Is a picture without personally identifying information problematic? I assume pre-COVID you didn't walk around in a mask all the time.
If you have all the original metadata in a typical smartphone camera JPEG, then things like the info below is available:
- camera model
- phone model
- time & date of when the picture was taken
- geo-location of where the picture was taken
I would say for anyone motivated enough that is pretty easily identifiable.
edit: bullet points formatting
edit2: lewispollard rightly pointed out that I should read before writing. :)
