The user of Internet services is overcome with identities. She is seldom able to transfer her
identity from one site to another. The reputation that she gains in one network is useful to
transfer to other networks. Nevertheless, she cannot profit from her constructed reputation,
and she must rebuild her identity and reputation time and again. The actual systems don’t
allow users to decide about the sharing of their attributes related to their identity with other
users. This causes a lack of privacy control. Some solutions propose an advanced social
system that would model the social interaction after the real world.
The solutions must be easy to use and enable users to share credentials among many services
and must be transparent from the end-user perspective.
The principle of modern identity is to separate the acquisition process from the presentation
process. It is the same for the identification process and the authorization process. Moreover,
it provides scalability and privacy. In separating these processes, we can have more control
over our identities.
