coondoggie handed us a link to a Network World article reporting that IBM plans to open source the project 'Identity Mixer'. Developed by a Zurich-based research lab for the company, Identity Mixer is a novel approach to protecting user identities online. The project, which is a piece of XML-based software, uses a type of digital certificate to control who has access to identity information in a web browser. IBM is enthusiastic about widespread adoption of this technology, and so plans to open source the project through the Eclipse Open Source Foundation. The company hopes this tactic will see the software's use in commercial, medical, and governmental settings.
