Online identity and identity management infrastructures

A problem facing anyone who hopes to build a positive online reputation is that reputations are site-specific; for example, one's reputation on eBay cannot be transferred to Slashdot.

Multiple proposals have been made[citation needed] to build an identity management infrastructure into the Web protocols. All of them require an effective public key infrastructure so that the identity of two separate manifestations of an online identity (say, one on Wikipedia and another on Twitter) are probably one and the same.

OpenID, an open, decentralized standard for authenticating users is used for access control, allowing users to log on to different services with the same digital identity. These services must allow and implement OpenID.
