Patent

CA 2494592

A security document, such as a banknote or a cheque, is provided with a perforation pattern (5) having holes (5a, 5b) with elongate cross section. When viewing the perforation pattern (5) from a direction that is non- perpendicular to the surface of the document, different holes will have different optical transmission, which can be verified by eye or electronically. Perforation patterns (5) of this type are hard to forge and easy to verify.

L'invention concerne un document sécurisé, tel qu'un billet de banque ou un chèque, comprenant un motif perforé (5) comportant des trous (5a, 5b) avec une section allongée. Lorsque l'on observe le motif perforé (5) dans un sens non perpendiculaire à la surface du document, des trous différents produisent des effets optiques différents pouvant être contrôlés à l'oeil nu ou par voie électronique. Les motifs perforés (5) de ce type sont difficiles à falsifier et faciles à contrôler.
