Detecting over-claim permissions and recognising dangerous permission in Android apps

Android's security is one of the hot research topics in the current days. This is mainly due to the leakage of user's privacy information from third-party apps on mobile. Even after the permission model defined by Android we all are witnessing leakage of our critical information. This is mainly due to: 1) the permission model is proportionally coarse granular; 2) insufficient knowledge of user makes him approve over-claim permission mistakenly. Henceforth this paper focuses on recognising dangerous over-claim permission. This starts with describing the permission model, over-claim permission, and some of the dangerous over-claim permission. This paper specifically proposes an algorithm to detect the signature of dangerous permission incorporated during the upgrading version of third-party software.
