Abstract
An application is activated with access permission to resources which are granted to unsigned applications. In parallel with the execution of the application, tamper check is performed on the application using a tamper check thread. When access to a resource which is not granted to unsigned applications is requested during the execution of the application before the completion of the tamper check, the application is put in a wait state until the completion of the tamper check. After the application is judged as having been untampered with as a result of the tamper check, the application is further granted access permission to resources that are specified by a permission information file included in the application. If this further-granted access permission includes the access right to the resource, the execution of the application is continued.
