Privacy Information Security Classification and Comparison between the Westerner and Chinese

A lot of privacy protection technologies have been proposed, but most of them are independent and aim at protecting a specific piece privacy. To minimize the damage and influence of the privacy disclosure, the important and sensitive privacy should be prior preserved if all privacy cannot be preserved. This paper proposes Privacy Information Security Classification (PISC) model, which classifies the privacy into four classifications by the security level. Google and Baidu are taken as the research platform to collect the English data and Chinese data. We comprised the privacy classification results by Google and Baidu data. We also define four security goals for the four classifications.
