Role-And Relationship-Based Identity Management for Privacy-Enhanced E-Learning

From a privacy point of view, Identity Management (IM) is primarily concerned with the presentation of oneself, and therefore, can provide users discretionary control over contextual representations of projections of their personal identity. In Role- and Relationship-based Identity Management (RRIM), role and relationship are used as two means of defining a context of representation. A role-based identity offers a common identity for all the users who take on a particular role, while a relationship-based identity allows a user to disclose limited information to another person appropriate for a particular mutual relationship.
