How do you implement an identity system for comments without needing any sites to integrate with external services? Example of such external commenting systems that provide advance identity and reputation management are Disqus (screenshot), Sezwho (screenshot), Intense Debate (screenshot) and coComment (screenshot) - one problem with such systems is that both sides (i.e the commentators & the sites) have to adopt the same system. One possible solution is to ask the commentator to leave a name, email address and an url to a site with a form like the one shown in this image - such a system doesn't really help in authenticating the identity of the commentator because the name, email and url left by one commentator can easily be obtained and used by an imposter or the information provided is similar enough to be convincing
This site, now referred as COTRD, is the implementation of a possible alternative solution. COTRD is responsible for the authentication of the user's identity. The commentator, representing a site or company, who would like to establish his identity on another site, first logs into this site to post the comment. Once the comment has been posted on COTRD, the user then posts the same comment on the other site with a link back to the comment on this site.
Because only an authenticated user representing a site or company can post on COTRD, if the comment on other sites matches the comment posted on COTRD, that comment must have been made by the authenticated user.
