doctor to delegate the view/access rights of their medical record to some other

7. Synchronization: This module provides real-time synchronization of CSC's
accounts across multiple Cloud servers. During the CSC's provisioning phase
at CSP1 Cloud administrators asks for CSC's consent regarding whether or not
they want to synchronize their account information on CSP2. Based on their
privacy preferences this module is invoked to perform the synchronization of
CSC's account information. The prime objective of credentials synchronization
is to ensure that each Cloud IDMS holds identical information. In an Inter-
Cloud environment, synchronization is critical to be ensured, otherwise in case
of fail-over, out-of-sync data causes many problems.

8. Self-Service: Self-service module allows the user to update his account infor-
mation such as e-mail address, password, postal address etc. only through the
self-service module. In addition, this module is responsible for making the same
and consistent change across multiple Cloud servers to ensure synchronized and
consistent user information. It facilitates the CSCs by offering them with firm
control over the sharing of their sensitive identity credentials by taking their
consent prior to each credential exchange. However, sensitive information such
as role and other unique identification information that may effect system secu-
rity is not allowed to be modified.

3.1 Workflow of Secure IDMS for Federated Cloud Environment

The basic work-flow of CSC1's registration at the Secure Identity Management Sys-
tem for Federated Cloud Environment is presented in Figure 2. A brief description
for each step is also presented below,
