Privacy is Consent (alt: On Optimal Privacy vs. System Efficiency)
This fieldnote documents my notes with regards to a characterization of systems I’ve been calling “optimal privacy” but which intersects and overlaps with many other concepts in the literature e.g “privacy and computational complexity” or “approximate privacy”. Starting with an observation, it is clear that privacy-preserving protocols are less efficient than non-privacy preserving protocols - that is to say that it seems that one must always communicate more to say less.
