CA 2309623
A tamper-evident form for securely carrying information includes a scrambling pattern (4) which underlies the printed information such that the printed information cannot be read. Separation of the printed information and scrambling pattern, or other disabling of the scrambling pattern, is tamper- evident and renders the information readable. In preferred embodiments the information is printed on a lamina (6) which overlies the scrambling pattern (4). The information can be printed by conventional printers and no post- processing of the form is required to render the information secure.
La présente invention porte sur un support d'information inviolable, comprenant un système de brouillage (4) sous-jacent à l'information imprimée, de manière à empêcher la lecture de cette dernière. La séparation entre l'information imprimée et le système de brouillage, ou un autre moyen de neutraliser le système de brouillage, est inviolable, et permet de rendre l'information lisible. Dans les variantes préférées, l'information est imprimée sur une lamelle (6) sus-jacente au système de brouillage (4). Elle peut être imprimée par des imprimantes classiques, et aucun post-traitement du support n'est requis pour en assurer l'inviolabilité.
