Register you device with your contact information. Sign your device with your own contact information and password.
At any time you can add, modify and remove your contact information linked to your device.
Registering your device can help you identifying a stolen or lost device. Give your device a chance to find his owner.

The device ID and the ownership information are stored on aserver under your own password. Even if the device is rebooted the ownership information is not lost. You are the only one who can remove this information once it was stored.

If you find a device and you want to retrieve it to the original owner this is also the application you need.

Good luck!
