China fights college entrance exam fraud with AI

Beijing [China], June 8: The South China Morning Post newspaper on June 8 quoted Chinese media sources as saying that Guangdong , Hainan and Shandong provinces have used "AI patrol systems" to monitor exams and ensure transparency in exams. .
According to China's Ministry of Education , there are 13.4 million candidates registered for this year's Gaokao exam. This is a record number of candidates ever recorded.
According to Guangdong Daily , Guangdong province has deployed AI on 386 exam sites to detect cheating, plagiarism and other unusual behaviors through image and video data. If strange signs are detected, the system immediately signals the supervisor to take remedial measures. However, in all cases, verification and final decision if there is a dispute will rest with the competent officials.
In previous years, Chinese officials applied technology in the Gaokao, considered one of the most fierce university exams in the world. China in 2015 deployed drones to detect fraud. Since 2016, cheating during the Gaokao period can be considered a criminal offense.
The research team in Sichuan province said AI can monitor large amounts of surveillance video, helping to shorten review time. To develop anti-fraud AI, it is necessary to collect and annotate large amounts of data about what behavior is considered anomalous.
Computer vision technology is used to capture and process images in the exam environment, extracting image features. Machine learning algorithms will then train based on these image characteristics to establish a model that identifies abnormal behavior in exams, which can be applied to real-time exam monitoring.
