Abstract

Prior methods provide mechanisms to secure computing systems, e.g., lock the keyboard of a personal system. To lock the keyboard, a user enters a command using the keyboard of the system. Optionally, a timer may be set to lock the keyboard after a user-defined elapsed time of inactivity. Often times, users step away from their office leaving their computing system unattended for longer periods than expected without a convenient way to establish access to their computing system. In addition, not every user sets the locking timer due to the inconvenience of locking and unlocking of their system.

Remote Locking Mechanism using Dual Tone Multiple Frequencies

      Prior methods provide mechanisms to secure computing systems,
e.g., lock the keyboard of a personal system.  To lock the keyboard,
a user enters a command using the keyboard of the system.
Optionally, a timer may be set to lock the keyboard after a
user-defined elapsed time of inactivity.  Often times, users step
away from their office leaving their computing system unattended for
longer periods than expected without a convenient way to establish
access to their computing system.  In addition, not every user sets
the locking timer due to the inconvenience of locking and unlocking
of their system.

      Provided is a telephone software control mechanism that allows
a user to secure a computing system remotely using conventional
telephone lines.  More specifically, a Voice Activated Response
System (VARS) that allows Dual Tone Multiple Frequencies (DTMF) to
control remote applications via a touch tone telephone to lock the
keyboard or ICONs on a desktop of a computing system.

      This mechanism allows users to control a remote locking
application using conventional touch tone telephones to secure a
computing system by signaling the computing system to lock the
keyboard or one or more ICONs on the system desktop.  This invention
consists of a Master Controller that receives the DTMF when a caller
dials in.  An Authentication Service verifies the caller
identification.  An Audio Distribution System (ADS) presents the
caller with an acti...
