• Staff is a member of the course staff. They can see the data of all users, and depending on course settings may have permission to edit the information of other users.
• Student is a student participating in the class. They can only see their own information, and can do assessments.
• None is a user who at one point added the course and later removed themselves. They can no longer access the course but their work done within the course has been retained.

Client fingerprints are a record of a user's IP address, user agent and sesssion. These attributes are tracked while a user is accessing an assessment. This value indicates the amount of times that those attributes changed as the student accessed the assessment, while the assessment was active. Some changes may naturally occur during an assessment, such as if a student changes network connections or browsers. However, a high number of changes in an exam-like environment could be an indication of multiple people accessing the same assessment simultaneously, which may suggest an academic integrity issue. Accesses taking place after the assessment has been closed are not counted, as they typically indicate scenarios where a student is reviewing their results, which may happen outside of a controlled environment.

The "Duration" is the amount of time that a student has spent actively working on the assessment. The duration time measurement begins when the student starts the assessment and continues until the most recent answer submission.

For Homework assessments, a student is considered to be actively working if they have at least one answer submission per hour, so the duration measurement is paused if there is a gap of more than one hour between answer submissions. For example:

• 08:00 - student starts assessment;
• 08:30 - student submits answer;
• 09:00 - student submits answer;
• (gap of more than one hour)
• 11:00 - student submits answer;
• 11:30 - student submits answer;
• 12:00 - student submits answer.

In the above example, the "duration" would be 2 hours: one hour from 08:00 to 09:00, and another hour from 11:00 to 12:00. The two-hour gap between 09:00 to 11:00 is not counted as part of the duration.

For Exam assessments, a student is considered to be actively working between the start of the assessment and the last submission, regardless of any potential inactivity. For the same example above, the "duration" would be 4 hours, from 08:00 to 12:00. The two-hour gap is not considered inactivity, since it is assumed that this kind of assessment requires students to be active for the duration of the assessment.
