Then they'd have a signature of reflecting less than surrounding. In the long long run, probably more robust to detect the entropy generated by computation in a physical area (i.e. heat) and not the optics.
- frizensami 5y agoAgreed. I expect however that any easily available thermal sensing, especially on smartphones (see FLIR, etc), could be easily defeated with a strong adversary doing good thermal management. As you say though, extra heat is a physical guarantee, so maybe a smarter technique exists to separate signal from noise in the thermal domain that I don't know of yet.
