Cheating means nothing more than plagiarism, which is mainly divided into four categories: carrying information secretly, peeping at other people's test papers, communicating with the outside world, and taking the test with fake identities. Among them, peeping at other people's test papers is cheating on the spot, which requires invigilators and on-site monitoring to make judgments. Carrying data secretly is divided into carrying paper data, microform data, electronic storage and display equipment, etc. The current high-tech cheating methods are mainly reflected in external communication, and also include some storage devices without communication functions. One of the hot spots in the early stage of the college entrance examination this year is that Apple's Apple Watch will not be allowed to be brought into the examination room. In fact, there are many such electronic devices, such as electronic dictionaries, PDAs, mobile phones, etc., due to the digitization of documents, people can use extremely small These electronic devices can also be disguised as pens, erasers and other stationery styles, but usually these devices can be detected by Inexpensive Cell Phone Jammer . Of course, there are exceptions. For example, non-electronic devices containing a large amount of information can also be made using microprinting technology and plastic mechanical devices, which requires the eyes of inspectors. With the popularization of wireless communication technology, the main cheating methods at present are also communication tools inside and outside the examination room. On the one hand, mobile phones and other devices with communication functions are prohibited from entering the examination room, and on the other hand, wireless signal jammers and signal detection tools are used for real-time monitoring. Surveillance, UAV is a typical example that appeared this year, because it can be operated remotely and has a wider coverage, it can achieve comprehensive monitoring without dead ends. It is no exaggeration to call it the ultimate weapon. cell phone jammer Get rid of the phone. You can do more work by deliberately focusing instead of letting yourself jump out of the task and think about things.
In the process of cheating, one-way communication is often used with off-site communication. Voice and text information are received through hidden or disguised wireless devices, and sent through mobile phones, walkie-talkies, or car radios. The first prevention method is through To detect in advance, one is to shield the signal interference and find out the source of the signal. In addition, the use of multiple exams is also a means to prevent such cheating methods. With the concealment of cheating tools, wireless interference and shielding have become the main means. Invisible earphones have become a popular tool for cheating in the college entrance examination in recent years due to their concealment. Some products are even implanted in the body and require surgery to remove them. In addition, there are oral earphones, which will be swallowed and destroyed after being discovered. The cheating eraser adopts the method of accepting text. Through the eraser camouflage, the built-in receiver can display digital or text information. The smart watches and smart glasses that cheated in the college entrance examination actually appeared far before the smart watches in the field of consumer electronics, disguised as ordinary items, but with the function of receiving information. Diverse. Therefore, this college entrance examination also prohibits the admission of devices including smart glasses, watches, and bracelets. Anti-cheating tools mainly include detectors, Inexpensive Cell Phone Jammer , signal transmission tracking devices, etc. In fact, the principle is to prevent signal transmission. However, in reality, not all test centers in all regions have complete equipment. For example, some test centers cannot detect hidden devices. Or some frequency bands of 4G are not shielded and there are still signals, and some transmission frequencies of wireless devices are not within the shielding range.
