After the launch of google Profiles ,now offers a verification features for all its profiles in order to create a web of trust.This reminds me of key signing parties ( i do participated like that in ILUG-D). In a simple words a web of trust is a concept used in PGP, GnuPG, and other OpenPGP-compatible systems to establish the authenticity of the binding between a public key and a user.

Note:This is similar to Knol sites and is simple web based verification which aims to increase the credibility and trustworthiness in the eyes of the other readers. as on Nov 5, this experimental (beta) service is only available for US accounts.

About Verification badge : Google says “Profiles will display a ‘verified name’ badge, if the user has verified their name through Knol. Any user can go through Knol’s interface to obtain the verified badge,”.So if you dont have the verification badge don get panic,just logon to Google? Knol site and follow the verification process

Example of Knol Verification, where people can create their own Web pages to inform others about various subjects.
