Abstract (en)
The confidential information being composed of symbols belonging to a first series (3), a second series of symbols (4) is defined, the first and the second series of symbols are displayed in a random relative position, and this matching is used to input the confidential information so that a third party observing the input operations cannot determine the confidential information. The invention also relates to the terminal associated with this method. <IMAGE>
Abstract (fr)
L'information confidentielle étant composée de signes appartenant à une première série (3), on définit une seconde série de signes (4), on affiche la première et la seconde séries de signes selon une position relative aléatoire, et on utilise cette mise en correspondance pour saisir l'information confidentielle de sorte qu'un tiers qui observe les opérations de saisie ne peut pas déterminer l'information confidentielle. L'invention concerne aussi le terminal associé à ce procédé. <IMAGE>
