The major concerns for most cloud implementers particularly in the health care industry have remained data security
and privacy. A prominent and major threat that constitutes a hurdle for practitioners within the health industry from exploiting and

various cloud providers, hacking to comprise the cloud platform and theft of vital patients’ health data.An overview of the
diverse issues relating to health data privacy and overall security in the cloud are presented in this technical report. Based on
