possible information that an image could contain which could identify an individual?

• The serial number of your camera (and your lens). For a camera this could be a bit hard to track, but for a smartphone, the constructor can certainly map the S/N to an IMEI, and the network operators can map the IMEI to a number and the number to a customer. 
  
• Anything you have put in the "Artist", "Copyright", and "Owner name"
  

OTOH, I see these things in my DSLR pictures but not in my phone, where the pictures are more anonymous (besides the GPS data of course).

So this is camera-dependent, and the best way to tell is to take pics from your usual camera(s) and run them through and EXIF analyzer (ExifTool or else) and see for yourself.
