The very first comment of this thread says: "Browsers only sample sensor data at a varying 67Hz (drops down to 1Hz sometimes)". Research-wise, sensors at any frequency (even 20 Hz) are able to reveal something about the user's activity (touch actions, PINs, etc.) or his surrounding environment. We can't say 5 hz or 60 hz or 200 hz is safe or not. However, the higher frequency, the better attack results; the lower frequency, the more expensive machine learning techniques, the attackers will find their way through anyway. That is why we advise to have design-level security models rather than implementation limitation solutions i.e. playing with the sampling rates. -- GitHub Notification of comment by maryammjd Please view or discuss this issue at https://github.com/w3c/sensors/issues/98#issuecomment-281339687 using your GitHub accountReceived on Tuesday, 21 February 2017 13:08:37 UTC
