India’s northernmost states of Chamu and Kashmir are installing 800 cell phone jammer in testing centers across the country to combat fraud. A new prominent case shows the problem: Wasim Ahmed, a student at the Nawab Shah College of Engineering in India, was accused of cheating. He puts the smartphone in his underwear, the microphone in his shirt, and the Bluetooth headset in his ears. He whispered the questions for the waiter. Behaviors like Ahmad happen frequently all over the world, but the details may vary.
Earlier this month, four students cheated in the entrance exam, and a scandal occurred in the Medical School of Reims University, Thailand. Two of them wore glasses with built-in cameras, and three wore smart watches. The glasses took pictures of the exam. During the break, the examinee handed the glasses to the person holding the photo, and then sent the photo to allies in the designated “command center” located elsewhere. The accomplice researched these questions and sent the answers back to the candidate, who can see the text message on the smart watch. The good news is that they were caught. The problem of cheating on the Internet with connected devices is very serious. Iraq actually shut down most of the country’s Internet to prevent sixth-grade students from cheating.
Some devices will interfere with the phone signal, and in fact will pretend to be a base station when not interfering. The problem is that it disables emergency calls. In theory, you can implement some functions that put the phone in a place where calls are not allowed (because the operator always knows where the phone is), thereby putting the phone in “mode”. But no one recommends it as a product or standard, although it is not particularly difficult. Maybe it’s because the owner of the movie theater, the restaurant owner has to pay for it.
