Background: The most important question about the application and development of
cloud computing is the privacy risk, as it has become the key factor for users in selecting cloud services.
In order to have a better understanding of the privacy risk, resolve or make it controllable in
an acceptable range, risk assessment is very necessary. However, specialized research on the assessment
has not yet been found.
Methods: This paper has used Information Entropy Theory and Fuzzy Set Theory to evaluate cloud
computing privacy security risk.
Results: This paper analyzes the research actuality of cloud computing privacy security and combs a
number of cloud computing privacy security risks on the basis of digging deep into the characteristics
of cloud computing and previous studies, thus further establishing an evaluation index system
for privacy risk initiatively. Then, the entropy weight theory and fuzzy set theory are used to establish
a fusion of multiple factors of the assessment model.
Conclusion: A practical case is given to prove the feasibility, rationality and effectiveness of the
