Abstract

Aiming at the quantification of data privacy and data utility in privacy protection, based on the basic principles of metric space and norm, this paper proposed a privacy and data utility metric model. First, it gave the data numerical processing method. And converted the data into a matrix for calculation. Secondly, it introduced a privacy preference function to measure the change of sensitive attributes over time. Then, it analyzed the privacy protection model and quantified the data changes generated by the privacy protection technology. Finally, this paper built a metric space, and gave privacy amount, data utility and privacy protection calculations. Simulation experiments show that the established metric model can effectively reflect the amount of private information.
