Abstract
(EN) An apparatus for protecting and recovering a system file comprises: a system file setting unit which sets a system file within an operating system program of a computing apparatus; a hash value calculation unit which calculates a hash value for the set system file on a preset cycle, and stores the calculated hash value in a storage unit; and a file backup unit which encodes the system file corresponding to the calculated hash value, and stores the encoded system file in the storage unit.
(FR) L'invention concerne un appareil pour protéger et récupérer un fichier de système, lequel appareil comprend : une unité de configuration de fichier de système qui configure un fichier de système à l'intérieur d'un programme de système d'exploitation d'un appareil informatique ; une unité de calcul de valeur de hachage qui calcule une valeur de hachage pour le fichier de système configuré sur un cycle préconfiguré, et stocke la valeur de hachage calculée dans une unité de stockage ; et une unité de sauvegarde de fichier qui code le fichier de système correspondant à la valeur de hachage calculée, et stocke le fichier de système codé dans l'unité de stockage.
(KO) 시스템 파일 보호 및 복구 장치는 컴퓨팅 장치의 운영체제 프로그램 내 시스템 파일을 설정하는 시스템 파일 설정부와, 설정된 시스템 파일에 대해 기설정된 주기로 해쉬값을 산출하고, 산출된 해쉬값을 저장부에 저장하는 해쉬값 산출부와, 상기 산출된 해쉬값에 대응하는 시스템 파일을 암호화하여 상기 저장부에 저장하는 파일 백업부를 포함한다.
