Identification vs authentication

On the one hand, we have the assertion that I am a certain person. That is ‘identification’. It is the specific process of attaching an identity of a presence - either a physical presence, or in the context of our current enquiry, a virtual presence. And on the other hand we have the verification (or authentication [jan.]) - the means of proof that what I say is true, that there is sufficient evidence for my claim.
