Geo guessing is related to open source intelligence techniques, and it’s pretty easy to get surprisingly good at it.
People who are good at it can take a picture of someone’s room and deduce enough about them (sometimes) to be able to get their name, address and phone number.It being automatic is pretty cool, but you were already leaking the information to anyone interested.

This Just In: Most photos uploaded to the internet are not stripped of their metadata, and one of the common things kept in metadata is… (drumroll please)… your GPS coordinates.
This is a lot less interesting than it seems to be at first glance, imho.
Literally just after talking about how people are spouting confident misinformation on another thread I see this one.
Twitter: Twitter retains minimal EXIF data, primarily focusing on technical details, such as the camera model. GPS data is generally stripped.
Yes, this is a privacy thing, we strip the EXIF data. As long as you’re not also adding location to your Tweet (which is optional) then there’s no location data associated with the Tweet or the media.

People replying to a Twitter thread with photos are automatically having the location data stripped.
God, I can’t wait for LLMs to automate calling out well intentioned total BS in every single comment on social media eventually. It’s increasing at a worrying pace.

Some digital cameras and phone cameras can also embed the GPS coordinates in the pixel data so that even if you delete the EXIF metadata the GPS location and device serial number are still present in the image. Many document printers also embed device serial number and other data on printed documents by using nearly invisible dot encodings.
That’s crazy. Just read this and I’m just mystified
Back in like 2006 or 7 steganography was used in obscure corners of the internet ( like insurgen.cc, an early anonymous holdout that got broken up by the feds) to pass around hacking tools. You’d unzip the dangerous kitten photo with winrar and extract a set of hacking tools. One I remember passed around widely was the low orbiting ion cannon the /b used to ddos scientologists.
The tweet:
(Is the preview working for you? For me, it’s not).
The game is called geoguessing and those who do this regularly are crazy good at it, taking into account the kind of trees you see, where the sun and shadows are, even the color of the dirt and the pavement.
Tom Scott did something similar and was frightened too: https://www.youtube.com/watch?v=cGqEBvlmFAQ&pp=ygUSdG9tIHNjb3R0IGZvdW5kIHVz
important second frame for context!
& no it isnt. quite sure twitter broke link previews a long time ago alongside guest accounts.
which llm does he use
Looks like Pigeon or Pigeotto https://huggingface.co/papers/2307.05845
tragic that it doesnt include a gguf or safetensors file for easy access. ill load it up eventually. this would be very useful for invasive animal research
