Android and iOS devices impacted by new sensor calibration attack

SensorID attack

A new device fingerprinting technique can track Android and iOS devices across the Internet by using factory-set sensor calibration details that any app or website can obtain without special permissions.

This new technique — called a calibration fingerprinting attack, or SensorID — works by using calibration details from gyroscope and magnetometer sensors on iOS; and calibration details from accelerometer, gyroscope, and magnetometer sensors on Android devices.

According to a team of academics from the University of Cambridge in the UK, SensorID impacts iOS devices more than Android smartphones. The reason is that Apple likes to calibrate iPhone and iPad sensors on its factory line, a…
