The plugin allows you to compare the image taken from the user's webcam, when accessing the quiz, with their profile image. If the two images portray the same person, access to quiz is authorized. ​The plugin continues to monitor the user framed by the webcam even during the execution of the quiz, blocking the execution as soon as it detects a different person. Users can upload their image directly from the control interface, without therefore having access to the standard profile editing page.
