Patent

CA 2403234

The invention provides a computer implemented system and method for assuring security and validity of pseudo randomly numbered authorization codes, typically printed on certificates or stored in machine readable memory on user's cards, including a first algorithmic means on a first computer for generating an authorization code in response to a request, and a second algorithmic means on a second computer for determining if a code provided by a user is an authorization code that would be generated by said first algorithmic means. The transmission of the second algorithmic means to the second computer obviates the requirement to transmit actual generated codes from the computer providing the authorization code to the computer determining if the code presented by a user is an authorized code.

L'invention concerne un système et un procédé informatisés pour assurer la sécurité et la validité de codes d'autorisation numérotés de manière pseudo-aléatoire, d'ordinaire imprimés sur des certificats ou stockés dans une mémoire lisible par machine sur des cartes d'utilisateurs, qui consistent notamment en un premier moyen algorithmique sur un premier ordinateur permettant de produire un code d'autorisation en réponse à une demande, et un second moyen algorithmique sur un second ordinateur pour déterminer si l'utilisateur a bien fourni un code d'autorisation produit par le premier moyen algorithmique. L'émission du second moyen algorithmique vers le second ordinateur supprime l'exigence d'émettre des codes réels produits à partir de l'ordinateur fournissant le code d'autorisation vers l'ordinateur qui détermine si l'utilisateur a bien présenté un code autorisé.
