UEC is an open source Linux based architecture which is included with Ubuntu
server edition [12]. It provides virtualization capability; flexibility and applications
to assist in deploying a cloud within an organization [11]. UEC will aim to solve the
above privacy and security issues by ensuring that there is a reasonable balance
between unrestricted cloud administrators’ competence of fulfilling their duties and
disclosure of only the precisely identified information based on administrators [13].
Furthermore, UEC should be able to limit the system level modifications requisite in
order to make the use of privacy preservation technique trouble free and swift. In
addition, UEC should not sustain any data loss on users’ private information stored
in the cloud database [12].
