Game Analysis of User Privacy Protection Based on Mobile Application Category
At present,mobile app excessively collects personal information,which leads to frequent privacy problems.However,with the principle of"informed consent"and"minimum information"clarified in Chi-na's legislation,the dominance of personal information gradually returns to users.Therefore,in order to better protect the security of personal information,users need to make clear the differences in privacy pref-erences when using different apps;and app service providers also need to make reasonable information se-curity investment decisions according to users'preferences.In order to balance the user privacy security and the information security input of service providers,this paper designs a questionnaire to obtain the user privacy preference,and classifies the user privacy preference categories by hierarchical clustering.Then,based on the static game model,we give the utility function of the participants and calculate the equilibri-um points of different user categories respectively,so as to protect the users safely and efficiently.
