Eavesdropping on 3D printers allows reverse engineering of sensitive designs


3D printers have opened up all kinds of possibilities when it comes to turning digital blueprints into real word objects, but might they also enable new ways to pilfer intellectual property?... 

While the source code for 3D printed designs can be guarded through encryption and regular means, once the machine is swung into action that sensitive information may be compromised, researchers at the University of California Irvine (UCI) have discovered. 

Led by Mohammad Al Faruque, director of the Advanced Integrated Cyber-Physical Systems lab, the team found that placing a smartphone alongside the machine as it printed objects layer-by-layer enabled them to capture the acoustic signals. It says that these recordings contain information about the precise movement of the nozzle, and that information can later be used to reverse engineer the item being printedmore
