In academia, professors are quite concerned with cheating right now, when all teaching happens online. Some professors are considering using software to randomize the exams, so no two exams are identical. This obviously increases the grading effort. Some are asking students to take a pledge, like "I solemnly swear to not google the problem". Some are just trusting the students to not cheat. There's no easy and universal solution. Ideally, technology could solve the issue, but it's not that easy to identify and implement a technology solution in a matter of weeks.
