A Privacy-Enhanced User-Centric Identity and Access Management Based on Notary
Identity and Access Management (IAM) systems aim to control of users' attributes for authentication, authorization and accountability processes. Public Key Certificates (PKCs), like the X.509 standard, use asymmetric key pairs to support digital signatures, authentication processes and to increase the trust in the communication. Nevertheless, the PKC does not concern itself with the management of users' attributes and their privacy to be used as an IAM system. The authors present a privacy-enhanced identity and access management architecture, addressing the user's management of their attributes and the privacy.
