The measures we previously described are rather an example of
blind credentials: Demonstrating knowledge of the computer
password or the product serial number states my right to access
the resources, but it does not really say anything about who I
am. In a book about identity, it ought to make a difference!
When computers began being organized in local networks, the
music changed. The entire point of connecting computers is
communicating and sharing resources. As a consequence, the
control migrates from a group of individuals with complete
dominance over their machines to a central governance that
establishes what is shared and who can access what. The keyword
in the former sentence is who.Whereas before blind credentials
were required for preventing unauthorized access to the
user??™s own resources, now that sharing becomes the norm as the
concept of authentication arises. The blind credentials system
maintained some grip here and there, like for protecting
archived ?¬?les, but the presence of a shared network promoted
?¬?ner methods of access control such as authorization. Now that
all accesses were mediated by the network infrastructure, there
was no need of remembering a password for every resource.
