Trusted Identifier

Full Title or Meme

A Trusted Identifier is deployed by Entities that wish to be known on the internet for who they are in the real world.

As a part of having a Trusted Identity in Cyberspace a series of Framework Profiles have been created to allow digital Entities to give users a statement about the policies that they support.

See the wiki page on Trusted Location for a list of the ways that a URL can be spoof to see why it is a bad idea to expect users to get a Trusted Identifier from a URL.
EV Certs were introduced to give user's good knowledge of who was behind a web site. They didn't work out as planned as shown on the EV Cert wiki page.

Every real world Entity, be it a legal Entity or a legal name, like a Brand will have one place on the web for making an Identity statement.
That Identity statement MUST be accessed by a URL at a well-known location in a relevant domain.
That Identity statement MAY be accessed at multiple locations that are locale specific for language or other purposes.
That Entity will have a standard URN of the form TID:framework:LUID, where the framework will represent a set of rules that the Entity agrees to follow in all of its online transactions.
