Advanced Instruments Help the College Entrance Examination, Ensuring the Continued Prosperity of the Path to National Rejuvenation Through Science and Education

The National College Entrance Examination (Gaokao) is seen by university students as akin to "thousands of troops crossing a single-plank bridge." Those with genuine talent and ability are naturally fearless, but those who are merely pretending to be capable inevitably try to cheat and take shortcuts. Cheating in exams has existed since ancient times and has been difficult to eradicate. With the advancement of technology, the tools used for cheating have become increasingly sophisticated, truly a case of "each displaying their own unique abilities." However, as the saying goes, "the devil is one foot tall, but the righteous are ten feet tall," various instruments such as metal detectors, radio signal jammers, and ID verification devices are now widely used in examination rooms to strictly prevent various forms of cheating. Let's take a look at how these various instruments assist in the Gaokao and break down those cheating "gates."

GPS Positioning and Monitoring of Exam Papers Throughout the Entrance Examination

According to the Ministry of Education, the exam papers have been distributed to districts and counties, and the monitoring equipment, cheating prevention equipment, and exam paper security equipment in standardized examination rooms across the country are all in place. In 2017, 26 provinces across China will use unified exam questions. The entire process, from printing to the examination area, will be monitored by GPS and mobile video surveillance. The National Education Examinations Authority will use "electronic eyes" to conduct real-time electronic monitoring of all exam paper storage rooms nationwide.

Metal detectors filter out various communication devices.

Currently, invigilators across the country are equipped with handheld metal detectors to strengthen security checks at exam venues. Candidates are required to cooperate with invigilators during security checks upon entry. The metal detector used in the National College Entrance Examination (Gaokao) is a long, flat black rod. Invigilators hold the detector and run it around the candidate's back, sides, and other areas where items are easily concealed. If a metal object is found, even a small metal button, the detector will sound an alarm, and the candidate must present the object. The metal detector ensures that candidates are not carrying mobile phones or other communication devices.

ID verification devices, fingerprint recognition, and facial recognition provide triple protection against proxy test-taking.

Video surveillance in exam rooms makes identity verification a crucial function. In recent years, ID verification devices have become the first choice for verifying the authenticity of ID cards in the examination industry. When college entrance examination candidates enter the examination room, they must hand over their admission ticket and ID card to the invigilator for inspection. Simultaneously, an ID card reader is used to verify the authenticity of the candidate's second-generation ID card. This involves automatically reading the information on the document locally and automatically detecting and capturing the candidate's face. The features of the photo on the document are compared with the real-time facial features. Only after the comparison is successful can the candidate enter the examination room to participate in the test. Upon entry, all candidates' fingerprints are verified using a fingerprint reader. Only if the fingerprints match the information collected during registration are candidates allowed to enter the examination room. These methods scientifically and effectively identify genuine and fake test takers, leaving no room for impersonation.

Mobile phone signal jammers and hidden earphone detectors strictly prevent cheating.

Mobile phone signal jammers scan from the low end to the high end of the forward channel at a certain speed during operation. This scanning speed can create scrambled interference in the mobile phone's received message signal, preventing the mobile phone from detecting normal data transmitted from the base station and thus preventing the mobile phone from establishing a connection with the base station. The mobile phone exhibits phenomena such as searching for a network, no signal, and no service system. Meanwhile, to prevent the use of wireless hidden earpieces to receive answers transmitted from outside, wireless hidden earpiece detectors will be used in the college entrance examination rooms to locate the source of cheating. As soon as a hidden earpiece is detected emitting a signal in the examination room, the detector will immediately emit an alarm sound, thus further ensuring the fairness and impartiality of the examination. This year's college entrance examination is the "strictest in history," and examination authorities across the country have installed high-powered mobile phone signal jammers to block mobile communication signals, walkie-talkie signals, and wireless transmission signals.

Radio monitoring vehicles are on the move to catch "slippery fish"

To combat high-tech cheating, anti-cheating measures are constantly being upgraded from "human defense" to "technological defense." Attentive candidates will notice that many school gates have radio monitoring vehicles parked outside, with staff using professional wireless equipment to search for suspicious signals. Once a suspicious signal is detected, it will be immediately suppressed point-to-point.

In addition, to increase the prevention and control of violations and cheating, other high-tech products are also being used in the examination rooms. The college entrance examination is a major life event, and all sectors of society are actively cooperating with it. The use of high-tech equipment can prevent cheating and ensure the fairness of the examination. All candidates are urged to abide by the examination rules and take the exam honestly. At the same time, candidates should be aware of their own safety and take precautions to prevent others from copying their answers. Furthermore, when filling in the exam paper code, candidates must fill it in personally and ensure it matches the code on the first page of their answer sheet; otherwise, the exam paper will be considered invalid.
