Security system with proximity sensing for an electronic device
DCFirst Claim
1. A controller for a security system which protects against unauthorized use of an electronic device comprising:
- a control unit which receives a proximity input indicative of proximity of an individual to said electronic device, said control unit comprising,arming means, responsive to said proximity input and to a timer input, for arming said security system a first changeable amount of time after said proximity input indicates cessation of activity at said electronic device; and
disarming means, responsive to said proximity input and to said timer input, for engaging an alarm, when said security system is armed, a second changeable amount of time after said proximity input indicates activity at said electronic device, if said security system is not disarmed within said second changeable amount of time; and
a command unit which causes removal of information from a visual display of said electronic device upon arming of said security system.

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. The security system can include audio and video input devices to capture and store audio and video information while the system is armed and/or while a security violation is occurring. In certain embodiments, the security system also performs usage tracking of the electronic device.
