Subject: Re: Authentication vs identification

i do not have an issue with your views on auth and ID,
(besides them being a little prolix for my taste)
i want to EMPHASIZE the characteristic difference between the two in 
question. because some of this list's subscribers had claimed (a while 
ago) that there is no difference between auth and ID whatsoever.

> Indeed, your definition would, to the extent that these matter to what people do in practice, further encourage the bad behavior. If you require someone to give you their birthdate, then that becomes authentication by your definition.

no it doesn't.
i did not say "an actor demands anything"
i said the procedure itself REQUIRES (includes with necessity)...
which means without the feature in question the procedure loses its essence.
