Note to self: Always, always, ALWAYS strip exif data.
- Kiboneu 4y agoYou’ve confused the data with the metadata.
- bfgoodrich 4y ago
- Denvercoder9 4y agoExif data is the metadata of the image.
- lmm 4y agoExactly, whereas stars shown in the image are just data, you don't need the exif data to see them.
- insane_dreamer 4y agoBut the time the photo was taken was extracted from the exif which is what OP was referring to stripping
- lmm 4y agoIf you can see stars, satellites and planets you can figure out the time. It makes the problem a little harder (you've got to locate a point in 2+1 dimensional space rather than on the 2 dimensional surface of the Earth), but it's not a fundamental difference.
- Kiboneu 4y agoThe lesson here isn’t to strip exif data, though. It’s to identify information that can be connected to anything to infer metadata that you want to keep hidden. If you always wipe exif data, and don’t investigate your pictures, then you will eventually neglect some combination of data points someone could use to infer richer context.
- jwilk 4y agoNo, Exif is an image format. https://en.wikipedia.org/wiki/Exif https://en.wikipedia.org/wiki/Exif
- riffic 4y agometadata is actually a form of data, believe it or not.
- pjot 4y agoThe data’s data!
- quickthrower2 4y agoMetadata is data, but without legs
- a1369209993 4y agoI assumed that was the joke? If they're finding the location based on the stars in the image, you'd need to strip out the actual image data (not metadata) to prevent that.
- lortrq 4y agoI would like to know what else is embedded in digital pictures, similar to the printer yellow dots, except it will be undetectable.
- colechristensen 4y agoSensor noise has been used to successfully identify the camera used to take a picture. No embedded features just the physical characteristics of sensors being individual enough to identify.
- nomel 4y agoCouldn't the same conclusion be reached, without? That plane flying overhead, center, would probably make things much easier.
- IIAOPSW 4y agoAlways, always, ALWAYS black out the sky.
- PebblesRox 4y agoPlot twist: they replaced the sky with a different starry background.
