Abstract
A method for controlling access to a computing device which involves detecting, at a key device, one or more wireless devices configured as wireless access points. A handshake operation involving the key device and the computing device is performed wherein the computing device is included among the one or more wireless devices. Wireless signals transmitted by the computing device are received, during a calibration phase, at the key device. During the calibration phase the key device determines an approximate signal strength corresponding to a desired distance between the key device and the computing device. Based upon a received signal strength of other wireless signals transmitted by the computing device, it may be detected that the key device and the computing device are separated by at least the desired distance. If so, the computing device may be electronically locked or user access to it otherwise inhibited.
