Abstract

The presently claimed invention relates generally to methods and apparatus employing digital watermarking. Once claim recites an apparatus including: electronic memory for storing received digital imagery or audio, in which the digital imagery or audio comprises digital watermarking including a first instruction, in which the digital watermarking is hidden in the digital imagery or audio through alterations of data representing the digital imagery or through alterations of data representing the audio; and an electronic processor programmed for: decoding the digital watermark from the digital imagery or audio to obtain a first instruction; and based at least in part on the obtained first instruction, updating said apparatus when an address associated with the digital imagery or audio changes. Of course, other claims and combinations are provided too.

Claims

1. A method comprising:

receiving digital imagery or audio, wherein the digital imagery or audio comprises digital watermarking including a first instruction, wherein the digital watermarking is hidden in the digital imagery or audio through alterations of data representing the digital imagery or audio;

using at least a programmed electronic processor, decoding the digital watermarking from the digital imagery or audio to obtain a first instruction carried by or linked to the digital watermarking;

communicating the first instruction to a remotely located online site, the online site including an address associated with the digital imagery or audio, the first instruction instructs the online site to provide a future update to inform a user device when the address associated with the digital imagery or audio changes; and

based at least in part on receiving the future update, updating the user device with information contained in the future update when an address associated with the digital imagery or audio changes.

2. The method of claim 1, wherein the user device comprises a desktop searching tool.

3. The method of claim 1 wherein the digital watermarking includes a user identifier or user device identifier.

4. A non-transitory computer readable memory comprising instructions stored therein, said instructions causing an electronic processor to perform the method of claim 1.

5. A programmed computing device comprising instructions stored in memory, said instructions causing said programmed computing device to perform the method of claim 1.

6. The method of claim 1 in which a fingerprint derived from data representing the digital imagery or audio is associated in a data repository with the digital imagery or audio.

7. A non-transitory computer readable memory comprising instructions stored therein, said instructions are for causing an electronic processor to perform the method of claim 6.

8. An electronic apparatus programmed to perform the method of claim 6.

9. An electronic apparatus programmed to perform the method of claim 1.

10. The method of claim 1 in which said user device comprises a cell phone.

11. An apparatus comprising:

electronic memory for storing received digital imagery or audio, in which the digital imagery or audio comprises digital watermarking including a first instruction, in which the digital watermarking is hidden in the digital imagery or audio through alterations of data representing the digital imagery or through alterations of data representing the audio; and

an electronic processor programmed for;

decoding the digital watermark from the digital imagery or audio to obtain a first instruction;

communicating the first instruction to a remotely located online site, the online site including an address associated with the digital imagery or audio, the first instruction instructs the online site to provide a future update to inform a user device when the address associated with the digital imagery or audio changes; and

based at least in part on receiving the future update, updating said apparatus with information contained in the future update when the address associated with the digital imagery or audio changes.

12. The apparatus of claim 11 in which said apparatus comprises a desktop searching tool.

13. The apparatus of claim 11 in which the digital watermarking further includes a user identifier or user device identifier.

14. The apparatus of claim 11 in which a fingerprint derived from data representing the digital imagery or audio is associated in a data repository with the digital imagery or audio.

15. The apparatus of claim 11 in which said electronic processor is operating to perform at least one function recited therein.

16. A cell phone comprising the apparatus of claim 11.
