Full Disk Encryption
Android provides a mechanism to protect user data.
- Other Data
Currently, Android supports encryption of user data and gives the option of providing software or hardware based encryption solutions. There are trade-offs between the two that are outlined below:
Software-based vs. Hardware-based Disk Encryption
Software-based disk encryption has several shortcomings.
- All encryption operations occur in the software = power intensive
- It stores the encryption key in the RAM, which can be dumped and searched = less secure
Hardware-based disk encryption provides certain benefits.
- It utilizes hardware-based encryption blocks for computation intensive encryption operations = saves power & time
- Hardware-based disk encryption stores encryption keys securely = increased security
ODG has implemented hardware-based accelerated disk encryption as a result. This capability has been included in software release v3.5.17
- For Glasses shipped with v3.5.17, starting in August 2016, the user-data partition was formatted to enable this feature in the factory.
- Glasses shipped before this time with release 3.4.5 or 3.1.12 do not have the feature, and even after an over the air (OTA) System Update.
- To enable this functionality when updating from a previous software version you must first do a factory reset of the glasses, which will re-partition the user-data.

Prior to doing a Factory Reset you must back up all user data and files. Existing user data and files will be deleted when conducting the Factory Reset.
**Note that you must define a screen lock PIN before you will be allowed to turn on disk encryption.**
