At present, the anti-cheating function of the online examination system is still very complete. First, manual invigilation can be used. There are three main ways of manual invigilation. The first is to organize inspection of the examination room, the second is to remotely check the examination room monitoring, and the third is to review the monitoring information of the system.

These are the main methods of manual invigilation. The reason why invigilators' invigilation work is easier is mainly because the online examination system itself has powerful invigilation control function. The general online examination system can limit the cheating behavior of candidates through the following aspects:

1. Time limit for answering questions.

The answer time can be limited for each question. If there is no answer after the timeout, the system will automatically jump to the next question, so as to minimize the possible cheating time of candidates.

2. Random order.

random order of questions and random choice of multiple-choice questions are supported, which makes it difficult for candidates to transmit answers to each other.

3. Prevent screen cutting.

During the examination, candidates are not allowed to cut or split the screen, otherwise the system will automatically hand in the papers and end the examination. At the same time, candidates who trigger the anti-screen-cutting rule and automatically hand in their papers will be marked as "suspected cheating" in the test results to cause eye-catching prompts to the administrators.

4. Face recognition.

Before the exam, face recognition will be conducted to confirm the identity of candidates, and taking the exam instead is absolutely not allowed.

5. Camera monitoring.

During the examination, the system will use the camera to shoot the examination pictures of candidates at random times, so as to avoid face recognition before taking the test, and also to prevent candidates from reading and viewing offline materials to cheat during the examination.

6. Handwritten signature.

Everyone's writing habits are different. Without deliberate imitation, handwritten signatures can be used as an auxiliary proof to confirm the true identity of candidates.

7. terminal is prohibited.

administrators can ban certain test terminals, such as mobile phones, computers, web pages, etc., thus forcing candidates to use the terminals allowed by the test.

8, the screen test.

An independent program will be used for the examination. During the examination, candidates can't leave the examination screen, and the examination environment is always at the top, which will cover any old and new windows. Only when candidates hand in their papers and leave the exam can the examination environment be closed.
