Zusammenfassung:	The present invention provides an apparatus for detecting forged biometric information, which includes an image input unit for receiving a biometric image, a skin color amplifying unit for amplifying a brightness component of a skin color region from the biometric image which is received, a physiological signal extracting unit for extracting a physiological signal from the amplified skin color region, a physiological signal analyzing unit for amplifying the extracted physiological signal and analyzing deviation information of an inflection point, and a forged information determining unit for detecting the forged biometric information from the analyzed physiological signal. Therefore, the present invention can determine whether biometric information which a user currently attempts to recognize is real physiological information or forged biometric information by analyzing the physiological signal acquired through the amplification of a skin color. 본 발명의 생체 영상을 입력받는 영상 입력부, 입력받은 생체 영상에서 피부색 영역의 밝기 성분을 증폭하는 피부색 증폭부, 증폭된 피부색 영역에서 생리 신호를 추출하는 생리 신호 추출부, 추출된 생리 신호의 증폭 및 변곡점의 편차 정보를 분석하는 생리 신호 분석부, 분석한 생리 신호로부터 위조 바이오 정보를 검출하는 위조 정보 판별부를 포함하는 위조 바이오 정보 검출 장치를 제공한다. 따라서, 본 발명은 피부색 증폭을 통해 획득한 생리 신호를 분석하여 현재 인식을 시도하는 바이오 정보가 실제 생체 정보인지 위조된 생체 정보인지를 판별할 수 있는 효과가 있다.
