Google has temporarily disable a feature added in Android 4.1 Jelly Bean, which aims to lock a downloaded application on a specific terminal to prevent its recovery to piracy. Problem: what DRM is being corrupted on reboot of the device.
To prevent piracy of paid applications, Google has implemented Jelly Bean in a DRM system designed to lock these applications on the smartphone or tablet on which they are downloaded, based on an encryption key specific to the terminal. In this way, it is impossible to copy files for use on another device, even through a backup utility. Functionality development follows criticism leveled at Android, many developers considered previously as an OS easy to hack. The problem is that this leads to new security bugs for some users, who simply can no longer access their applications after restarting their terminals. The Register explains that the problem seems to be in the startup code of Android 4.1, which corrupts encrypted applications during a reboot of the unit, following a termination or a reboot. To overcome the problem, users had to uninstall and reinstall the applications each time. Google, for now, disabled encryption paid applications, which currently settle on Jelly Bean without DRM. The firm will offer no doubt a fix in its next update of Android 4.1.
