Exif 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.
