1 Introduction
To meet the needs for higher levels of print and imaging security, Hewlett-Packard created HP Secure Erase technology for Imaging and Printing. This capability allows the adm inistrator to select how data is erased from storage devices, including print, scan, fax, and copy jobs. Several levels of erase security are provided. The capability is provided as a standard feature on supported HP multifunction peripherals (MFPs), digital copiers, and printers when used with HP’s Web Jetadmin (available separately).
HP Secure Erase technology provides a choice of three different modes of erase security, each of which can be configured by an administrator and may be protected from unauthorized changes with a password. The three erase security modes are:
- Secure Sanitizing Erase mode: Conforms to the U.S. Department of Defense 5220-22.M specification for deleting magnetically stored data. Secure Sanitizing Erase uses multiple data overwrites to eliminate trace magnetic data and also prevents subsequent analysis of the hard disk drive’s physical platters for the retrieval of data. For an explanation of the erase algorithm implemented, see Section 4, Specifications.
- Secure Fast Erase mode: This mode completes the erasure faster than Secure Sanitize mode. Secure Fast Erase mode overwrites the existing data once, and prevents software-based “undelete” operations on the data.
- Non-secure Fast Erase mode: The quickest of the three erasing modes, , Non-secure Fast Erase mode marks the print job data as deleted, and allows the MFP’s operating system to reclaim and subsequently overwrite the data when needed.
