摘要: The present invention provides methods and systems for authenticating identification documents. We also teach an identification document including two or more digital watermarks. The watermarks correspond with each other or with indicia carried by the identification document. The correspondence can be verified to determine authenticity. We also provide digital watermark detection methods and systems to identify the different watermarks through embedded orientation components. We then focus watermark message-decoding efforts on areas identified as likely including watermark orientation components. In one implementation we provide a watermark detection trigger to identify so-called legacy documents. The trigger may indicate the presence or expected absence of a digital watermark. In other implementations we provide a versatile document authenticator to toggle between watermarking and non-watermarking authentication processes depending on a detection trigger.

摘要: 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.

摘要: 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.

摘要: 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.
