1. A security system for an electronic device comprising, in combination:

sensing means for detecting the proximity of a user to said electronic device, means, responsive to said sensing means for at least partially disabling said electronic device to prevent full use of said electronic device upon detection by said sensing means that said user is no longer in proximity to said device, and a verifier which accepts input about said user to determine if said user is authorized to use said electronic device and which restores full use of said electronic device when disabled upon recognizing said input as an authorized input.

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.

1. A security system for an electronic device comprising, in combination:
- sensing means for detecting the proximity of a user to said electronic device, means, responsive to said sensing means for at least partially disabling said electronic device to prevent full use of said electronic device upon detection by said sensing means that said user is no longer in proximity to said device, and a verifier which accepts input about said user to determine if said user is authorized to use said electronic device and which restores full use of said electronic device when disabled upon recognizing said input as an authorized input.
- View Dependent Claims (2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25)
- - 2. A security system as set forth in claim 1 wherein said sensing means comprises at least one proximity sensor and means for adjusting the sensitivity of said proximity sensor.
  - 3. A security system as set forth in claim 2 wherein said means for adjusting the sensitivity of said proximity sensor automatically performs said adjustment in accordance with a preset schedule.
  - 4. A security system as set forth in claim 2 wherein said means for adjusting said sensitivity of said proximity sensor includes adaptive learning means for varying said sensitivity in response to prior detected conditions affecting said electronic device.
  - 5. A security system as set forth in claim 1 including timing means for establishing a delay duration before electronic device is at least partially disabled after the detection by said proximity detector that said user is no longer in proximity to said device.
  - 6. A security system as set forth in claim 5 including means for adjusting said duration to vary the permissible interval during which said user may be away from said electronic device without causing said device to be at least partially disabled.
  - 7. A security system as set forth in claim 1 further includes means for detecting a potential unauthorized use of said electronic device after said electronic device has been at least partially disabled and means for executing one or more security procedures in response to the detection of a potential unauthorized use.
  - 8. A security system as set forth in claim 7 wherein said security procedures include acquiring information for identifying the person or persons perpetrating said potential unauthorized use of said electronic device.
  - 9. A security system as set forth in claim 7 wherein said means for detecting a potential unauthorized comprises means for detecting an attempt to supply input information to said electronic device when said electronic device is at least partially disabled.
  - 10. A security system as set forth in claim 9 further includes means for delaying the execution of at least one of said security procedures for a predetermined time interval following the detection of an attempt to supply input information during which said verifier accepts input about said user to determine if said user is authorized to use said electronic device.
  - 11. A security system as set forth in claim 7 wherein said means for detecting a potential unauthorized use comprises means for detecting the disconnection of said electronic device from a previously connected instrumentality.
  - 12. A security system as set forth in claim 1 further including means for acquiring a visual image of the person or persons perpetrating said potential unauthorized use of said electronic device.
  - 13. A security system as set forth in claim 1 wherein said security system includes means for identifying said user.
  - 14. A security system as set forth in claim 13 wherein said means for identifying said user includes a camera for acquiring a visual image of said user and means for comparing said image with image identification data to establish the identity of said user.
  - 15. A security system as set forth in claim 13 wherein said means for identifying said user includes a microphone for acquiring sounds spoken by said user and means for comparing said sounds with voice identification data to establish the identity of said user.
  - 16. A security system as set forth in claim 13 wherein said means for identifying said user includes means for acquiring data describing the fingerprint of said user and means for comparing said fingerprint information with fingerprint identification data to establish the identity of said user.
  - 17. A security system as set forth in claim 13 wherein said means for identifying said user includes a detectable device having unique characteristics which accompanies said user and means for detecting said unique characteristics to establish the identity of said user.
  - 18. A security system as set forth in claim 17 including means for acquiring usage information containing the identity of said user and describing and activities performed by said user.
  - 19. A security, system as set forth in claim 17 wherein said usage information includes a description of the subject matter presented to said user by said electronic device.
  - 20. A security system as set forth in claim 17 including means for recording said usage information in a log file for later processing.
  - 21. A security system as set forth in claim 17 including means for transmitting said usage information to a remote location.
  - 22. A security system as set forth in claim 1 wherein said sensing means comprises a plurality of proximity sensors for detecting different kinds of unauthorized activity.
  - 23. A security system as set forth in claim 22 including means for selectively activating individual ones of said proximity sensors in accordance with a programmed schedule.
  - 24. A security system as set forth in claim 1 wherein said electronic device is a computer.
  - 25. A security system as set forth in claim 24 further including means responsive to said sensing means for executing one or more predetermined programs when said sensing means detects that said user is no longer in proximity to said device.
