The Gutmann method is an algorithm for securely erasing the contents of computer hard disk drives, such as files.Devised by Peter Gutmann and Colin Plumb and presented in the paper Secure Deletion of Data from Magnetic and Solid-State Memory in July 1996, it involved writing a series of 35 patterns over the region to be erased.
Eraser securely erases data by overwriting it such that the data is irrecoverable. [1] It supports a variety of data destruction standards, including British HMG IS5 (Infosec Standard 5), American DoD 5220.22-M , and the Gutmann method which features a 35-pass overwrite.
[24] It recommends cryptographic erase as a more general mechanism. According to the University of California, San Diego Center for Magnetic Recording Research's (now its Center for Memory and Recording Research) "Tutorial on Disk Drive Data Sanitization" (p. 8): "Secure erase does a single on-track erasure of the data on the disk drive. The U ...

In computer security, proof of secure erasure (PoSE) or proof of erasure [1] is a remote attestation [2] protocol, by which an embedded device proves to a verifying party, that it has just erased (overwritten) all its writable memory. The purpose is to make sure that no malware remains in the device. After that typically a new software is ...
