Identity Management systems have been designed to deal with the authentication and authorization process. They enable Single Sign-On, where a user can make use of an unique account to access different services, and preserve users’ privacy, maintaining users’ attributes on reliable providers.

In the same way, they do not inform the users about how their personal information will be dealt once released.
