Abstract

A methodology is described for presenting a user with a warning signal, prior to locking a computer system, which would allow the computer user to present a unique phrase (voice) or keyboard or mouse interrupt for interrupting a computer lock procedure. The warning signal lead time and form is configurable.

Method of AND Apparatus for Conveniently Resetting Electronic Lock of Computer System

      A methodology is described for presenting a user with a warning
signal, prior to locking a computer system, which would allow the
computer user to present a unique phrase (voice) or keyboard or mouse
interrupt for interrupting a computer lock procedure.  The warning
signal lead time and form is configurable.

      Current computer system lockup techniques for automatic locking
require a keyboard entered password to unlock the system.  Once a
configured time limit has expired, the system begins the locking
sequence, which may coincide with an audible signal or displayed
visual indicating locking is taking place.  Once the notification is
presented, the user must enter a password to unlock the system.  It
is desirable to add an additional signal, as a warning, which
presents itself a configurable amount of time (e.g 10 seconds) prior
to the system actually locking.  The user, if present, would then
have the option to prevent the system from locking by either moving
the mouse, hitting the keyboard or speaking.  This would allow the
lock to be prevented, thereby eliminating the need for the user to
reenter a password.

      This article methodology recognizes the computer user by voice
during the lockup warning procedure.  Upon recognition, the mode for
locking up the system is interrupted and the lockup is reset.  Any
voices which are used to reset the system that are not recognized as
the user of the system will not reset the lock.  This recognition of
voice maintains the same level of security as keying in a password.
A voice print is saved in a library for a user either by taking voice
snapshots from spoken phrases or by invoking a save voice print
function while actively talking to the audio component of a connected
microphone device.  It is recommended a variety of voice prints be
kept in a library for any single person over a period of time to
guarantee a voice match by ensuring a full spectrum of voice prints.
Specifying that only a specific user's voice be used to perform a
reset offers another level of security in u...
