Subject: Re: Authentication vs identification

Basically:

Authentification is verifying that an user is really the one she's
pretending to be (i.e. by asking for a password).

Identification is trying to put an identity on someone, like her name is
Alice Smith from London (or less precisely by tracking her across websites).
