Kingdom: Encapsulation

Encapsulation is about drawing strong boundaries. In a web browser that might mean ensuring that your mobile code cannot be abused by other mobile code. On the server it might mean differentiation between validated data and unvalidated data, between one user's data and another's, or between data users are allowed to see and data that they are not.

Insecure Storage: Android Backup Storage

Abstract
The program uses Android's backup service to save persistent application data to a remote cloud storage.
Explanation
Android's backup service allows the application to save persistent data to a remote cloud storage in order to provide a restore point for the application data in the future.

Android applications can be configured with this backup service by setting the allowBackup attribute to true (the default value) and defining the backupAgent attribute on the <application> tag.

Android however, does not guarantee the security of your data while using backup, as the cloud storage and transport vary from device to device.
