Security features to prevent cheating rely on a mix of monitoring, data analysis, and access control. Real-time surveillance, such as cameras and screen monitoring, can detect suspicious behavior. Systems often use data analysis to identify irregularities or patterns that suggest cheating, like unusual answer patterns or frequent account access from different locations. Access control features, such as identity verification and timed exams, ensure only authorized users participate and limit opportunities to cheat. Together, these measures help maintain fairness and integrity by detecting and preventing dishonest activities.
