본 논문에서는 압축도메인 특징을 이용한 오디오 핑거프린팅 방법을 제안하였다. 압축도메인을 이용함으로써 계산량과 시간을 크게 줄일 수 있는 장점이 있다. 특히 오디오 압축에 널리 쓰이고 있는 MDCT 도메인을 이용하였으며, MDCT 도메인을 부밴드로 나누고 대표적인 모멘트 특징인 에너지, 무게중심, 평탄도로 부터 각각 핑거프린트를 얻었다. 추출된 특징을 차분 필터링하고 부호를 취하여 이진 핑거프린트를 얻었다. 실험을 통해서 고려한 MDCT 도메인 특징들로부터 얻은 핑거프 린트들의 인식 성능을 비교하였다. 수 천곡 규모의 오디오에 대해서 다양한 변환에 대한 인식 성능을 고려하였으며, 실험 결과 부밴드 에너지가 가장 우수한 핑거프린팅 성능을 보였다.
