Abstract

The present invention relates to using a portable device in association with a computing session on a host computing device. The portable device preferably includes software capable of executing on the host computing device to remove records pertaining to the computing session from the host computing device to enhance privacy associated with the computing session. Preferably, the host computing device will execute the software to delete cookies, browsing histories, preferences, favorites, and bookmarks from the host computing device'"'"'s system memory, cache, and available disk drives to minimize the amount of information about the computing session left on the host computing device.

The portable device of claim 1 wherein the software is adapted to instruct the host computing device to delete one or more of the group consisting of browsing histories, cookies, preferences, favorites, and bookmarks from one or more of the group consisting of system memory, cache, and disk drives.

5. The portable device of claim 1 wherein the software is further adapted to instruct the host computing device to automatically execute on the host computing device after the host computing device recognizes the presence of the portable device and instruct the host computing device to launch a program on the host computing device.

6. The portable device of claim 5 wherein the software is further adapted to instruct the host computing device to customize the user interface for the program for the computing session based on the data.

7. The portable device of claim 6 wherein the software is further adapted to provide an authentication routine to execute on the host computing device, the authentication routine including receiving authentication indicia from a user via an interface on the host computing device and determining if the authentication indicia received from the user matches authentication indicia stored in the memory.

8. The portable device of claim 1 wherein the software is further adapted to provide an authentication routine to execute on the host computing device, the authentication routine including receiving authentication indicia from the user via an interface on the host and determining if the authentication indicia received from the user matches authentication indicia stored in the memory.

9. The portable device of claim 1 wherein the software is adapted to emulate a file system resident on a memory device on the host computing device when interacting with the host computing device.

10. The portable device of claim 1 wherein the software and data are adapted to appear as a file system to the host computing device.

11. The portable device of claim 1 wherein the interface is adapted to directly interface a port in the host computing device.

12. The portable device of claim 1 wherein the interface is adapted to provide a wireless interface with the host computing device.

13. The portable device of claim 1 wherein the software includes a plurality of keylets that are independently executable on the host computing device to provide at least one function.

15. The portable device of claim 14 wherein the software is further adapted to instruct the host computing device to remove records pertaining to the computing session from the host computing device to enhance privacy associated with the computing session.

16. The portable device of claim 15 wherein the software is further adapted to instruct the host computing device to remove the records pertaining to the computing session from the host computing device, in association with termination of the computing session.

17. The portable device of claim 14 wherein the software is further adapted to instruct the host computing device to detect instructions from the user indicating the termination of the computing session.

18. The portable device of claim 14 wherein the software is further adapted to instruct the host computing device to detect disassociation of the portable device from the host computing device to indicate termination of the computing session.

20. The computer readable medium of claim 19 wherein the software is further adapted to detect instructions from the user indicating the termination of the computing session.

21. The computer readable medium of claim 19 wherein the software is further adapted to detect disassociation of the portable device from the host computing device to indicate termination of the computing session.

22. The computer readable medium of claim 19 wherein the software is adapted to delete one or more of the group consisting of browsing histories, cookies, preferences, favorites, and bookmarks from one or more of the group consisting of system memory, cache, and disk drives.

23. The computer readable medium of claim 19 wherein the software is further adapted to automatically execute on the host computing device after the host computing device recognizes the presence of the portable device and instruct the host computing device to launch a program on the host computing device.

24. The computer readable medium of claim 23 wherein the software is further adapted to customize the user interface for the program for the computing session based on the data.

25. The computer readable medium of claim 24 wherein the software is further adapted to provide an authentication routine to execute on the host computing device, the authentication routine including receiving authentication indicia from a user via an interface on the host and determining if the authentication indicia received from the user matches authentication indicia stored in the memory.

26. The computer readable medium of claim 19 wherein the software is further adapted to provide an authentication routine to execute on the host computing device, the authentication routine including receiving authentication indicia from a user via an interface on the host and determining if the authentication indicia received from the user matches authentication indicia stored in the memory.

28. The method of claim 27 further comprising detecting instructions from the user indicating the termination of the computing session.

29. The method of claim 27 further comprising detecting disassociation of the portable device from the host computing device and determining termination of the computing session upon detecting disassociation of the portable device from the host computing device.

30. The method of claim 27 further comprising:

a) executing an authentication function based on the software;

b) receiving authentication indicia from a user via an interface on the host; and

c) determining if the authentication indicia received from the user matches authentication indicia stored on the portable device.

31. The method of claim 30 further comprising:

a) executing the software on a host computing device;
