Abstract

La présente invention concerne un procédé empêchant de regarder un écran sans autorisation destiné à un terminal mobile, le terminal mobile et un support d'informations. Le procédé comprend les étapes consistant : à appeler une caméra avant au moyen d'un terminal mobile pour acquérir des images de façon à obtenir une image courante lorsqu'un écran est à l'état éclairé ; à extraire de l'image courante des informations de caractéristiques faciales qui remplissent une condition prédéfinie ; à déterminer le nombre de visages dans l'image courante selon les informations de caractéristiques faciales ; et à émettre à destination de l'utilisateur des informations d'invite empêchant de regarder l'écran sans autorisation lorsque le nombre de visages dépasse un nombre prédéfini. Puisqu'une image est acquise par une caméra avant et que le nombre de visages dans l'image est déterminé en fonction de l'image acquise, il est possible de déterminer l'existence éventuelle d'un risque que l'écran soit regardé sans autorisation quand le nombre de visages dépasse un nombre prédéfini. En outre, des informations d'invite empêchant de regarder l'écran sans autorisation sont émises à destination de l'utilisateur pour lui rappeler de veiller à la confidentialité, ce qui empêche efficacement des étrangers de regarder l'écran sans autorisation, et évite la fuite d'informations privées.
