Pointing a telescope at tens of meters away will get you noticed pretty quick. Now one can sell lightbulbs with noise modulation to defeat it.

- hedora 6y agoYeah, not sure why they patented the attack, and not the defense. It seems much easier to enforce a patent against technologies that defeat the attack. From the article, it looks like one can build the surveillance device from a few readily available parts, and then hack together the signal processing software. That’s not even in violation of the patent if you don’t sell / distribute it.
