And suddenly, privacy invasion gets off the table quickly (as soon as you are not aiming for 100% non-cheaters, the cost becomes obviously too high for everybody else).
As far as reputation, I'd rather see schools focus on the successful students, which is somewhat done with all those research-paper-grading systems (not a perfect system by any means because of gamification, but at least idea in the right direction), but mostly done with bragging about scientific break-throughts to come out of their students and staff.
Still, what is the purpose of a reputation or "well-respected degree"? The goal should be knowledge and applicability of that knowledge to actual problems in life (known as "jobs"): it's not like anyone accepts any graduate without interviewing them first, which is to say that nobody trusts any school to have done a proper job of evaluating them. Most of those schools don't trust themselves, so they hold interviews for post-graduate studies too! :D
Nobody looks at the "lemons" coming out of a school to consider it a bad school (I am sure you can find plenty from "top" universities too), but on the successful ones. Do the successful ones change with more cheaters at all? (Sure, there is a turning point, but catching all of them is meaningless)

> Unfortunately custom projects and the like won't work for teaching fundamental maths skills.
I am not sure I agree. One of the projects I did for my projective geometry class was to do an inverse of a projected drawing (in AutoCAD) and save a 3D .obj file. In differential equations course, I was given a project to prove a theorem that is generally missing from the school books (or usually given as an exercise). You can also let people devise proofs in a closed system of axioms and a few theorems.
It is a hard and different type of work, but I am certain you can both teach and get to know students with theoretical math projects. If they get someone else to do it for them, yet they are able to present it in front of the class (online) convincingly, they have likely understood the concepts, which is what teaching is all about.
While I am against these surveillance software, making sure that tests are fair is very hard, especially since everything is online now thanks to COVID.
A sibling program at the university exposed a cheating ring of ~15-20 people, and I think many were surprised that the result was to simply zero their grades for that class instead of more severe action.
/e I mention incidents and sizes since these programs are not thousands of students but tens or hundreds.
It sounds like the definition of cheating was very broad there.
I think cheating is quite common in the undergrad years, but gets less later.
As the original commenter notes, here the problem is being solved for "well-behaved" students, in a way which is easy enough for dishonest students to bypass and present themselves as well-behaved.
