David Recordon works for VeriSign within their Advanced Products & Research group with a current focus on digital identity technologies. In 2005, Recordon worked with Brad Fitzpatrick developing OpenID, a decentralized single-sign-on protocol, and has taken on an instrumental role in shaping Yadis, which is designed to ease service discovery for personal digital identity technologies. Through his role at VeriSign, he has continued working with the community to evolve OpenID into a framework that provides services other than just authentication. While teaching himself PHP as a sophomore in high school, Recordon became involved in an open source message board project where he volunteered his time advising a team of over forty people worldwide. Pursuing this interest lead him to co-found a company which hosts message boards for tens of thousands of people. While still an open source hacker at heart, his role at VeriSign allows him to pursue his interests beyond just coding.
