For the time

being, you can just substitute the occurrences of the word in the
de?¬?nition with the same ???somebody or something??? we used in
the section ???Claim.???
Remember the discussion about the difference between credentials
and digital identity in section ???HTTPS, Authentication, and
Digital Identity??? from Chapter 1? The airline example should
have provided an intuitive idea of what we mean by identity in
this context. Now that we have a de?¬?nition, we can re?¬?ne the
concept a bit further.
One thing you might notice from the de?¬?nition is that an identity
is made up of claims all coming from the same source; given
the fact that claims may or may not actually apply, what you
know about that source may in?¬‚uence what you believe to be
true for the entire identity as opposed to considering claims one
by one. There will be more ( muchmore) about this later in the
section.
Another interesting thing you may notice from that de?¬?nition is
that an identity can be self-asserted. It is perfectly legitimate for
somebody to make claims about himself. This actually happens
all the time on today??™s Internet. When you sign up for an
Internet service and you are asked to ?¬?ll in a pro?¬?le, you are
making claims about yourself.
