The Visual Microphone: Passive Recovery of Sound from Video (YouTube): https://www.youtube.com/watch?v=FKXOucXB4a8 Using video (even consumer video) to recover sound from silent video, even from outside rooms. Using a laser bouncing off window glass has long been a technique for recovering room sounds remotely. The technology described here emphasizes the need to keep external windows completely covered during sensitive communications! Also, we can safely assume that intelligence agencies (at a minimum) have been using this technique for some time. --Lauren-- Lauren Weinstein (lauren@vortex.com): http://www.vortex.com/lauren Founder: - Network Neutrality Squad: http://www.nnsquad.org - PRIVACY Forum: http://www.vortex.com/privacy-info Co-Founder: People For Internet Responsibility: http://www.pfir.org/pfir-info Member: ACM Committee on Computers and Public Policy I am a consultant to Google -- I speak only for myself, not for them.
