'FADTCHA'(FAce Detection Turing test to tell Computers and Humans Apart) is a type of challenge-response test to determine whether the response is generated by a computer. The test involves asking a testee to find* a face in a presented image and draw a square region of the face. If one correctly finds a face, it can be presumed that it is a computer, otherwise it will be regarded as a non-computer.

This project is inspired by CAPTCHA which is a test to tell whether its user is a human or a computer. CAPTCHA asks a user to type text from a distorted image. This is easy for humans but difficult for computers. It sorts out computers by having them complete a task which only humans can.

'FADTCHA' presumes a reverse situation. It requires a user to find a face in an image, which is visible only to computers. This test can pick out non-computers.

*The finding is to be conducted with OpenCV face detection.
