It's already against the rules to cover your face in many schools. Besides, if the system can't recognize you, you will be marked as absent - so the punishment for defeating the surveillance system is the same as the punishment for breaking the rule it's intended to enforce. Those teenagers are dependent on the civic involvement of adults, they can't save themselves.
In the 90s/2000s we were taunted with a nefarious “permanent record” that recorded all our evil deeds. Do they still use that on students? It even came up in a few Simpson’s episodes.
Somehow I haven’t seen anyone actually be negatively affected by this supposed record.
If the system is subject to false positives, students will figure out a way to exploit that, e.g. marked as present when absent via 'masks', Mission Impossible-style.

I can assure you, the teams of PhDs from Stanford and MIT will address those cases. Just like how Google knows if you're clicking random ads.
