In this paper we have tried to classify apps on the basis of the set of permissions requested so that the user can judge which apps are safe to install and which apps are not. The major contributions of this paper include: (1) Defining a GP-PP classification model for android apps based on the permissions requested by the apps (2) Testing and validation of the proposed model.
