Abstract

Current art provides mechanisms that are cognizant of environmental variances. Infrared or radio frequencies can be used to drive a badge reader and facilitate identification process. Encoded cards can be read by a proximity system to validate and authenticate user authorization. These mechanisms require users to stay within an operating range. Yet, other auto-locking mechanisms lock the user system based on a predefined time interval of inactivity regardless of the presence of users at their workstation.

Remote Locking Mechanism Based on Existential Acknowledgment

      Current art provides mechanisms that are cognizant of
environmental variances.  Infrared or radio frequencies can be used
to drive a badge reader and facilitate identification process.
Encoded cards can be read by a proximity system to validate and
authenticate user authorization.  These mechanisms require users to
stay within an operating range.  Yet, other auto-locking mechanisms
lock the user system based on a predefined time interval of
inactivity regardless of the presence of users at their workstation.

      This method describes an auto-locking mechanism based on
proximity characteristics of an existential acknowledgment.  This
consists of a system which includes a set of infrared proximity
controllers that passively monitor the location of electronic ID
badge wearer and only activate the system locking mechanism if users
stay away from their system for a predefined time interval in
combination with a specified distance.  More specifically, it
consists of a Supervisory Controller which resides in the users
system that interfaces with the infrared remote control
encoder/decoder controllers.  An encoder, e.g., an infrared ID badge,
carried by users sends signals to a proximity controller decoder,
e.g, an infrared recognition circuity.  The proximity controller
decoders can be installed throughout an establishment which create an
Infrared Link network.  The encoders serve as gateways responsible to
direct infrared codes to the Supervisory Controller.  The Supervisory
Controller can receive unique signals from a encoder/decoder...
