Enhancement on privacy permission management for Android apps

Now a days everyone is using smartphone devices for personal and official data storage. Smartphone apps are usually not secure and need user permission to access protected system resources. Specifically, the existing Android permission system will check whether the calling app has the right permission to invoke sensitive system APIs. Android OS allows third-party applications. Whenever a user installs any third party application user is having, only limited options at the time of installation. Either user can agree to all terms and conditions and install that application or reject from the installation of applications. Existing approaches failed to provide security to user´s sensitive data from being violated. To protect user´s privacy, there is a need for secure permission management for Android applications. In this paper, to fine-grained the permission management, we have proposed a system which provides a facility to smartphone user´s grant or revoke access to user´s private sensitive data as per user´s choice. Overall Performance of proposed system improves the limitations of existing android permission system shown in detail in terms of results and features in the paper.
