Exploiting Temporal Misalignment of Inertial Measurement Units for Acoustic Eavesdropping on Smartphones

A novel technique called STAG (Sensor Fusion via Temporal Misalignment in Accelerometers and Gyroscopes) that exploits the temporal misalignment between accelerometer and gyroscope data to circumvent Android's 200 Hz sampling rate limit and enable effective acoustic eavesdropping on smartphones.
