Patent ID: 7966483

Claim:
A communication device comprising: storage configured to store information; an output device configured to output the information; a power supply detector configured to detect whether an external source is coupled to the communication device and supplying power to the communication device; detect that the external power source is uncoupled from the communication device and not supplying power to the communication device, detect that an external source is again coupled to the communication device and supplying power to the communication device, and determine an amount of time from when the external power source is uncoupled from the communication device and not supplying power to the communication device to when an external source is again coupled to the communication device and supplying power to the communication device; and a processor configured to determine whether the amount of time determined has reached a threshold, and prohibit the stored information from being output by the output device based on whether the amount of time is determined to have reached the threshold, responsive to the power supply detector detecting that an external source is again coupled to the communication device and supplying power to the communication device.
