Method and system for locking an electronic device
First Claim
1. A method in an electronic device, the method comprising, at the device:
- storing on the electronic device, a temporary automatic lock time value;
receiving, through a user input interface of the device when the device is in a locked state, a challenge response; and
if the challenge response is accepted;
unlocking the device;
if a temporary automatic lock time indicator is received with the challenge response, setting an automatic lock timer of the device to the temporary automatic lock time value based on the temporary automatic lock time indicator;
if the temporary automatic lock time indicator is not received with the challenge response, setting the automatic lock timer of the device to a default value; and
starting the automatic lock timer, the automatic lock timer causing the device to transition to the locked state upon expiry,wherein the temporary automatic lock time value has a one-time use lifespan and the automatic lock timer resets to the default value after one-time use of the temporary automatic lock time value.

Abstract
A method and a system for locking an electronic device are provided. In one aspect, a method in an electronic device is provided comprising the steps of receiving, through a user input interface of the device when the device is in a locked state, a challenge response and a temporary automatic lock time indicator, and if the challenge response is accepted, unlocking the device, setting an automatic lock timer of the device to a temporary lock time value, and starting the automatic lock timer. In another aspect, an electronic device is provided for implementing the above method. According to another aspect, a locking mechanism is provided that utilizes information on an environment of the electronic device. According to another aspect, a stimulus based locking mechanism is provided that employs a different lock time after the device has issued a stimulus in response to an event on the device.
