Abstract

The disclosure describes methods and apparatus of providing steganographic indicia or digital watermarking in image or video data. One implementation provides a method of embedding a digital watermark in image data captured by an imager, with watermark embedding occurring on-chip with the imager. Another implementation provides a method of managing images. Each of the images comprises plural-bit data steganographically embedded therein in the form of a digital watermark, with the plural-bit data corresponding to a geo-location. Yet another implementation provides a method of identifying locations on a map, with the map being for display via a computer display. Still another implementation provides a method of introducing a watermark message to a watermark embedder located on-chip with an image array. Other implementations and embodiments are provided as well.

Claims

1. A method comprising:

receiving an image including a digital watermark embedded therein, wherein the digital watermark comprises location information;

decoding the digital watermark to obtain the location information;

identifying a map depicting a location corresponding to the location information; and

providing the map for access over a computer network.
