The Sounds a Key Make Can Produce 3D-Printed Replica

Researchers reveal technology called SpiKey that can ‘listen’ to the clicks a key makes in a lock and create a duplicate from the sounds.

Security researchers have given a whole new meaning to “picking a lock,” demonstrating that they can use audio and signal-processing technology to listen to the sounds a key makes when it opens a lock and then 3D-print a duplicate from a recording.

The attack, called SpiKey, leverages any basic recording technology—such as the one found on any smartphone—and pairs it with signal processing software that can listen to the time difference between audible clicks of a key to determine its particular shape. That shape can then be transformed to a computer model that can be 3D-printed.

A team at the National University of Singapore developed the attack, which is the brainchild of Soundarya Ramesh, a first year Ph.D. student in computer science at the university.

SpiKey “significantly lowers the bar for an attacker” who wants to break into someone’s house or anything else protected by a physical lock, she and her fellow researchers wrote in an abstract for a paper (PDF) on the research. The team presented the work in early March at the 21st International Workshop on Mobile Computing Systems and Applications (HotMobile 2020) in Texas.

    I will now whistle loudly when locking and unlocking. Problem solved.

    A really interesting concept, but I just ask myself....why? To hear the key in the lock you need the key anyway, or be close enough to record the key being turned. I’m not sure your average burglar will possess long range listening and recording equipment and 3D printing facilities will they?
