Quite often when out at dinner, you will take your keys out of your pocket and place them on the table in order to feel completely comfortable - but what if this meant that random people on the internet could then enter your house with ease?
According to Håkan Hedlund from the Swedish Theft Prevention Association, burglars can pinpoint a Facebook photo in which your keys are displayed, enhance the finding (CSI pun intended), model this find on their own computers and print out the exact design on a 3D printer - using this to open your front door. In a chat with PC World, Hedlund stated "Yes, it's possible to copy a key from a photo, in any case if it's a fairly simple key."
With 3D printers being made more accessible to the public, Hedlund recommends you keep your keys in a safe place. Anton Månsson reaffirmed this risk, commenting that keys don't have to be made out of metal to work efficiently "You can use many different kinds of thermoplastic, nylon or wood-plastic composites, but none of the simpler 3D printers can use metal."
