Abstract

La présente invention se réfère à un dispositif d’entrée de chiffrage à l’épreuve des regards indiscrets qui se caractérise par le fait que la touche (1) sur le clavier est constituée d’un corps transparent ou d’une lentille convexe (b) et du panneau extérieur non transparent fixés ensemble. Le fond du panneau extérieur non transparent se trouve en contact par ressort avec le microrupteur ou l’interrupteur à couche mince (3) qui est positionné en correspondance à la tige de la touche sur le dispositif de commande (2) du fond. Un support d’écran à caractères (5) monté sur la carte mère se trouve sous le pore d’ouverture du dispositif de commande correspondant au corps transparent ou à la lentille convexe. Un circuit d’entrée de chiffrage est formé en connectant la sortie du microrupteur ou de l’interrupteur à couche mince (3) composant la matrice de touches et l’entrée de l’unité centrale sur la carte mère. Cette structure permet d'empêcher que l’entrée de chiffrage soit observée de manière indiscrète ou dérobée. La présente invention adopte un procédé di disposition aléatoire du bit de caractères 0-9 attribué à la touche avec un ordre variable afin de réaliser le dispositif d’entrée de chiffrage à l’épreuve des regards indiscrets.
