Abstract

The disclosure relates to digital signal processing such as digital watermarking, and the utilization of portable devices (e.g., smartphones) for such signal processing. One claim recites a smartphone comprising: a touch screen display; memory for storing a payload and for storing a digital image depicting a virtual card; means for processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of outputs corresponding to the payload; means for embedding a first of the plurality of outputs in a first version of the digital image and proceeding with embedding until each of the plurality of outputs are respectively embedded in one of a plurality of versions of the digital image; and means for displaying embedded versions of the digital image so that a receiver analyzing captured image data representing the touch screen display can recover the payload. Of course, other claims and combinations are disclosed too.

First claim

What is claimed is:

1. A smartphone comprising:
a touch screen display;
a microphone for capturing ambient audio;
memory for storing an image, the image depicting a virtual card; and
one or more processors configured for:
obtaining versions of the stored image;
accessing a payload;
processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of components, the plurality of components corresponding to the payload;
embedding one of the plurality of components in a version of the stored image and proceeding with embedding until each of the plurality of components is embedded in a version of the stored image, in which the embedding utilizes digital watermarking;
causing the touch screen display to display a plurality of embedded image versions so as to cause a static image display effect of the virtual card, the displayed embedded image versions being displayed by the smartphone.

2. The smartphone of claim 1 in which the accessing comprises generating the payload based on user input.

3. The smartphone of claim 1 in which said one or more processors are configured to operate as the erasure code generator, and in which the erasure code generator comprises a fountain code generator, in which the fountain code generator produces the plurality of components, from which a receiver can reassemble the payload by obtaining a subset of the plurality of components, the subset comprising less components than the plurality of components.

4. The smartphone of claim 1 in which only one component of the plurality of components is embedded in any one image version.

5. The smartphone of claim 1 in which said one or more processors are configured for: i) generating a perceptibility map of the image, ii) storing the perceptibility map in said memory, and iii) reusing the perceptibility map when embedding the plurality of components in corresponding image versions.

6. The smartphone of claim 1 further comprising an audio transmitter, in which said one or more processors are configured to cause said audio transmitter to transmit an audio signal.

7. The smartphone of claim 6 in which said audio transmitter comprises a high frequency audio transmitter.

8. The smartphone of claim 6 in which the audio signal comprises a pin, key or hash.

9. The smartphone of claim 1 in which the plurality of components comprises a subset of a total number of components provided by the erasure code generator.

10. The smartphone of claim 2 in which said one or more processors are configured to interpret the user input which is received via said touch screen display.

11. A method employing a smartphone, the smartphone including a touch screen display, and one or more processors, the method including acts of:
obtaining a payload;
using the one or more processors, processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of components corresponding to the payload;
obtaining versions of a digital image, the digital image depicting a virtual card;
using the one or more processors, embedding one of the plurality of components in a version of the digital image and proceeding with embedding until each of the plurality of components is embedded in a version of the digital image, in which the embedding utilizes digital watermarking;
causing the touch screen display to sequentially display embedded digital image versions so as to cause a static image display effect, the displayed embedded digital image versions being displayed by the smartphone.

12. The method claim 11 in which the obtaining a payload comprises generating the payload based on user input.

13. The method of claim 11 in which the erasure code generator comprises a fountain code generator, in which the fountain code generator produces the plurality of components, from which a receiver can reassemble the payload by obtaining a subset of the plurality of components, the subset comprising less components than the plurality of components.

14. The method of claim 11 in which only one component of the plurality of components is embedded in any one digital image version.

15. The method of claim 11 further comprising: i) generating a perceptibility map of the digital image, ii) storing the perceptibility map in memory, and iii) reusing the perceptibility map when embedding the plurality of components in digital image versions.

16. The method of claim 11 , in which the smartphone comprises an audio transmitter, said method further comprising transmitting an audio signal, said transmitting using the audio transmitter.

17. The method of claim 16 in which the audio transmitter comprises a high frequency audio transmitter.

18. The method of claim 16 in which the audio signal comprises a pin, key or hash.

19. The method of claim 11 in which the plurality of components comprises a subset of a total number of components provided by the erasure code generator.

20. The method of claim 11 in which the embedded digital image versions are displayed so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload.

21. A method employing a smartphone, the smartphone including a touch screen display, and one or more processors, the method including acts of:
obtaining a payload;
processing the payload with an erasure code generator, in which the erasure code generator produces a plurality of outputs corresponding to the payload;
obtaining a digital image, the digital image depicting a virtual card;
utilizing the one or more processors, embedding one of the plurality of outputs in a version of the digital image and proceeding with embedding until each of the plurality of outputs is embedded in a version of the digital image, in which the embedding utilizes digital watermarking;
causing the touch screen display to display a plurality of embedded versions of the digital image so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload.

22. The method of claim 21 in which the erasure code generator comprises a fountain code generator.

23. The smartphone of claim 1 in which said one or more processors are configured to cause the embedded image versions to be displayed so that a digital watermark reader analyzing captured image data representing the touch screen display can recover the payload.

24. The method of claim 11 in which the smartphone comprises a wearable device comprising glasses or a wrist watch.

25. The method of claim 21 in which the smartphone comprises a wearable device comprising glasses or a wrist watch.

26. The method of claim 21 in which said causing the touch screen display to display embedded versions of the digital image causes different embedded versions to be cyclically displayed such that collectively the displayed embedded versions cause a static image display effect of the virtual card.

27. The method of claim 21 in which only one output of the plurality of outputs is embedded in any one image version.

28. A smartphone comprising:
a touch screen display;
memory for storing a payload, and for storing a digital image depicting a virtual card;
