a synchronization process between said remote server and said second mobile computing device.

11. A method as described in claim 1 wherein said step d) is performed within a synchronization process between a host computer system and said second mobile computing device.

12. A system comprising:

a receiver mobile computing device;

a remote server containing an account reserved for said receiver mobile computing device which describes a complement of information stored in said receiver mobile computing device;

a sender mobile computing device for causing said account to be modified to identify an information that resides on said remote server but not on said receiver mobile computing device;

wherein said receiver mobile computing device is for establishing a connection with said remote server; and

wherein said remote server is for automatically determining, from said account, that said information is new to said receiver mobile computing device and automatically for downloading said information to said receiver mobile computing device.

13. A system as described in claim 12 wherein said sender mobile computing is for sending said remote server a token identifying both said information and said receiver mobile computing and wherein said token causes said remote server to modify said account.

14. A system as described in claim 12 wherein said sender and said receiver mobile computing devices are mobile computing computer systems.

15. A system as described in claim 12 wherein said information is a version of an application program.

16. A system as described in claim 15 wherein said account comprises an application version record table comprising an entry for each application stored in said receiver mobile computing device and wherein each entry comprises:

an application identifier;

a version identifier; and

a user identifier.

17. A system as described in claim 12 wherein said remote server is also for determining if said sender mobile computing device has authority to download to said receiver mobile computing device as a precursor to downloading said information to said receiver mobile computing device.

18. A system as described in claim 17 wherein said authority is established via an express grant of permission from said receiver to said sender mobile computing device.

19. A system as described in claim 17 wherein said authority is established via a user confirmation that is made in response to a user message displayed on a display screen of said receiver mobile computing device.

20. A system as described in claim 12 wherein said remote server is a web based server.

21. A system comprising:

a receiver mobile computing computer;

a web based server containing an account reserved for said receiver mobile computing computer which describes a complement of information stored in said receiver mobile computing computer;

a sender mobile computing computer for causing said account to be modified to identify an information that resides on said web based server but not on said receiver mobile computing compute;

wherein said receiver mobile computing computer is for establishing a connection with said web based server; and

wherein said web based server automatically determines, from said account, that said information is new to said receiver mobile computing computer, also determines if said sender mobile computing computer has authority to download to said receiver mobile computing computer, and if so, automatically downloads said information to said receiver mobile computing computer.

22. A system as described in claim 21 wherein said sender mobile computing is for sending said remote server a token identifying both said information and said receiver mobile computing and wherein said token causes said web based server to modify said account.

23. A system as described in claim 21 wherein said information is a version of an application program.

24. A system as described in claim 21 wherein said account comprises an application version record table comprising an entry for each application stored in said receiver mobile computing computer and wherein each entry comprises:

an application identifier;

a version identifier; and

a user identifier.
