Abstract: A method for managing permission information of an application in a mobile terminal includes detecting a reference event associated the application, determining a type of the reference event, determining permission information of the application, determining whether to execute an operation of the application based on the permission information, and storing operation performance information related to the operation of the application in a database. A terminal includes an application layer to detect an event associated with a change in permission information of a first application and a second application, and a framework layer to determine whether permission information of the first application is changed with respect to the second application, to determine an event type associated with the change in the permission information, to determine permission information of the first application and the second application, and to determine whether to execute a security program.
