Abstract
Abstract Security documents which has multiple fields or areas each of which contains information that is perceptible in more than one way: One field can contain a visually perceptible image and a digital watermark that can be detected when the image is scanned and processed, another field can contain machine readable OCR text that can be read by both a human and by a programmed computer, and still another field can contain watermark data which can be correlated to the output of a fingerprint reader or apparatus which scans a user's iris. Documents are produced by begining with a template which defines the placements of elements on the document and the interrelationships between hidden and visual information on the document. The template specifies the placement of elements such as images, photographs, and text and it also specifies the interrelationship between information that is visually perceptible to a user of the document and information that is hidden by means of digital watermarks. Different hidden digital watermark data is included in multiple elements of the document. The watermarks in the different graphic elements of the document are correlated to each other and correlated to the visual material on the document. Thus, the document can not be forged by replacing one element (such as a picture) with a similar element from another document. In order to produce a document defined by a particular template, appropriate pictures, graphics and digital data are extracted from a data bank, and watermark data is embedded in the pictures and graphics as appropriate. The merged digital data is then sent to a printing engine and the final document is produced. An automatic validation system of the present invention reads multiple fields on the document, and it also automatically detects information about the user. The various information is correlated to validate the document.
