Encrypting/Decrypting Data
If your i.roc x20 Pocket PC has been off for longer than the time you
selected during setup, your data is encrypted. When you turn the
device on, you are prompted to authenticate using your fingerprint,
PIN, and/or password. After successful authentication, your data is
decrypted. This may take a few moments depending on the amount of
data you chose to have encrypted. However, encryption runs in the
background, and you can perform other tasks on your i.roc x20 Pocket
PC during this time.
You can monitor the decryption process in two ways:
If you selected Display encryption status on the Encryption
Settings screen during setup, the ecom ProtectTools window
displays the decryption status.
If you choose not to display this status, the
encryption/decryption process proceeds in the background,
allowing you to use your Pocket PC for other purposes.
In either case, a blue lock icon appears in the Taskbar at the
bottom of the Today screen during decryption. When the icon
disappears, decryption is complete. Typically the Pocket PC
responds more slowly during the encryption/decryption
process.
