When I import photos from my iPhone, they all fall into one huge list of files: IMG_4649.JPG, IMG_4650.JPG, IMG_4651.PNG, ... There are pictures that I took myself, the image of friends, I have an image I uploaded and made screenshots.
I'm looking for a way to programmatically find out if I took a picture myself or not. If the iPhone stores the serial number in EXIF data, I could use it, but it is not.
Is there any other information about a particular device stored in photos? Only the model does not help me, as others take pictures with the same model.
