"Technical content" college entrance examination fraud case equipment is placed in the ear canal

"2 1 off-site personnel, 9 cheating students. The cheater placed a miniature receiver the size of a soybean near the cochlea in the ear canal and received the answer by radio. " On June 17, news came from Jinhua City, Zhejiang Province that a large-scale college entrance examination (Q bar) fraud occurred in Yongkang No.1 Middle School and No.2 Middle School affiliated to Jinhua. "The scale is unprecedented and the means are strange." The informant said.

The Information Industry Department of Zhejiang Province confirmed that on the morning of June 7 and the afternoon of June 8, Yongkang, a subordinate radio management office of Jinhua City, seized three gang cases of cheating in the college entrance examination by using radio equipment and technology.

The case was investigated by the Economic and Cultural Security Section of the Public Security Corps of Zhejiang Provincial Public Security Bureau. More than 20 days after the college entrance examination, the relevant case has not been disclosed to the outside world. There is no internal notification within the Zhejiang Provincial Department of Education. "So far, everything is still confidential information." Zhou Wei, director of the Propaganda Department of Yongkang Municipal Committee, said.

The receiving device is placed in the ear canal.

A student's parents told Southern Weekend reporter that she also received an invitation before the college entrance examination and paid 50,000 yuan to the organizer to get the answer.

"I heard that if you want to stuff something as big as soybeans into your ears, you may have to have surgery." The parent said that she was afraid of being dangerous to her child's health and being caught. After much consideration, she finally gave up cheating before the college entrance examination began. In the end, she only recovered 20,000 yuan, and the remaining 30,000 yuan was confiscated by the organizer as liquidated damages.

An anonymous person from Jinhua Radio Management Office explained the principle of this cheating method.

"Using the principle of magnetic field induction, cheating students tie the receiver to the body, put the wire in the collar of clothes, and form a loop through the human body. Then insert the soybean-sized terminal receiver into the ear canal. The changes of radio waves and magnetic fields through the off-site transmitter cause the vibration of' soybean' in the ear, generate sound wave induction, and finally emit signals. "

"This technology is not difficult," the person said, but the danger is that this is exactly what the parents of the student are worried about-"('soybean') may not be taken out after being forcibly stuffed in." At that time, students need to go to the hospital for minor otology surgery to take it out.

Once the "soybean" in the ear shakes, it is likely to fall out of the ear and be found. For the sake of safety, many cheaters choose to have a minor operation, put it in their ears and temporarily fix it near the cochlea.

According to the medical anatomical map, the cochlea is adjacent to the depth of the temporal bone and close to the ossicular chain and brain stem of the middle ear. It is difficult to place an object near it by ordinary methods.

As for the walkie-talkie as a transmitter, since the management of radio equipment was liberalized, it has flooded the market and can be bought at any time.

"In theory, walkie-talkies and mobile phones are radio stations. And this soybean-sized one-way receiving device is a miniature radio. " This person analyzed. So the whole process is not a one-to-one relationship understood by the outside world. "A signal sent out is a radio station. As long as there is a receiver, you can receive the signal. We don't know how many recipients there are. In theory, it is even possible to cover the entire test site. "

The way to deal with this kind of cheating is to catch cheating students in the examination room. Otherwise, we can only rely on off-site personnel to testify, "How much is said?"

2 1 foreigner and 9 students were found first. A source from Jinhua Radio Management Office of Zhejiang Information Industry Department confirmed to Southern Weekend reporter: "The first time was 15, and then five times, 1, and the off-site personnel of 2 1 were arrested three times." According to the police, there were 6, 2, 1 students who initially provided services in different places, a total of 9 students.

However, on June 24, what the reporter saw through the Yongkang Public Security Bureau was that a material reported by the bureau to the Yongkang Municipal Committee was different from the previous rumors, and the number became 20 people from different places and 8 students including Cheng.

"At present, all the figures are provisional. The specific case, the public security department is still in the process of investigation, has not yet been finalized. Director Zhang Jianglin, spokesman of Zhejiang Education Examinations Institute, explained to Southern Weekend that the case had been fully taken over by a joint investigation team composed of Zhejiang Education Department and Public Security Department, and the final figures were normal before the investigation ended.

