Patent Images
1. A method comprising:
- receiving a plurality of digital images over a network,each of the plurality of digital images comprising at least one digital watermark steganographically embedded therein,a digital watermark being carried in a digital image through relatively slight variations to data representing the digital image,wherein at least one digital watermark per digital image comprises a plural-bit payload;
decoding the digital watermarking from the plurality of digital images to obtain a plurality of plural-bit payloads,wherein each of the payloads comprises geolocation metadata associated with at least one area depicted in a respective digital image; and
providing a travel-log for access over the network based at least in part on the geolocation metadata.

Abstract
The present invention relates generally to digital watermarking and steganography. In one embodiment, a method is provided including: obtaining a plurality of imagery, each item of the plurality of imagery including steganographic encoding, the steganographic encoding including multi-bit data; detecting the multi-bit data from the plurality of imagery, wherein the multi-bit data is associated with geolocation metadata; and providing a geographic path associated with the plurality of imagery based at least in part on the geolocation metadata. Other embodiments are provided as well.

9. A computer comprising:
-
an input to receive a plurality of digital images, each of the plurality of digital images comprising at least one digital watermark steganographically embedded therein, the digital watermark being carried in a digital image through relatively slight variations to data representing the digital image, wherein each digital watermark comprises a plural-bit payload; a digital watermark decoder to decode digital watermarking from the plurality of digital images to obtain a plurality of plural-bit payloads, each of the payloads comprises geolocation metadata associated with at least one area depicted in a respective digital image; and a processor or executable instructions executing on electronic circuitry to determine a travel-log associated with the plurality of pictures based at least in part on the geolocation metadata; and an output to provide access to the travel-log. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A method comprising:
-
obtaining a plurality of imagery, wherein each item of imagery from the plurality of imagery comprises steganographic encoding, the steganographic encoding altering data representing the imagery, the steganographic encoding comprising multi-bit data, and wherein the presence of the multi-bit data is imperceptible to a human observer of the imagery absent machine- detection; detecting the multi-bit data from the plurality of imagery, wherein the multi-bit data is associated with geolocation metadata; providing a geographic path associated with the plurality of imagery based at least in part on the geolocation metadata. - View Dependent Claims (17, 18, 19, 20)
