Abstract

L'invention concerne un procédé de cryptage/décryptage d'un document électronique basé sur l'identification d'un visage humain. Le procédé consiste à acquérir des données vidéo de visage humain, et à comparer les données vidéo du visage humain acquises durant le décryptage avec les données vidéo du visage humain acquises durant le cryptage, en vue d'obtenir la similitude, de façon à crypter/décrypter le document électronique de manière simple et rapide et à l'obtenir facilement. La particularité unique de l'information caractéristique du visage humain se traduit par une grande sécurité, une grande fiabilité et une grande applicabilité.
