The camera on your phone might be the best defense you have | The Verge: "Could your cellphone camera give a boost to cryptography programs that help protect your data? That was the pitch that surfaced in a paper this week from a group of researchers at the University of Geneva. The paper studied the visual noise patterns from the camera on a Nokia smartphone, digging deep enough to track quantum fluctuations (tiny, temporary changes in the amount of energy at a point in space). If used right, those fluctuations could provide a source of perfectly random noise that would make a huge difference in future encryption protocols."
