What are the key differences between OpenID and Information Cards?
OpenID does not require any client software, offers a strong installed base of relying parties and enabled users, and is already popular among user-generated content (blogs, wikis, discussion forums) and other managed content applications (media, sports, news, entertainment, music, product information, etc.)OpenID is developing additional functionality to enhance applicability for commerce and other higher assurance applications.Information Cards leverage client side software that can allow scaling to higher Levels of Assurance, provide additional protection from phishing, and can share third-party verified credentials (e.g., proof of your age, credit rating, employer, etc.) Note that both OpenID and Information Cards can give users the ability to review when, where, and why they have shared personal information, and potentially to correct and/or withdraw it.
