On the Internet today, account registration is nearly always a requirement to interact with any website in a meaning-ful way. Each digital identity a user creates is a new and completely disjoint identity from all other existing digital identities of the user. These traditional identities, Identity 1.0 identities, are site-centric and centralized. Alternatively, Identity 2.0 identity solutions are completely decentralized and user-centric. This paper presents four different examples of user in-teraction using Identity 2.0 based solutions that weren’t possible within a traditional identity framework: greylist-ing, identity multiplexing, user-centric privacy, and site pre-registration. To understand the examples further, two ap-plications using aspects of the examples provided were de-veloped and deployed on the Internet for public use. More-over, a third prototype was developed to further understand how users interact within an Identity 2.0 based Internet. Through the study of server logs and informal user studies, two key observations were observed regarding general user patterns of users authenticating themselves within a new identity framework.
