Patent

CA 2272383

A cryptographic medium including embedded metallic particles. The particles provide a unique signature when the card is exposed to a radio frequency signal. The medium includes programming and storage capability, so that protocols for different types of transactions may be stored on the medium, along with personal information associated with the user of the token. The token may take the form of a plastic card, which includes an electronic module fabricated using a multi-chip module design and including the programming and storage capability. The design allows greater computing and storage capacity on the card. At least the electronic module is encapsulated in a plascon material, giving the overall card a more physically secure construction.

L'invention concerne un support cryptographique dans lequel sont noyées des particules métalliques. Les particules produisent une signature unique lorsque la carte est exposée à un signal de radiofréquence. Le support présente une capacité de programmation et de stockage de sorte que des protocoles pour différents types de transaction peuvent être mémorisés sur le support, ainsi que des informations personnelles associées à l'utilisateur du jeton. Le jeton peut prendre la forme d'une carte en plastique, laquelle contient un module électronique fabriqué selon une conception de module multipuce présentant la capacité de programmation et de stockage. Cette conception offre une plus grande capacité de calcul et de stockage sur la carte. Au moins le module électronique est encapsulé dans une matière plascon, donnant à la carte dans son ensemble une construction physiquement plus sécurisée.
