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.
