Identifying iPhone name/user (Device ID?) for photo processi

Hi --

I have a Hazel workflow for processing incoming photos from various sources (forums have been a huge help -- thank you!). The workflow collects the photos, renames them including a device type and date. For example, Hazel renames "IMG 5144.jpg" to "IMG 5144 - iPhone 5 - 2015-02-21.jpg".

My wife has asked whether it is possible to further tag the photos to determine which user it came from, in order to distinguish photos taken with her iPhone 5 from those taken with my iPhone 5. So we'd like to end up with photos named something like:

IMG 5144 - Ramon's iPhone 5 - 2015-02-21.jpg

Is there a way to retrieve a username or device-specific identifier from EXIF data embedded in iPhone photos?

Thanks,

Ramon

Not sure but if you select one of the files in Finder and do "Get Info", you'll see all the data available (mostly under "More Info"). Maybe there's something there you can use to differentiate between the two.