What are the specific figures? How do candidates suspected of fraud put the receiver into the ear canal? The Zhejiang Provincial Public Security Bureau refused the interview request on the grounds that the case has not been investigated and whether to release the news should be decided by the Education Department.

Radio detection of vehicle positioning cheating signal

On the morning of June 5, two days before the college entrance examination, a Toyota off-road vehicle with a spherical radar receiver on its roof has entered the campus of Jinhua Yongkang No.1 Middle School. This "radio monitoring vehicle" with a cost of more than 5 million yuan is specially used to search for cheating violations in the college entrance examination transmitted by radio. "According to the unified requirements of the Ministry of Education, we have made it possible for each prefecture-level city with districts to cover a radio monitoring vehicle before the exam." Zhang Jianglin introduced in an interview with Southern Weekend. The specific dispatch location is "comprehensively determined according to factors such as examination style and discipline in previous years".

An authoritative person of Jinhua Radio Management Office said in an interview that due to the limited monitoring power, Yongkang was finally identified as the monitoring focus by the enrollment departments of nine counties and cities in Jinhua. "Yongkang really should be the focus. Judging from this situation, Yongkang is really powerful and has more signals. " The person who asked for anonymity admitted. "What I learned in the early stage was what regular radio stations were there that day. When I compare them in the next day's exam monitoring, I can find abnormal signals. "

"We didn't stipulate that this car must appear in Yongkang." Zhang Jianglin said, but "Maybe Yongkang had any news a few days ago, so they went to test it." He denied that the Provincial Education Examinations Institute had received relevant reports before.

But the signs seem to exist. A teacher of Yongkang No.1 Middle School observed that on June 5, Xu Yingbo, deputy director of Yongkang Education Bureau, warned in an interview with Yongkang Daily that in order to prevent possible high-tech fraud in the college entrance examination, all localities should check and monitor suspicious signals around local test sites during the college entrance examination, and interfere or block them in time if necessary.

The lens of Yongkang radio monitoring vehicle has also appeared in Shi Jing Station, Zhejiang Province for many times.

On the first day of the college entrance examination, the monitoring car found an abnormal signal near the examination room of Yongkang No.1 Middle School. "We reinforced a lot of equipment that day." A person from Jinhua Radio Management Office said. On the first day of the exam, in addition to the only professional inspection vehicle in the city, another detachable small mobile device was also stationed in Yongkang.

After the first Chinese exam, the staff first used a radio spectrometer to scan the regular frequency band near the test center. Compared with the daily radio station measured the day before yesterday, the abnormal suspicious signal was quickly found. These signals are immediately input to the radio direction finder for analysis, and the signal receiving antenna is used to find and determine the signal emission source. The people present at that time said that after repeated comparisons, the staff set the signal found that morning in the surrounding area of Pepsi Coffee separated from Yongkang No.1 Middle School and No.1 River.

"The precise positioning of the monitoring vehicle is not strong, and only the approximate orientation can be determined." This person said that in order to accurately locate, the staff again used mobile devices to repeatedly monitor and finally determined Baishide. In the second mathematics and the third comprehensive examination, two other launch points were also determined.

The exact location was notified to the police in time. The police of Yongkang Public Security Bureau then dispatched. 2 1 Off-site personnel were arrested on the spot, and then nine students suspected of cheating were identified according to the confessions of the arrested personnel.

The sources of test papers and answers are also included in subsequent surveys. "Originally, we suspected that there might be an act of scanning the test paper and launching it on the spot, but it was not detected in the end." This person said that after interrogation by the public security department, it was finally determined that it was a test paper from other places through the Internet.

Concerns are well-founded. In fact, miniature pen scanners are also easily available in the market. Although the power of this scanner is very small, the receiving range can still reach tens of meters. "As the saying goes, the magic goes up ten feet. It is always after they have new means of committing crimes that we can follow up. " The man said with a wry smile. Fraud is becoming more and more technical and organized, and there are still no effective punishment measures at present.

