Abstract

L'invention concerne un système et un procédé de stockage et de lecture de chiffrement de fichier basé sur une empreinte digitale, et un terminal mobile. Le procédé, qui est appliqué au terminal mobile, comprend les étapes consistant à : créer un dossier de chiffrement selon une empreinte digitale de chiffrement d'entrée ; sélectionner un fichier à stocker, entrer une empreinte digitale sur un terminal mobile, et stocker le fichier dans un dossier chiffré correspondant lorsque l'empreinte digitale d'entrée est cohérente avec une condition de déverrouillage du dossier chiffré ; et le terminal mobile obtient l'entrée d'empreinte digitale par un utilisateur, met en correspondance l'empreinte digitale avec l'empreinte digitale du dossier chiffré, et ouvre le dossier chiffré correspondant pour lire le fichier lorsque les empreintes digitales sont mises en correspondance. Selon la présente invention, un utilisateur stocke un fichier par l'intermédiaire d'une empreinte digitale d'entrée, et stocke le fichier dans un dossier chiffré correspondant à une empreinte digitale chiffrée, de telle sorte que l'opération de stockage chiffrée est simple, rapide et pratique, sans opérations de sélection multiples, le saut de page est réduit, et l'expérience d'utilisation de l'utilisateur est améliorée avec une meilleure interactivité ; et l'utilisation pour l'utilisateur est pratique en effectuant une mise en correspondance par l'intermédiaire de l'empreinte digitale d'entrée et en affichant le dossier chiffré correspondant à l'empreinte digitale chiffrée pour une visualisation et une lecture de fichier, sans opérations de sélection secondaires.
