Abstract: The Internet was built without a way to know who and what you are connecting to. This limits what we can do with it and exposes us to growing dangers. If we do nothing, we will face rapidly proliferating episodes of theft and deception that
will cumulatively erode public trust in the Internet. [Kim Cameron, identityblog]
