CAPTCHA(Completely Automated Public Turing test to tell Computers and Humans Apart, 캡차)는 HIP(Human Interaction Proof) 기술의 일종으로, 어떠한 사용자가 실제 사람인지 컴퓨터 프로그램인지를 구별하기 위해 사용되는 방법이다. 사람은 구별할 수 있지만 컴퓨터는 구별하기 힘들게 의도적으로 비틀거나 덧칠한 그림을 주고 그 그림에 쓰여 있는 내용을 물어보는 방법이 자주 사용된다. 이것은 기존의 텍스트와 이미지를 일그러뜨린 형태로 변형한 후 인식 대상이 변형된 이미지로부터 기존 이미지를 도출해 낼 수 있는지를 확인하는 방식의 테스트이다. 컴퓨터 프로그램이 변형시킨 이미지는 사람이 쉽게 인식 할 수 있지만 컴퓨터 프로그램은 변형된 이미지를 인식하지 못하므로 테스트를 통과하지 못한다면 테스트 대상이 사람이 아님을 판정할 수 있다. 흔히 웹사이트 회원가입을 할 때 뜨는 자동가입방지 프로그램 같은 곳에 쓰인다.

CAPTCHA는 기기가 사람을 대상으로 하는 테스트이므로 사람에 가까운 기기를 대상으로 하는 테스트인 튜링 테스트(Turing test)에서 용어를 따와 리튜링 테스트(re-Turing test)라고 부르기도 한다.
