Method for preventing cheating by adopting face tracking technology based on camera in online examination

Abstract

The invention discloses a method for preventing cheating by adopting a face tracking technology based on a camera in an online examination. The method comprises the following steps: S1, starting a face recognition technology and a living body detection biological recognition technology; s2, starting a face tracking technology, and marking the face position of the examinee in real time in a video monitoring area of an examination answering page of the examinee; the face tracking technology comprises three modes, namely a multi-person mode, an unmanned mode and a random mode, and the face tracking technology records a face coordinate change curve; and S3, uploading the collected facial coordinates to a terminal, and determining whether the examinee cheats by adopting video attacks and virtual cameras. A face tracking technology is added on the basis of a living body detection biological recognition technology, the face tracking technology comprises a multi-person mode, an unmanned mode and a random mode, the unmanned mode and the multi-person mode can effectively reduce the misjudgment phenomenon caused by the fact that the faces of examinees are not all in a camera viewing frame during photo snapshot in examination and verification, and the examination efficiency is improved. And the workload of manual confirmation of teachers is reduced.

Description

technical field [0001] The invention relates to the field of online anti-cheating, in particular to a method for preventing cheating based on a camera and using face tracking technology in online examinations. Background technique [0002] With the development of online education, online examinations are widely used in various examinations. Especially in some special scenarios, remote examinations have become a commonly used and effective form of examinations. a problem. Especially in distance education, how to distinguish and identify students who have really participated in online assignments and online exams is more difficult. [0003] Existing methods to prevent cheating in online exams generally use a PC client to conduct exams, using exam software to monopolize (dominate) the screen, shield external multi-monitors, virtual machines, IM communication software, and a series of security checks. During the exam, only When using the test software, other software cannot be...

Problems solved by technology

Even if there is an existing dual-camera solution, the cost of this solution is relatively high, and multiple teachers are required to monitor the test site in real time. The cost of broadband and the labor cost of the invigilator are very high. In actual general tests, it is often difficult to Scale put into use
