Etymology: "Unshared" is a plain formation: the negating prefix "un-" attached to the adjective "shared". The prefix has a long pedigree. It descends from a Proto-Indo-European negative particle, passed through Proto-Germanic and Old English, and was used productively in English from Old English onward, which is why it can be attached freely to participles and adjectives like this one. "Shared" itself comes from the verb "share", so "unshared" literally means "not shared" or "not having been divided up." Its sense of standing alone, undistributed, or belonging to one party only grows naturally from that negation, rather than from any special history of its own.
