    摘要: Digital watermark methods for encoding auxiliary data into a host signal are used to authenticate physical and electronic objects. In one implementation, an identification document includes electronic circuitry. The electronic circuitry includes an image of an authorized bearer of the identification document. The image includes first digital watermarking having a plural-bit identifier. In some cases, the identification document includes a printed image of the authorized bearer of the identification document. The printed image includes second digital watermarking therein. The first digital watermarking and the second digital watermarking can be cross-correlated for authentication of the identification document.

    摘要: Maps and signs are embedded with plural-bit data in the form of digital watermarks. In one embodiment, the plural-bit data includes location information with respect to a map. A handheld reading device extracts the location information from the map. The reading device then compares the location information with a physical location of the device. Feedback is provided to help a device user to correlate the map location with the physical location. In another embodiment, signs are watermarked to provide navigational and informational aids. The watermarks may include unique identifiers, which allow database lookup of related information.

    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.
