Abstract: The present invention relates generally to fingerprinting (i.e., human fingerprints). More specifically the present invention relates to explicitly embedding so-called fingerprint minutiae locations in an identification document via digital watermarking. A relative mapping of the minutiae locations can be transformed, scrambled and combined with a watermark orientation component, and then embedded in a photograph or artwork. The embedded photograph or artwork is printed on, e.g., an identification document. Another aspect of the invention is a matching method used to match a representation of a set of control minutiae locations with a representation of a set of sample minutiae locations.

Abstract: The present invention provides steganographic and digital watermarking methods and apparatus. In a first implementation, we provide methods and apparatus for steganographically conveying data in a facial image by subtly altering facial features relative to statistical norms. In a second implementation, we convey data through different patterns of a diffraction grating. In a third implementation, we convey a digital watermark orientation component by projecting the orientation component onto an object to be captured. In the case of blue-screen technology, we incorporate an orientation component into a blue-screen itself. This provides great convenience for digital animators when overlay graphics and animation. In a forth implementation, we provide an identification document including an electronic memory chip. The chip includes an image of a bearer of the identification document. The image is digitally watermarked to include information (e.g., a chip serial number or document number) that is carried by the identification document. Thus, the electronic memory chip is tied to the document.

Abstract: This disclosure describes apparatus and systems for encoding and decoding signals from a host signal such as audio, video or imagery. One claim recites an apparatus comprising: electronic memory for storing a media signal representing audio or video; and an electronic processor. The electronic processor is programmed for: extracting data representing at least some features of the media signal; using the extracted data as a key to select coefficients in a transform domain, the coefficients representing the media signal; and modifying selected coefficients to hide a steganographic signal in the media signal. Of course, other claims and combinations are provided as well.

Abstract: The ability to remove a watermark from encoded content (e.g., an 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.

Abstract: The ability to remove a watermark from an encoded image by reversible watermarking opens the possibility of various novel applications. Several such applications are detailed. One permits different classes of consumers to gain access to different versions of an image. A pristine image is intentionally degraded in some fashion, and distributed to consumers. By reference to one or more watermarks in the degraded image, some or all of the degradation can be removed, or transformed to a less-objectionable state. Through such arrangements, image consumers with different needs can gain access to versions of the image having differing qualities.

Abstract: The present invention provides steganographic embedding and detecting techniques, along with related apparatus. One claim recites a signal detector including: an input and an analyzer. The input obtains media including a signal hidden therein. The signal including plural-bit data, the signal being hidden in the media through an arrangement of message objects. The arrangement is facilitated—at least in part—through thresholding of a steganographic signal representing or carrying the plural-bit data. The analyzer analyzes the media to obtain the plural-bit data. Of course, other combinations are provided and claimed as well.
