L' INTELLIGENCE CYBER par Jean-Paul Pinte

A man with one hand in his pocket approaches a locked door and places his other hand on the doorknob. A second later, the deadbolt clicks open, as if by magic, and he lets himself in. A would-be burglar casing the house watches this sequence of events unfold. The next day, after the man has left for work, the burglar approaches the door and places his hand on it, expecting it to pop open. Instead, it stays stubbornly locked. It’s not outfitted with a typical “smart lock,” which uses Wi-Fi or Bluetooth to open when a paired phone or watch is nearby. It’s not reading his fingerprint, either. So what’s going on?
