Abstract
In one embodiment the present invention includes a computer-implemented method for a mobile device. An application security status is detected. When the application security status is active an application passcode is required to access functionality of a mobile application operating on the mobile device. A first encryption of data associated with the mobile application is performed, where the first encryption uses a first encryption key when the application security status is active, and the first encryption uses a second encryption key when the application security status is not active. A mobile device passcode status is detected. When the mobile device passcode status is active a mobile device passcode is required to access functionality of the mobile computing device. A second encryption of the data is performed when the mobile device passcode status is active, where the second encryption uses a third encryption key.
