Increasing Security and Privacy in User-centric Identity Management: The IdM Card Approach

In this paper, we describe how security and privacy can be increased in user-centric Identity Management (IdM) by the introduction of a so-called IdM card. This IdM card securely stores and processes identity data of the card owner, an end user. The card represents a trusted device that supports the user in managing its digital identities and also in performing secure and privacy-enhanced service authentication and authorization.
