Abstract

L'authentification par numéro d'identification personnel (PIN) pour les cartes bancaires de débit et autres cartes est de plus en plus importante car les ventes au détail et autres transactions utilisent de plus en plus l'authentification par PIN au lieu de l'authentification par signature. Il est fréquent que les terminaux points de vente actuels qui exigent une authentification par PIN utilisent des claviers facilement visibles pour d'autres personnes se trouvant à proximité de ces terminaux. Par conséquent, il est possible de subtiliser le numéro d'identification personnel d'un client en le regardant saisir ce numéro sur le clavier standard d'un terminal point de vente. Selon un mode de réalisation de l'invention, un terminal personnel sécurisé muni d'un clavier virtuel permet de résoudre ce problème car il présente un clavier aléatoire uniquement au client et il reçoit en même temps une saisie sur un clavier qui est vierge pour les personnes se trouvant à proximité.
