Deleting all device data from the device storage space
- all BlackBerry device user data
- any references to your organization’s PIN encryption key
- any references to the device transport key
- if applicable, authentication information (for example, the binding information of the smart card)
- IT policy public key
- if you reset the device to the factory default settings, any references to past hashes of the device password
- record of time that elapsed since the user last turned on the device
- if you reset the device to the factory default settings, the IT policy that is stored on the device
- if a user selects the Include third party applications option or the User Installation Application option on the device, all third-party applications and application data
If you or a user turned on content protection, the device uses a memory-scrub process to overwrite the application storage on the device and built-in media storage. The memory-scrub process complies with United States government requirements for deleting sensitive user data, including US Department of Defense Directive 5220.22-M and NIST Special Publication 800-88.
For BlackBerry® Device Software 5.0 and later, if you configure the Media Card Format on Device Wipe IT policy rule, the device can delete all user data from a media card. By default, the user can choose to delete third-party applications and the user data on the media card when the user permanently deletes all device data.
