Sound Security: Researchers Find a Novel Threat to 3-D Printer Data

To the average visitor to the RapidTech prototyping center at University of California, Irvine, the methodical buzz of its 3-D printers would be nothing more than background noise. But to Mohammad Al Faruque, that hum is valuable information. A professor of electrical engineering and computer science, Al Faruque directs the university’s Advanced Integrated Cyber-Physical Systems lab. There, he and his graduate students worked with RapidTech, a nonprofit educational shop that builds specialty items such as airplane parts for businesses, to teach a computer to copy a 3-D printed object’s shape using only an audio recording of its creation. It’s a feat of reverse engineering that he thinks industrial spies could use to steal otherwise encrypted design files. “President Obama has said he wants to bring manufacturing back to the United States,” says Al Faruque,…
