Maybe this too radical to be useful here, but it occurs to me that 
there's a philosophical argument (at least) that the 'holder' is 
actually the 'owner'. As follows:

If Jane has a university degree, let's say a BSc, issued by let's say 
MIT, and let's say it was issued ten years ago (just to give a context) --

Jane says, in normal human speech with other people:
"I have a BSc. It's from MIT."

Jane is then the owner of the BSc, in normal, non-specialized human 
understanding. It's her BSc. The fact that it came from MIT is merely 
an attribute of her BSc. In fact, usually she wouldn't even mention 
it. "I have a BSc" would be the more common usage.

And in normal human speech, we wouldn't say MIT 'has' or 'owns' Jane's 
BSc. This is logical, because MIT can only issue a BSc if it's further 
accredited by a government, or by an association of universities. So 
MIT is only partially responsible for its power to issue the BSc.

But, before this *specific* BSc was issued, it didn't even exist. It 
was issued so that Jane and only Jane could have it. So, in effect, it 
wouldn't be surprising to say she owns it, IMO.

I see that there are other ways to interpret this, but it has a major 
advantage of being part of the everyday usage in our society.

And if we started from that -- with 'owner' as the central word -- 
then it might make the privacy implications much clearer also. She 
also owns what can be done with it, to at least some distance from
