Abstract

The present disclosure relates generally to the technological arts of digital watermarking and fingerprinting. One claim recites a method comprising: obtaining digital data representing imagery captured with a camera; storing the digital data at a location in electronic memory; processing the digital data with a processor, said processing comprising generating a digital fingerprint of the imagery; storing the digital fingerprint of the imagery and the location in a storage repository or index; transforming the digital data with digital watermarking upon a request to output the digital imagery to a physical domain, said digital watermarking comprising a plural bit identifier; and associating the plural bit identifier with the fingerprint and location in the storage repository or index. Of course, other combinations, features and claims are disclosed as well.

First claim

We claim:

1. A method comprising:
obtaining digital data representing imagery captured with a camera;
storing the digital data at a location in electronic memory;
processing the digital data with a processor, said processing comprising generating a digital fingerprint of the imagery;
storing the digital fingerprint of the imagery and the location in a storage repository or index;
transforming the digital data with digital watermarking upon a request to output the imagery to a physical domain, said digital watermarking comprising a plural bit identifier;
associating the plural bit identifier with the fingerprint and location in the storage repository or index; and
identifying the imagery with the digital fingerprint while in a digital domain and identifying the imagery only with the digital watermarking while in the physical domain.

2. The method of claim 1 in which the imagery comprises video.

3. A system comprising:
a camera for capturing imagery;
memory for storing captured imagery;
a processor configured for:
obtaining digital data representing imagery captured with said camera;
storing the digital data at a memory location;
processing the digital data by generating a digital fingerprint of the imagery;
associating the digital fingerprint of the imagery and the memory location in a storage repository or index;
transforming the digital data with digital watermarking upon a request to output the imagery to a physical domain, said digital watermarking comprising a plural bit identifier; and
associating the plural bit identifier with the fingerprint and location in the storage repository or index; and

a detector configured for identifying the imagery with the digital fingerprint while in a digital domain and for identifying the imagery only with the digital watermarking while in the physical domain.

4. The system of claim 3 in which the imagery comprises video.

5. The system of claim 4 in which the processor is housed in a cell phone.

6. A system comprising:
a camera for capturing imagery;
memory for storing captured imagery;
a processor configured for:
obtaining digital data representing imagery captured with said camera;
storing the digital data at a memory location;
generating a digital fingerprint from the digital data representing the imagery; and
associating the digital fingerprint of the imagery and the memory location in a storage repository or index;

means for transforming the digital data with digital watermarking upon a request to output the imagery to a physical domain, said digital watermarking comprising a plural bit identifier;
in which the processor is configured for: associating the plural bit identifier with the fingerprint and location in the storage repository or index; and
means for identifying the imagery with the digital fingerprint while in a digital domain and for identifying the imagery only with the digital watermarking while in the physical domain.

7. The system of claim 6 in which the imagery comprises video.

8. The system of claim 6 in which the processor is housed within a cell phone.

9. The system of claim 6 in which the digital fingerprint comprises a reduced-bit representation of the imagery.
