Robot vacuum cleaners can be used by hackers to 'spy' on private conversations: NUS studyDec 07, 2020 | 🚀 Fathership
Computer scientists from the National University of Singapore have demonstrated how a common robot vacuum cleaner and its built-in light detection and ranging sensor could be used to "Spy" on private conversations, the university said on Monday.
The method, called LidarPhone, repurposes the Lidar sensor that a robot vacuum cleaner normally uses for navigating around a home into a laser-based microphone to eavesdrop on private conversations.
In their experiments, the researchers used a common robot vacuum cleaner with two sources of sound - the voice of a person reading out numbers played from a computer speaker and music clips from television shows played through a television soundbar.
INTERNET CONNECTED DEVICES POSE PRIVACY RISKS. To prevent Lidars from being misused, people with robot vacuum cleaners are advised to not connect them to the Internet.
