In a darkroom, an investigator at the University and College Council examines the authenticity of a certificate for an engineering degree from the University of Damascus - the university that stands out with the most suspected cases of cheating.

In the video above, the investigator, who for security reasons wishes to remain anonymous, talks about deviations that may be signs of forgery.

- Many counterfeits are really sophisticated and can be difficult to detect, it is important to know what you are looking for, says Cecilia Ulfsdotter, head of unit at the University and College Council.
