What did the Author mean by saying "Bluetooth does not provide native user authentication."

Question

I was reading an article on Bluetooth security (see citation below), and in the introduction the authors writes:

"Bluetooth specifications provide for three basic security services: -

Authentication: verifying the identity of communicating devices based on their Bluetooth device address.

Bluetooth does not provide native user authentication. "

What do they mean by that? I had trouble understanding what they were trying to say by "native user authentication".

Answer 1

This means that if you connect Bluetooth device A to device B then device B can be sure that A is really A, but cannot tell that the user of A is who he or she claims to be. If you need B or the user of B to be certain of the identity of the user of A then you will need an additional layer i.e. one that is not native to Bluetooth.
