Abstract

Described here is a method by which shredders can have a specified delay time between the time a data or device object is shredded and the time it becomes non-recoverable. When an object is shredded it will disappear from the container in which it resides. The shredder takes the object from where it resides and places it into a hidden area. All of a devices' property and instance information is kept in the hidden area allowing the device to recreate itself exactly as it was prior to the discard. All of a data object's property information is also kept allowing the object to be recreated as it was prior to deletion. The shredder will monitor the date and time for all recoverable objects, deleting them when the delay expires. Until expiration of the delay, a discarded data or device object can be recovered.

Delayed Destruction of Data and Device Objects Through a Shredder

      Described here is a method by which shredders can have a
specified delay time between the time a data or device object is
shredded and the time it becomes non-recoverable. When an object is
shredded it will disappear from the container in which it resides.
The shredder takes the object from where it resides and places it
into a hidden area.  All of a devices' property and instance
information is kept in the hidden area allowing the device to
recreate itself exactly as it was prior to the discard.  All of a
data object's property information is also kept allowing the object
to be recreated as it was prior to deletion.  The shredder will
monitor the date and time for all recoverable objects, deleting them
when the delay expires.  Until expiration of the delay, a discarded
data or device object can be recovered.

      When creating a shredder, the user specifies within properties
the desired delay time.  A new properties dialog named Delay will be
used to allow users to specify the desired amount.  Three spin
buttons will be placed on the dialog, one each for days, hours and
minutes. The template values will initially be set to zero for all
fields.

      To work with recoverable data and device objects, a user will
perform an open action on the shredder.  The shredder then opens
itself just as a container, displaying all the discarded objects not
having had their delay time expire.  I...
