Device for intercepting and disrupting the hidden headsets

With the increased availability of technology and with the ability to miniaturize the electronic circuitry, more and more devices for cheating in exams are built. A cheating device is a complex system which allows a secret communication between the user and another person. However, a certain part of transmission is not encrypted in any form, and can be intercepted in a certain range. In this paper is presented one of the multiple ways to counter the devices used for cheating. The device is capable of intercepting and disrupting sounds transmitted through an inductive circuit and is hidden in a functional handheld Gameboy.
