Patent

CA 2677225

A system for generating secure documents includes a station for generating 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 element 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 indicating that the web page is genuine.

L'invention concerne un système pour générer des documents sécurisés comprenant une station pour générer un document uni et un générateur d'image de sécurité générant une image de sécurité. L'image de sécurité est ensuite incorporée dans le document uni. Chaque image de sécurité est constituée d'une pluralité d'éléments sécurisés, chaque élément sécurisé étant défini par deux ensembles de lignes parallèles. Chaque élément sécurisé définit un caractère alphanumérique ou une autre image unique visible uniquement dans certaines conditions, à savoir, lorsqu'elle est inspectée par l'intermédiaire d'un visualiseur. La technique peut également être utilisée pour fournir des images de sécurité sur une page Web comme moyen d'indiquer que la page Web est authentique.
