This is a fun thought exercise.

Pen and paper only? Lock them in a faraday cage to keep RF from going in or out? RF jamming? In-person testing only. No devices, period. Supply hearing aids, glasses and even clothing if you have to.

AI systems can be fooled, people can be bribed, cameras and detectors can miss things. To me it's a risk vs reward equation. If the risk of getting caught is greater than cheating, people will generally not want to cheat. If there is no risk at cheating and only something to gain, cheating will be rampant. If you get caught cheating and there is no jail time, no financial risk, and you can take the test again... why not cheat? Make the barrier to cheat incredibly high and the cost of cheating even higher.
