This week's stories show how fast attackers change their tricks, how small mistakes turn into big risks, and how the same old tools keep finding new ways to break in. Read on to catch up before the ...

Abstract: Photodiode-based visible light positioning (VLP) systems can achieve centimeter-level accuracy, high positioning frequency, and low signal processing complexity. Thus they can serve as ...
