Additionally, by importing and improving the repackaging features, this proposed scheme reduces the potential risks of applications and achieves the goal of the dynamic monitoring of permissions. Finally, a comprehensive evaluation, including efficiency analysis and detection evaluation with 1 000 malwares, whose overall average success rate is about 96%, shows the feasibility and univer- sality of the proposed scheme.展开更多
