I do distinguish between authentication and validation, where it seems
that authentication is a subset of the much broader term validation, just
not the narrow 'identity centric' subset that you are defining.

It seems to me that 1 is a perfect definition for 'identification', not
for authentication.

  validation > authentication (3) > identification (1)

(2 was just an other partially overlapping subset of 3, so lets further
ignore my 2 and focus on Alan's 3 vs 1)

Where you feel that I am using authentication where the broader term
validation should be used, I feel that you are using authentication where
the more narrow term identification would be in place.