Yongkang's collective fraud is just one of the radio cheating cases seized in Zhejiang this year.

The Information Industry Department of Zhejiang Province admitted that since the beginning of this year, they have seized eight cases of cheating in the college entrance examination by using radio equipment and technology in Jinhua, Taizhou and Wenzhou, verified 34 people involved outside the venue, seized self-made car platforms 1 3, walkie-talkies 13, mobile phones, laptops and other suspected criminal devices, and intercepted three illegal signals.

Large-scale cheating is related to the new curriculum reform to be launched in 2009. "This year's college entrance examination is a bit special, and next year is a new textbook. Some students take an opportunistic approach. " Zhou Wei, director of the Propaganda Department of Yongkang Municipal Committee, said. The change of new curriculum reform is the update of teaching materials and the change of examination subjects. For many students, if they can't catch the last bus before the implementation of the new curriculum reform plan, they will no longer have the advantage of "reviewing for one year more than others" when they return to high school next year, and everything will become unknown.

Perhaps considering this point, before the exam, Zhejiang Education Examinations Institute repeatedly stressed that it is necessary to increase the punishment for college entrance examination fraud this year.

In the "2008 Enrollment Policy for Colleges and Universities in Zhejiang Province", Zhejiang Education Examinations Institute specially requires every Zhejiang examinee to sign the "Integrity Examination Book" before the examination. Once there is any cheating in the exam, the facts and results of cheating will be recorded in the examinee's electronic file for reference when the school enrolls. At the same time, the record will be included in the integrity platform established at the national and provincial levels, and will accompany the candidates for life.

However, without effective punishment measures, it is impossible to eliminate the real cheating impulse by a self-disciplined honesty.

Guo Shenchu, secretary of the Disciplinary Committee of Zhejiang Education Examinations Institute, admitted that on the day of the Yongkang case, a joint investigation team composed of the Provincial Department of Education and the Public Security Department immediately rushed to the local area. But until the deadline, no one was punished.

Guo Shenchu explained to the Southern Weekend reporter that once it is confirmed that there are students cheating, different punishments will be given according to the seriousness of the case. The first is to catch it on the spot and cancel the single subject score; The other one is serious. For example, students caught in the last game will be disqualified if there is evidence of cheating in the previous game. The third is to send test papers to the outside world and reveal state secrets. "This involves criminal issues, so it is out of our control."

Guo Shenchu said that because Yongkang cheated in the college entrance examination, no students were caught red-handed, and all the students suspected of cheating were identified by cheaters off the court afterwards. Therefore, so far, no students have been disqualified from any course. Because there is no final investigation conclusion, all students suspected of cheating in Zhejiang Province have not been punished at present.

"This is related to their lives. We are very concerned about students' grades. We won't give them this conclusion easily until the conclusion of the public security department comes out. "

The Zhejiang Provincial Department of Education denied that any teachers had been dealt with. "Whether the teacher handles it or not can only be determined after the survey results come out. Our provincial office and the Commission for Discipline Inspection have not received this news. "

A person from the Information Industry Department of Zhejiang Province, who asked not to be named, said that almost all of the senior high school entrance examination, college entrance examination, judicial examination and postgraduate (Q bar) examination can be fixed for life. Before the illegal cost was low, exam fraud has now shown the characteristics of gang and organization, which is "impossible to prevent".

This person recalled that once he was in charge of monitoring in Jinhua No.1 judicial examination room, and he was suspected of cheating, but he was still unable to make a punishment. A parent said angrily after hearing the news, "If it is only 65,438+10,000 yuan and 200,000 yuan, I will let my son do the same."

The lack of laws on how to punish cheating in exams may be another reason. A prosecutor from the Hangzhou Procuratorate, who asked not to be named, commented that the current Law on Public Security Punishment and the Criminal Law do not clearly stipulate the punishment for organizing fraudsters, unless these members are suspected of leaking state secrets for stealing test papers. Besides, there are no effective criminal punishment measures.
