An anonymous reader writes "VeriSign and NetMesh are making the case for OpenID, the grass-roots, decentralized digital identity system already supported by LiveJournal, Six Apart, Technorati, VeriSign and many startups, reportedly growing 5% every single week. They say OpenID 'is fundamentally different from other identity technologies' because it is a 'fully decentralized system' and has a 'much lighter cost structure' than any alternative, like Microsoft Passport, CardSpace or Liberty Alliance. Time to remove username and password from your site and add OpenID libraries instead, so visitors can authenticate with their blog URL?" From the article: "If tomorrow, for example, you decide you don't like the Diffie-Hellman cryptographic key exchange at the root of OpenID authentication, you can develop your own way of authenticating, and deploy it within the OpenID framework. If you have an idea for a new identity-related service that nobody else ever thought of, you can deploy it into the OpenID framework as soon as your code is ready. This radical decentralization on all levels of the stack, both technically and organizationally, is a very strong catalyst for attracting innovators and their innovations. This makes OpenID a superior choice for identity-related innovation."
