摘要： Maps and/or signs are embedded with plural-bit data in the form of digital watermarks. In one implementation, an apparatus is provided to read two or more digital watermarks embedded within a map. Each of the two or more digital watermarks includes location information for a respective map location. The two or more digital watermarks are embedded through alterations to data representing the map; the alterations are generally imperceptible to a human observer of the map. The apparatus includes: a global positioning system receiver to determine a physical location of said apparatus; an input to receive data corresponding to at least a portion of the respective map area; a processor or electronic processing circuitry to extract the location information from the input data and to correlate the physical location with the extracted location information; and an output to output an indication of a relative correlation between the physical location and watermark location information. Other implementations are provided and claimed as well.

摘要： The present invention relates to detecting steganographically hiding images and information. In a preferred embodiment, an image is hidden within a media signal. The media preferably includes a cyan (C) color plane, a magenta (M) color plane, a yellow (Y) color plane and a black (K) color plane. In an alternative embodiment, the media includes a spot color. The image is converted into a black color channel image and is then applied to the media's K channel. The black channel image is inverted and the inverted image is applied to the media's CMY (or spot) color planes. For detection, the embedded media is illuminated with infrared light, which emphasizes the black color plane. An input device captures a digital image of the illuminated media. The image is detected or displayed based on the emphasized black plane.
