With such high stakes, several students take the risk of cheating on their exam. But the methods of cheating used are beyond conventional ones you may have seen, which is why test-administering authorities and students are always locked in battle, playing a constant game of cat and mouse. To one-up the students, authorities in the city of Luoyang are utilizing drones that fly over the students while they take the exam.
These drones aren’t just meant to monitor test-taking students. They also have the ability to pinpoint radio frequency. At this point, you’re probably wondering why detecting radio frequency matters in an examination hall. That’s because many Chinese students use tiny radio feeds to transmit and receive test information and answers. Students have improvised cheating techniques by using pinhole cameras located in their glasses to transmit images of the exam and in return, get solutions through a tiny earphone that is too small to spot by proctors. Besides glasses, students have placed pinhole cameras in pens and even water bottles.
The use of the drone creates a “dragnet”, which catches anyone using radio frequency. The drone can be flown 500 meters above the students and still pinpoint cheaters with amazing accuracy. With the introduction of this cutting-edge technique to bust cheating students, test-administering authorities can at least breathe a sigh of relief for now, until cheating students come up with something even more inventive in the future.
