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.

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.

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.

35. The smartphone of claim 1 in which the virtual card depicts an identification document.

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.
