When uploading a real recording, there is a good chance your location & therefore possibly your identity can be revealed from the footage itself.
You can triangulate low volume background sounds such as air planes: https://cybernews.com/privacy/aircraft-doppler-audio-geolocation-privacy/
You can check the position of the sun/moon/stars, shadows, weather…: https://www.bellingcat.com/resources/2020/12/03/using-the-sun-and-the-shadows-for-geolocation/
If Streamers & Journalists CAN do it, government agencies ARE doing it.
If you need privacy be aware of this when recording / editing friends <3
Not any air planes it needs to be a propeller plane.
I’ve watched the full video and from what I understood, it does not need yo be a propeller plane. They recognized a propeller plane from the audio, and used this info to narrow down the ads-b dataset, but it could have worked with any other type of plane as long as you can find a Doppler curve in the spectrogram
Anything that you can use that has a Doppler shift and is detectable by a camera will and can be used to locate. In the way it was done on the video it was layered with aircraft traffic. Even with a jet engine it will still have a Doppler effect. Unless you’re flying a glider that is silent you can be found. That ONLY by just this method.
And when I comment to people that privacy is literally dead if you use tech I get told I’m stupid when this guy on fucking YouTube found a location with the Doppler effect. No matter what you do or what you use you can be found with technology. Cry about proton failing and move to you’re new “secure” apps.
