Hints Toward a Solution
Now that we understand how today??™s security schemas work
and how they evolved to their current state, we realize the reasons
why they fall short in providing a common identity layer
for the entire Internet. It is time to put into practice the lessons
learned and devise a long-term solution, ?¬?nally immune from
the errors and shortcomings that af?¬‚ict today??™s patchwork of
partial solutions.
The section ???AWorld Without a Center??? stresses the reasons
why a universal identity layer didn??™t spontaneously emerge to
date and highlights that a truly sustainable solution must address
the needs of all the disparate parties that have an interest in the
Internet.
The section ???The Seven Laws of Identity??? describes the choral
effort that the industry poured into determining the mandatory
requirements that must be met by any acceptable solution to the
online identity problem. The seven laws of identities are a compact
formulation of those ?¬?ndings.
