CA 2528451

A Chip Authentication Program based on 3-D Secure protocols is provided for authenticating customers' (180) on-line transactions. An issuer, who may be a payment card issuer, operates Access Control and Authentication Request Servers (120) for authenticating transactions by individual customers (180) who are identified by their personal EMV-complaint smart cards (170). An authentication token is generated at the point of interaction (POI) for each transaction based on information from the customer's smart card (170) and transaction specific information sent directly by the issuer to populate a web page at the POI. Authentication tokens generated at the POI are evaluated by the Authentication Request Server (120) to authenticate individual customer and/or card presence at the transaction POI. Authentication values are transported on-line in designated Universal Cardholder Authentication Fields consistent with 3-D Secure protocols.

L'invention concerne un programme d'authentification de puce fondé sur des protocoles sécurisés 3-D qui permet d'authentifier des clients de transactions en ligne. Un émetteur, éventuellement un émetteur de cartes de paiement, gère des serveurs de commande d'accès et de demande d'authentification qui permettent d'authentifier des transactions effectuées par des clients identifiés par leurs cartes à mémoire personnelles de réclamations EMV. Un jeton d'authentification est créé au point d'interaction pour chaque transaction en fonction des informations provenant de la carte à mémoire du client et des informations propres à la transaction envoyées directement par l'émetteur pour alimenter une page web au point d'interaction. Les jetons d'authentification générés aux points d'interaction sont évalués par le serveur de demande d'authentification pour authentifier le client et/ou la présence de la carte au point d'interaction de la transaction. Des valeurs d'authentification sont transportées en ligne dans des champs d'authentification de titulaires de cartes universels désignés conformes à des protocoles sécurisés 3-D.
