RIM said it has added features to its BlackBerry Tablet OS 2.0.1 designed to “curb the piracy” of apps for the platform, following previous concern about side-loading by users.

The company said that back-up files are now tied to a BlackBerry ID, which it said prevents users from sharing backup files between devices, while still allowing them to switch handhelds if necessary.

In addition, backup files are now encrypted, which RIM said “not only helps protect user’s data, but also…applications.” The encryption key for the backup file is tied to a BlackBerry ID, meaning each user has a different code for files.

Finally, noting the possibility that users may opt not to update the device OS in order to continue using pirated files, RIM said that developers will be able set OS 2.0.1 as a requirement for new installs, meaning it will be unavailable to users of the less secure platform.
