Abstract

The presently claimed invention relates generally to steganography and fingerprinting or hashing. In one embodiment, a method includes: obtaining a first set of plural-bit data, the first set of plural-bit data corresponding to at least a portion of steganographically encoded data in a media signal in the form of a digital watermark; obtaining a second set of plural-bit data, the second set of pural-bit data corresponding to a fingerprint or hash of the media signal. THe fingerprint or hash includes a reduced-bit representation of the media signal, and the first set of plural-bit data is not dependent on information in the second set of plural-bit data. The method further includes carrying out a first action associated with the first set of plural-bit data; and carrying out a second action associated with the second set of plural-bit data. Other embodiments are described and claimed as well.

wherein the digital watermark is formed independently of the hash or fingerprint;

executing a first action based on the plural-bit data; and

executing a second action based on the hash or fingerprint.

2. The method of claim 1, wherein said decoding, deriving, executing a first action and executing a second action are also performed in one or more computer servers.

3. The method of claim 1, wherein at least one of the decoding and deriving are performed in a user device, and said method further comprises communicating the plural-bit data and the fingerprint to a server.

4. The method of claim 1 wherein the second action comprises identifying a memory location or metadata associated with the plural-bit data.

5. The method of claim 1 where at least one of the first action or the second action comprises searching one or more databases.

6. The method of claim 1 wherein at least one of the first action or the second action comprises content monitoring

7. The method of claim 1 wherein the first action or the second action comprises accessing promotional information.

8. The method of claim 1 wherein the digital watermark is embedded in the signal by an embedding clearinghouse.

9. The method of claim 1 wherein the first action or the second action is conditioned on user input.

10. A physical computer readable medium comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the method of claim 1.

11. A physical programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 1.

12. A programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 4.

13. A method comprising:

obtaining a first set of plural-bit data, the first set of plural-bit data corresponding to at least a portion of steganographically encoded data in a media signal in the form of a digital watermark;

obtaining a second set of plural-bit data, the second set of plural-bit data corresponding to a fingerprint or hash of the media signal, the fingerprint or hash being obtained by utilizing Viterbi decoding, wherein the fingerprint or hash comprises a reduced-bit representation of the media signal, and wherein the first set of plural-bit data is not dependent on information in the second set of plural-bit data;

using at least a programmed electronic processor, carrying out a first action associated with the first set of plural-bit data; and

using at least a programmed electronic processor, carrying out a second action associated with the second set of plural-bit data, the second action utilizes the second set of plural-bit data to at least identify the media signal or information related thereto.

14. The method of claim 13 wherein the first action comprises identifying a memory location or metadata associated with the first plural-bit data.

15. The method of claim 13 wherein at least one of the first action or the second action comprises searching one or more databases.

16. The method of claim 13 wherein at least one of the first action or the second action comprises content monitoring.

17. The method of claim 13 wherein the first action or the second action comprises accessing promotional information.

18. The method of claim 13 wherein the digital watermark is embedded in the media signal by an embedding clearinghouse.

19. The method of claim 13 wherein the first action or the second action is conditioned on user input.

20. A physical computer readable medium comprising instructions stored thereon to cause a multi-purpose electronic processor to perform the method of claim 13.

21. A programmed computing device storing instructions in memory, said instructions are executable by said programmed computing device to perform the acts of claim 13.

22. A method comprising:

obtaining data representing a media signal;

utilizing a configured multi-purpose electronic processor, performing a first operation on the data representing the media signal to obtain a first set of plural-bit data there from; and

based at least in part on a result of said act of performing a first operation on the data representing the media signal, determining whether to perform a second operation to obtain a second set of plural-bit data from the data representing the media signal,

where the first et of plural-bit data or the second set of plural-bit data is derived with a hash or fingerprint of the data representing the media signal while the other of the first set of plural-bit data or the second set of plural-bit data is associated with steganographically hidden data,

where information contained in steganographically hidden data is not dependent on information derived with a hash or fingerprint.

23. The method of claim 22 comprising performing the second operation to obtain the second set of plural-bit data from the data representing the media signal when determined based at least in part on the first set of plural-bit data.
