Abstract

A multimedia device or other type of processing device comprises a memory, a processor coupled to the memory, and playback circuitry coupled to the processor. In one aspect, the processor is operative to control the storage in the memory of at least one multimedia file containing a one-time password or other type of password, where the password is generated externally to the processing device, and to control the playback of the multimedia file via the playback circuitry to make the password apparent to or otherwise accessible to an associated user or other entity. The multimedia file may comprise, for example, an audio file, with the password being presented to the user in an audible form upon playback of the audio file. As another example, the multimedia file may comprise a video file, with the password being presented to the user in a visible form upon playback of the video file.

Claims

1. A processing device comprising:

a memory;

a processor coupled to the memory; and

playback circuitry coupled to the processor;

the processor being operative to control the storage in said memory of at least one multimedia file containing a password, where the password is generated externally to the processing device, and to control the playback of the multimedia file via the playback circuitry to make the password accessible to an associated entity.

2. The processing device of claim 1 wherein the associated entity comprises a user of the processing device.

3. The processing device of claim 1 wherein the associated entity comprises a computer proximate to the processing device.

4. The processing device of claim 1 wherein the password comprises a one-time password.

5. The processing device of claim 1 wherein said device comprises a portable multimedia player.

6. The processing device of claim 2 wherein said multimedia file comprises an audio file and the password is presented to the user in audible form.

7. The processing device of claim 1 wherein said playback circuitry comprises audio playback circuitry.

8. The processing device of claim 1 wherein the processing device is configured to download the multimedia file containing the password from a computer coupled to a network.

9. The processing device of claim 1 wherein the password is generated externally to the processing device as a function of an index value and a secret seed.

10. The processing device of claim 1 wherein the password is generated externally to the processing device as a function of a time value and a secret seed.

11. The processing device of claim 2 further comprising a user interface configured to permit the user to select for playback a particular one of a plurality of multimedia files stored in the memory and containing respective passwords.

12. The processing device of claim 2 wherein the device is operative to provide the user with an indication of which of a plurality of multimedia files stored in the memory and containing respective passwords should be selected for playback at a given point in time.

13. The processing device of claim 1 wherein the memory stores a plurality of multimedia files containing respective passwords.

14. The processing device of claim 13 wherein the multimedia files containing respective passwords are stored in the form of a hierarchy.

15. The processing device of claim 2 wherein the multimedia file containing the password also contains a user guidance message that is made apparent to the user when the multimedia file is played back via the playback circuitry.

16. The processing device of claim 2 wherein the multimedia file containing the password also contains at least one advertisement that is made apparent to the user when the multimedia file is played back via the playback circuitry.

17. The processing device of claim 1 wherein the multimedia file further comprises information which specifies at least one limitation regarding conditions under which the password may be utilized.

18. The processing device of claim 2 wherein the processing device is configured to permit the user to select among a plurality of different presentation styles for presentation of the password by the processing device.

19. The processing device of claim 1 wherein the multimedia file is delivered to the processing device via a media broadcast channel.

20. The processing device of claim 1 wherein a file name of the multimedia file includes at least a portion of the password.

21. The processing device of claim 2 wherein the multimedia file comprises a video file and the password is presented to the user in a visible form.

22. A processing device comprising:

a memory; and

a processor coupled to the memory;

the processor being operative to control the storage in said memory of at least one multimedia file containing a password, where the password is generated externally to the processing device, and to control the transfer of the multimedia file to another processing device so as to make the password accessible to the other processing device.

23. A processing device comprising:

a memory;

a processor coupled to the memory; and

playback circuitry coupled to the processor;

the processor being operative to convert a password generated externally to the processing device into a multimedia file that is played back by the playback circuitry to make the password accessible to an associated entity.

24. A method of providing a password via a processing device, the method comprising the steps of:

storing in the processing device at least one multimedia file containing a password where the password is generated externally to the processing device; and

playing back the multimedia file on the processing device to make the password accessible to an associated entity.

25. The method of claim 24 wherein the associated entity comprises a user of the processing device.

26. The method of claim 25 wherein the multimedia file comprises an audio file and the password is presented to the user in an audible form.

27. The method of claim 25 wherein the multimedia file comprises a video file and the password is presented to the user in a visible form.

28. A machine-readable storage medium storing one or more software programs for use in providing a password via a processing device, wherein the one or more software programs when executed by the processing device implement the steps of the method of claim 24.
