The problem to be solved is one of proving ownership of a device. For example, an ipad left at a train station or on a flight by accident, can be found and handed in to a lost property office. The owner of the device subsequently telephones the lost property office and has to prove ownership of the device. Merely stating that the lost device is an ipad is not sufficient. It is usually necessary to divulge the passcode of the device to prove ownership. The problem then is that the staff at the lost property office have complete access to the device and any potentially confidential or personal data which may be stored on the device.

    Whilst this disclosure could be applied to any computer or device, the primary use for it would be on portable, and hence easily mislaid, devices such as mobile telephones and tablet computers. Most such devices currently require an access code to be entered before the device can be used. Once the access code is entered, full access to the device is granted so that all applications and data can be used. The current invention is to have a "proof of ownership" passcode on devices
