Summary:Disclosed are a fake fingerprint detection method and device. According to one embodiment of the present invention, a fake fingerprint detection method includes the steps of: obtaining an enrollment fingerprint embedding vector corresponding to an enrollment fingerprint image; and generating a virtual enrollment fingerprint embedding vector, wherein the virtual enrollment fingerprint embedding vector has an environmental characteristic different from an environmental characteristic of the enrollment fingerprint image, and has a structural characteristic of the enrollment fingerprint image. 위조 지문 검출 방법 및 장치가 개시된다. 일 실시예에 따른 위조 지문 검출 방법은 등록 지문 영상에 대응하는 등록 지문 임베딩 벡터를 획득하는 단계 및 상기 등록 지문 영상의 구조적인 특성은 유지하면서, 상기 등록 지문 영상과 다른 환경 특성을 갖는 가상 등록 지문 임베딩 벡터를 생성하는 단계를 포함한다.
