Reverse Turing test

A reverse Turing test is a Turing test in which the objective or roles between computers and humans have been reversed. Conventionally, the Turing test is conceived as having a human judge and a computer subject which attempts to appear human. The intent of this conventional test is for the judge to attempt to distinguish which of these two situations is actually occurring. It is presumed that a human subject will always be judged human, and a computer is then said to "pass the Turing test" if it is also judged human. Critical to the concept is the parallel situation of a human judge and a human subject, who also attempts to appear human. Any of these roles may be changed to form a "reverse Turing test".
