    摘要: An improved method of watermarking picture identification documents (IDs) such as passports, driver's licenses, identification cards and the like which combines biometric information with digital watermarking to provide an improved secure picture ID document and authentication of same. A facial image—that is part of the identification document—is processed such that particular facial features are extracted from the overall facial image. The extracted features are used to generate a watermark key that is subsequently used to embed a unique watermark into the facial image or other location on the identification document.
