Ability for a User to only see their own tags?

[MCKLtech]

I have an application where we want to give the Users the ability to tag their models. For example, a User may have many Student models.

User A would have tags e.g. 'Middle School', 'High School'

User B would have different tags e.g. 'Elementary', 'Pre K'

Is it possible for a user to 'own' those tags such that only they can see them? My guess is that it's possible via the bootHasTags() method but I wanted to check if this is already implemented somewhere.
