Data Clean-up Algorithms

Unlike most software providing the confidentiality of PC and Internet activity,
Acronis PrivacyExpert not only deletes Windows sections (files, folders,
registry components, etc.) it also performs a thorough low-level clean-up of
hard disk sectors containing Windows components selected for cleaning.
Trace Windows data and files are cleaned with the help of integrated data
destruction algorithms. Acronis PrivacyExpert provides the user with eight
algorithms. Five of the algorithms meet national data destruction standards:
(1) American: DoD 5220.22-M,
(2) American: NAVSO P-5239-26 (RLL),
(3) American: NAVSO P-5239-26 (MFM),
(4) German: VSITR,
(5) Russian: Russian Standard, GOST P50739-95.
Besides algorithms that meet these national standards, Acronis PrivacyExpert
provides two far more powerful pre-defined algorithms offered by top
information security specialists:
(6) Peter Gutmann's algorithm;
(7) Bruce Schneier's algorithm.
After using the most powerful clean-up algorithms of Acronis PrivacyExpert,
the disk data can in no way be recovered by any modern methods
including the most powerful magnetic microscopy!
The user is also provided with a simple, but fast algorithm to use in less
important situations:
(8) Fast.
The algorithm operation is baseb on multiple rewriting of hard disk sectors containing
user data with chains of logical 0 and 1. As a result previously written data is
replaced by newer random data. For more information on the algorithms see
Appendix A «Hard Disk Wiping algorithms». There you will also find information on
the number of hard disk passes, provided by each algorithm, and numeric chains
written in the process (see A.2 «Algorithms Used by Acronis PrivacyExpert »).
