Those fingerprinting techniques are impressively clever! Is there any known way to thwart them on Android? I imagine that TikTok isn’t the only app doing these things.
I think the first part (data being sent to Facebook) was also covered in a 35C3 talk. It seems to be used in a wide variety of apps. If somebody is interested: https://media.ccc.de/v/35c3-9941-how_facebook_tracks_you_on_android
The fingerprinting techniques are quite “impressive” (in a negative sense). I was still under the impression that fingerprinting is done based on viewport size, enabled plugins, etc. Do I see it correctly that these graphics and internal audio recordings could not be even blocked with TOR browser?
