Abstract
In recent years, backup and restore is a common topic in data storage. However,
there’s hardly anybody mention about safe data deletion. Common data
destruction methodology requires the wipe operation to fill the disk with
zeros, then with random data, and then with zeros again. Three passes are
normally sufficient for ordinary home users. On the down side, such algorithms
will take many hours to delete a 2TB hard disk. Although current Linux utility
tools gives most users more than enough security and data protections, we had
developed a cross-platform standalone application that could expunge all
confidential data stored in flash drive or hard disk. The data shredding
software is written in Python, and it could overwrite existing data using
user-defined wipe algorithm. This software project also explores the technical
approaches to digital data destruction using various methodologies defined in
different standards, which includes a selection of military-grade procedures
proposed
by information security specialists. The application operates with no
limitations to the capacity of the storage media connected to the computer
system, it can rapidly and securely erase any magnetic mediums, optical disks
or solid-state memories found in the computer or embedded system. Not only does
the software comply with the IEEE T10/T13 specifications, it also binds to the
number of connectivity limited by the SAS/SATA buses.
The paper is very interesting.
Funny though I found it very hard to find a name of the application
developed -- I presume it is the successor of CBL Data Shredder -- or if
it is foss or proprietary package?
Does the application have a project page?
