摘要： 现有Android移动操作系统不支持用户自由分配已安装的应用权限。为解决该问题，提出一种细粒度的Android应用权限管理模型。该模型在保证系统安全性的前提下，对现有Android应用权限机制的框架层和应用层进行修改和扩展，使用户可以通过GUI界面按需分配系统中已安装的应用权限。实验结果表明，该模型能满足用户的Android应用权限管理需求，并且系统性能损失较小。

Abstract: As existing Android system does not support users to customize the permissions of applications in it, this paper extends the existing Android application permission management mechanism, and proposes a fine-grained Android application permission management model compared to the existing application permission management ability. It retains the existing Android security mechanism, and users can freely customize the permissions of applications that are installed in it through the friendly GUI. Experimental results show that the model can provide users a practical and fine-grained Android application permissions management function, and it has less loss of the system performance.
