Smartphones Can Steal 3D Printing Plans By Listening To The Printer (fedscoop.com) 45
An anonymous reader quotes a report from FedScoop: Smartphones equipped with special programming can become a sophisticated spy sensor capable of stealing designs from a 3D printer -- just by measuring the noise and electromagnetic radiation the printer emits. Researchers from the University of Buffalo recently discovered how a smartphone on a bench about 8 inches away from a 3D printer could allow someone to reconstruct a simple object being printed with 94 percent accuracy. Complex objects can be copied with 90 percent accuracy. The attack basically reverse-engineers the printing blueprint by reconstructing the movement of the nozzle from the electromagnetic and acoustic energy it generates while working. Most information came from electromagnetic waves, which accounted for about 80 percent of the useful data. The remaining 20 percent came from acoustic waves. Wenyao Xu, assistant professor in the University of Buffalo's Department of Computer Science and Engineering, is the lead author of the study, "My Smartphone Knows What You Print: Exploring Smartphone-Based Side-Channel Attacks Against 3D Printers," which will be presented at the Association for Computing Machinery's 23rd annual Conference on Computer and Communications Security next month in Austria.
