Abstract

L'invention concerne un procédé pour transporter des informations cachées dans une image d'affichage, lequel procédé consiste : à insérer des informations cachées préétablies qui ne peuvent pas être reconnues par les yeux humains dans une image d'affichage, de façon à former une image d'affichage synthétisée; et à acquérir les informations cachées insérées lorsque l'image d'affichage synthétisée est balayée par l'intermédiaire d'une extrémité de balayage, et à analyser et à acquérir des informations numériques qui correspondent aux informations cachées. L'invention concerne un terminal et un système d'affichage pour transporter des informations cachées dans une image d'affichage. Le terminal et le système d'affichage font de telle sorte que des informations requises sont publiées à un utilisateur par l'intermédiaire d'une image d'affichage sans affecter la visualisation et l'exploitation de l'image d'affichage par l'utilisateur.
