Abstract

The present invention relates to digital watermarking methods and systems. In one embodiment, a handheld device displays a digitally watermarked image at an event center. An optical scanner captures optical scan data representing the device display. A watermark decoder analyzes the captured optical scan data to obtain the watermark. The watermark is used to determine authorized entry. The handheld device may include a cell phone or other portable computing device.

Claims

1. A method comprising:

capturing image data or video data from a handheld computing device, wherein the captured image data or video data corresponds to an image or video that is displayed via a display of the handheld computing device, wherein the image data or video data comprises a digital watermark comprising information, wherein the digital watermark is embedded in the image data or video data through alterations to visually perceptible elements of the image data or video data, and wherein the digital watermark is visually imperceptible to a human observer;

analyzing, using a processor, the image data or video data to derive the information; and

triggering an action based at least in part on the information.

2. The method of claim 1, wherein the action comprises applying a credit or coupon to a purchase.

3. The method of claim 1, wherein the action comprises regulating entry to an event, movie or secure area.

4. The method of claim 1, wherein the action comprises controlling inventory.

5. The method of claim 1, wherein the action comprises providing verification aids for seeing impaired.

6. The method of claim 1, wherein the action comprises engaging a document management system.

7. The method of claim 1, wherein the handheld computing device comprises a cell phone.

20. The method of claim 1, further comprising:

determining an authenticity of the image data or video data based on a second digital watermark, wherein the image data or video data further comprises the second digital watermark, wherein the second digital watermark is lost when the image data or video data is processed, wherein the second digital watermark is embedded in the image data or video data through alterations to visually perceptible elements of the image data or video data, and wherein the second digital watermark is visually imperceptible to a human observer.

8. An apparatus comprising:

a capture device configured to capture image data or video data from a handheld computing device, wherein the captured image data or video data corresponds to an image or video that is displayed via a display of the handheld computing device, wherein the image data or video data comprises a digital watermark comprising information, wherein the digital watermark is embedded in the image data or video data through alterations to visually perceptible elements of the image data or video data, and wherein the digital watermark is visually imperceptible to a human observer; and

a processor configured to;

analyze the captured image data or video data to derive the information; and

trigger an action based at least in part on the information.

9. The apparatus of claim 8, wherein the action comprises applying a credit or coupon to a purchase.

10. The apparatus of claim 8, wherein the action comprises regulating entry to an event, movie or secure area.

11. The apparatus of claim 8, wherein the action comprises controlling inventory.

12. The apparatus of claim 8, wherein the action comprises providing verification aids for seeing impaired.

13. The apparatus of claim 8, wherein the action comprises engaging a document management system.

14. A non-transitory computer-readable medium having instructions stored thereon, the instructions comprising:

instructions to capture image data or video data from a handheld computing device, wherein the captured image data or video data corresponds to an image or video that is displayed via a display of the handheld computing device, wherein the image data or video data comprises a digital watermark comprising information, wherein the digital watermark is embedded in the image data or video data through alterations to visually perceptible elements of the image data or video data, and wherein the digital watermark is visually imperceptible to a human observer;

instructions to analyze the captured image data or video data to derive the information; and

instructions to trigger an action based at least in part on the information.

15. The non-transitory computer-readable medium of claim 14, wherein the action comprises applying a credit or coupon to a purchase.

16. The non-transitory computer-readable medium of claim 14, wherein the action comprises regulating entry to an event, movie or secure area.

17. A method comprising:

receiving audio data rendered by a handheld computing device, wherein the audio data comprises a digital watermark comprising information, and wherein the digital watermark is embedded in audio data through alterations to audibly-perceptible elements of the audio data;

analyzing, using a processor, the received audio data to derive the information; and

triggering an action based at least in part on the derived information.

18. The method of claim 17, wherein the action comprises applying a credit or coupon to a purchase.

19. The method of claim 17, wherein the action comprises regulating entry to an event, movie or secure area.
