Those trying to communicate will always have the advantage thanks to cryptography. It gives you many way to secure and obfuscate communications, even in plain view.
- ben_w 6y agoI disagree. Surveillance isn’t limited to breaking encryption — the Stasi would put cameras in water cans to spy on funerals, drill holes in walls while you were out to spy on you in your own apartment, etc. — and the tech for meatspace surveillance has only gotten smaller and cheaper since the fall of the Wall. Laser microphones in particular are something a high school student could reasonably make with a pocket-money budget.

- ben_w 6y ago> It works best with a small hardware extension (a small speaker/headphone) to focus the sound on the mic, making it silent its surroundings. An idea how to build it is found in the Menu. Great when you know where the microphone is but can’t leave the area for a private chat; not so useful when the microphone is any nearby substance that reflects some wavelength and which vibrates enough when exposed to sound that the reflected light can be decoded.
