Digital identity management Digital identity management (IdM
for short) IDM is a term related to how humans are are
authenticated and Authorized across computer networks. It covers
issues such as how users are given an identity, the protection of
that identity, and the technologies supporting that protection
(e.g., network protocols, digital certificates, passwords,
etc.).
Slide 5
Digital identity management
Slide 6
Identity management can involve three perspectives: 1.Creation,
management and deletion of identities 2. The user access (log-on)
paradigm 3. The service paradigm
Slide 7

Introduction Method Conclusion
Slide 8
Introduction Digital identity management services are crucial
in cloud computing infrastructures to authenticate users and to
support flexible access control to services, based on user identity
Properties and past interaction histories. Such services should
preserve the privacy of users. EX: identity verification
Slide 9
Introduction Users have typically to establish their identity
each time they use a new cloud service, usually by filling out an
online form and providing sensitive personal information (e.g.,
name, home address, credit card number, phone number, etc.). This
leaves a trail of personal information that, if not properly
protected, may be misused. Solution: digital identity management
systems

Method Assumes an IdM system that include several entities:
Identity Providers(IdPs) Cloud Service Providers (CSPs) Registrars
users

Method Assume that a user Alice submits a request to her
Hospital Web portal to access her test results. Alice (user) 1
