Original description:
On my Samsung Galaxy S3 I can face tag people/faces that are in my Android address book.
It would be great if these tags could be recognised and matched against tags from Shotwell.
I fear that the mobile handset saves not the name but a contact number into the photos but I'm sure there are ways to get this working.

Attached are two files.
The first picture is with one person tagged on the Galaxy S3 device. The second is from the file property dialogue.

If your hunch is right, it looks like the camera has stuffed this information into the Exif.Photo.UserComment field, which on the image you've supplied is a 4096 binary blob. UserComment is defined by EXIF to allow multibyte text descriptions, but I suspect the camera has simply repurposed this field for binary data.
If Shotwell was to support this, we would need some kind of specification detailing the data format of the face tags. It would also be nice to know that this is some kind of standard among camera manufacturers and not Samsung's home-spun data format. (It would be really nice if they'd used XMP for this, but they have not.)
We can't proceed until the above questions are answered. Also note that this could work very well with the Faces branch rather than generated Tags from the face recognition.
