Data Deletion

ProtectStar™, Inc. has developed one very efficient deletion algorithms, both for its own ProtectStar™ products and for third party companies. This deletion algorithm that has been specially developed and protected under the name of ProtectStar™ Secure Deletion Algorithm©, offers users the highest security on the market.

The algorithm is based on various recognized high security processes that build up on each other.

 

Details:

In a first step, all the data is over-written with random values in two passes, and then twice with their complement. To finish off, there is one further pass with random values.

In a second step, all the data will then be overwritten with three passes of the Department of Defense (DoD) 5220.22-M (E) Standards, and then with a random value, and finally once again through DoD 5220.22-M (E)
The method used here in the second step, with a total of seven passes (DoD 5220.22-M ECE), is based on the “National Industrial Security Program Operating Manual”, NISPOM, of the DoD dated January 1995.

In the last pass, the data will be overwritten by the thirty five passes defined by Peter Gutmann and then by three further passes defined by ProtectStar™, Inc.

In total, the “ProtectStar™ Secure Deletion Algorithm©” consists of 50 passes, which guarantees the maximum security for the deletion of data.
