Summary:Provided are a device and protection method for protecting content by using biometric information. A content protection method according to an embodiment of the present disclosure may comprise the steps of: displaying identification information of encoded content; receiving a user input of selecting the encoded content; obtaining image information of a body part of a user by controlling a sensor, in response to receiving the user input of selecting the encoded content; calculating feature information of the body part of the user from the obtained image information; reconstructing an encryption key on the basis of hint information stored in response to the encoded content and the calculated feature information of the user; decoding the encoded content on the basis of the reconstructed encryption key; and displaying the encoded content as the encoded content is decoded. L'invention concerne un dispositif et un procédé de protection destiné à protéger un contenu à l'aide d'informations biométriques. Un procédé de protection de contenu selon un mode de réalisation de la présente invention peut comprendre les étapes consistant à : afficher des informations d'identification de contenu codé ; recevoir une entrée d'utilisateur consistant à sélectionner le contenu codé ; obtenir des informations d'image d'une partie du corps d'un utilisateur en commandant un capteur, en réponse à la réception de l'entrée d'utilisateur consistant à sélectionner le contenu codé ; calculer des informations de caractéristique de la partie du corps de l'utilisateur à partir des informations d'image obtenues ; reconstruire une clé de chiffrement sur la base d'informations d'indication stockées en réponse au contenu codé et des informations de caractéristique calculées de l'utilisateur ; décoder le contenu codé sur la base de la clé de chiffrement reconstruite ; et afficher le contenu codé à mesure que le contenu codé est décodé. 생체 정보를 이용하여 컨텐트를 보호하는 디바이스는 및 보호 방법이 제공된다. 본 개시의 일 실시예에 따른 컨텐트 보호 방법은, 암호화된 컨텐트의 식별 정보를 디스플레이하는 단계, 암호화된 컨텐트를 선택하는 사용자 입력을 수신하는 단계, 암호화된 컨텐트를 선택하는 사용자 입력을 수신함에 따라, 센서를 제어하여 사용자의 신체 부위의 이미지 정보를 획득하는 단계, 획득된 이미지 정보로부터 사용자의 신체 부위의 특징 정보를 산출하는 단계, 산출된 사용자의 특징 정보 및 암호화된 컨텐트에 대응하여 저장된 힌트 정보에 기초하여 암호화 키를 복원하는 단계, 복원된 암호화 키에 기초하여 암호화된 컨텐트를 복호화하는 단계 및 암호화된 컨텐트가 복호화 됨에 따라, 암호화된 컨텐트를 디스플레이하는 단계를 포함할 수 있다.
