Mind-reading and law enforcement

When does law enforcement's demand to read your data become a demand to read your mind? (via Communications of the ACM)

We fear we are slowly moving toward the era of universal mind monitoring without having recognized and considered it in those terms. And those are the terms in which we should understand battles about the right to use effective cryptography.

This article glosses over a lot of implicit beliefs, especially that mind happens inside the brain. (I'll leave alone the question of what the authors could mean when they discuss "accurate" thoughts). However, in connecting mind-reading machines back to concerns around privacy, this article makes a nice contribution.

The authors make no specific recommendation on how cryptography may help the mind-reading threat model. Perhaps differential privacy is part of the solution.
