IMPROVED METHOD AND SYSTEM FOR PRODUCING DOCUMENTS, WEBSITES, AND THE LIKE HAVING SECURITY FEATURES

摘要

A system for generating secure documents includes a station for generatin g a plain document and a security image generator that generates a security image. The security image is then incorporated into the plain document. Each security image consists of a plurality of secure elements, each secure elem ent being defined by two sets of parallel lines. Each secure element defines an alphanumeric character or other unique image that is visible only under certain conditions, i.e., when inspected through a viewer. The technique can also be used to provide security images on a web page as a means of indicat ing that the web page is genuine.
