YouTuber shows aircraft noise in a video can reveal where it was filmed

The sounds in the background of your videos could give away where you are. TechRadar reports that security researcher and YouTuber Colsto has shown that aircraft noise can be used to geolocate a video to within around 100 metres

The technique isolates the sound of passing aircraft, matches the changes in pitch caused by the Doppler effect to public flight tracking data, and triangulates using several planes. It can work from under a minute of audio

The demonstration used US flight data and audio from security cameras. Colsto has not released a tool, and common audio fixes such as high pass filters and noise reduction may not defeat the method

Colsto said the odds that someone can and does do this are pretty slim. However, he added that something with zero visual clues could be located using this technique

This is a fascinating reminder of how much information hides in ordinary media. Most people check videos for visual clues like street signs, but few think about background sounds. For anyone who needs to keep their location private, muting or replacing audio may be the safest option

Does this make you think differently about posting videos online? And what other hidden clues could reveal where you are?
