Abstract
An approach is provided for performing a device-level and/or an application-level security check of a device. In the device-level check, a device hash is generated based on a subscriber identity module identifier (SIM ID), a device identifier, the number of secured applications, and the names of the secured applications. A temporary device hash is generated during a booting of the device. If the device hash is determined to not match the temporary device hash, the applications are removed from the device during the booting of the device. In the application-level check, an application hash is generated based on the SIM ID, the device identifier, and the application name. A temporary application hash is generated during a loading of the application. If the application hash is determined to not match the temporary application hash, the application is removed from the device without running the application.
