L'invention concerne un procédé de communication d'image de sécurité, un dispositif côté émission, un dispositif côté réception, un dispositif à système de communication, un programme de traitement de communication, ainsi qu'un support d'enregistrement contenant ce programme, lequel permet de déformer une image originale de sorte que cette image ne puisse être lue que par un récepteur particulier. Le dispositif à système de communication d'image de sécurité comprend une voie de communication, un dispositif côté émission d'image de sécurité destiné à créer une image de sécurité par déformation d'une image originale et à émettre l'image de sécurité, ainsi qu'un dispositif côté réception d'image de sécurité destiné à créer une image originale restaurée à partir de l'image de sécurité produite en sortie et reçue par la voie de communication. Le dispositif côté émission d'image de sécurité se caractérise en ce qu'il comprend une unité de lecture d'image originale, une unité d'établissement de mot de passe, ainsi qu'une unité de traitement de déformation d'image. Le dispositif côté réception d'image de sécurité se caractérise en ce qu'il comprend une unité de lecture d'image de sécurité, une unité d'entrée de mot de passe, ainsi qu'une unité de traitement de déformation inverse d'image.
