Evolutionary game analysis on permission request policy of service providers
Junlin Jin, Ayong Ye, Yang Zhi-jiang, Li Wen Xu · 2018
In view of the problem of over-requesting permissions in the current smartphone terminal, it is great significant to research the factors of the service providers to select the permission request policy. In this paper, we assume that providers are bounded rational and obtain the payoff matrix based on the two groups of providers with different request policies, which are the “Over-request Permissions” and “Request basic permissions". Then we establish an evolutionary game model for privacy protection between the two groups and find out the stability policy of the model. Initial results demonstrate that whether the provider adopts the “Request basic permissions” policy depends on four factors, which are revenue increase ratio, credit loss, users churn cost and self-attractiveness when over-requesting permissions. And the establishment of privacy alarm mechanism not only can improve the users' privacy awareness, but also increase the users churn cost when providers over-requesting permissions.
