Abstract

A security system includes a proximity sensor to protect against unauthorized access to an electronic device. The security system is armed upon an input from the proximity sensor indicating departure of an authorized user from the vicinity of the electronic device. The security system provides commands to the electronic device as well as other devices coupled to the electronic device to sound an alarm in event of a security violation, clear a display screen of the electronic device or take other security measures to prevent unauthorized use of or access to information contained in the electronic device.
