Patent

CA 2697075

A method is disclosed, which includes receiving a message including an account identifier and a first verification value. The method uses the account identifier to select a dynamic verification value process from at least two dynamic verification value processes. Then, using the selected dynamic verification value process, a second verification value is determined. Next, the method determines if the first verification value and the second verification value match or are within an expected range.

L'invention concerne un procédé qui consiste à recevoir un message comprenant un identifiant de compte et une première valeur de vérification. Le procédé utilise l'identifiant de compte pour sélectionner un processus de valeur de vérification dynamique à partir d'au moins deux processus de valeur de vérification dynamique. Ensuite, en utilisant le processus de valeur de vérification dynamique sélectionné, une deuxième valeur de vérification est déterminée. Après, le procédé détermine si la première valeur de vérification et la deuxième valeur de vérification correspondent ou se situent dans une plage prévue.
