Evaluation Mechanism of Privacy Protection on Dynamic Data Targeted at Data Partition

In the multi-tenant cloud computing application environment, the business process can affect the data distribution in the underlying cloud storage. The data redistribution may cause leakage of privacy and then to some extent will affect the effect of data partition privacy protection technology. To address the issue of leakage of privacy resulted from data dynamic change, A kind of dynamic evaluation mechanism of data privacy protection in the cloud environments is proposed. The dynamic evaluation mechanism can complete the data processing of the through algorithm of dynamic data processing when the data dynamically changes, and then concludes the measure results of privacy leakage with application of dynamic evaluating algorithm. Through analysis, the thesis proves rationality of dynamic evaluation mechanism of privacy protection and verifies its practicability through experiment.
