    摘要: Digital watermarking technology is used in an image management system. Images are uniquely identified by digital watermarking. The images are stored so as to be indexed according to unique identifiers. In one embodiment, related images are linked together by a unique watermark identifier. The unique watermark identifier is also used to manage metadata, and provide forensic tracking. Watermark identifiers can be used to carry or access security clearance information associated with an image or other media. Other embodiments are provided as well.

    摘要: A map depicts a plurality of different locations. Steganographic encoding is embebbed in first and second map areas. Steganographic encoding in each area conveys an identifier that is associated with its respective map area. Different encoded identifiers are used to link to information pertaining various different locations depicted in the map.

    摘要: A geographic information system digitally watermarks by modifying pixels from a source image with additional spatial and non-spatial information for a destination image. When an image is digitally watermarked, the pixels of the image are modified to include an embedded redundant pattern that is imperceptible to viewers of the image. The redundant pattern of changes from the “digital watermark” can be converted back into a payload containing meaningful data, and in some examples into unique identifiers. The payload is arranged to link the image to additional information such as copyright information, geospatial data, and related applications and services. Since the payload is embedded within the pixels of the image, no additional storage space is required, and the information is arranged to survive various image manipulations that might be employed by a user such as: translation of image formats, rotation, scaling, cropping, printing and scanning, and many other image processes.

    摘要: The ability to remove a watermark from an encoded image opens the possibility of various novel applications. Several such applications are detailed. One employs a reversible watermark in conjunction with a second (robust) watermark. In this arrangement, the payload of the reversible watermark conveys information about the robust watermark (e.g., encoding parameters, or an error signal), permitting removal of the robust watermark from an uncorrupted encoded image. By such arrangements, the encoded image can be fully restored to its pristine, unencoded state even if several different watermarks have been applied.

    摘要: A variety of systems responsive to watermarked documents are detailed. In one, watermarking is employed to facilitate secure online transactions. In another, a system for exchanging data is provided. One system includes a user terminal and a central site. The user terminal includes a watermark reader, and a capture device to capture an image of a watermarked document. The central site includes a database of image hashes. The user terminal communicates with the central site. The watermark reader reads a watermark and computes a hash of a captured image, and passes the hash to the central site for comparison with the database of image hashes.
