Do phone camera apps not have options to strip metadata? I've never owned a smart phone but even my DSLR's will embed proprietary metadata that has make/model and encrypted serial number. Some cameras don't encrypt the serial number.

As a fun experiment, one could modify the exif data using tools like exiftool / exiv2 / ImageMagick mogrify to strip or even change the metadata. Perhaps make the AI think you are traversing the North Pole moving at mach-4. What other silly things could one do to the AI?
