Real-time voice concealment algorithm blocks microphone spying
19-Apr-22
Researchers at Columbia University have created a new algorithm that can prevent rogue audio eavesdropping via microphones in smartphones, voice assistants, and other connected devices.
The algorithm is capable of working in a predictive manner. It predicts what the user will say next and creates obstructive audible background noise (whispers) to drown out the sound in real time. Read More…
