Optimization Scheme of Access Permission Mechanism Based on Android Platform

To improve the problem of the security of Android access permission mechanism,this paper proposes an optimization scheme for access permission security based on Android platform.It divides the Android permission into four categories,acquires categories of different permission combination,quantifies the permission combination security threat values and takes fact that free applications are more likely for malicious applications than paid applications into consideration,for judging application security threat level by application access permission security threat value.Experimental results show that the permission access security mechanism can effectively detect security threat level of applications,judge the degree of application security threat more accurately and achieve the goal of enhancing the security of Android access control.
