Toshiba's Wipe technology aims to improve data security and reduce the risk of data leakage associated with document image data stored on copier and printer systems.

Technology giant Toshiba announced Wipe for its Self-Encrypting Drive (SED) models, a technology that allows special security capabilities, such as the ability for sensitive user data to be securely erased when a system is powered down or when an SED HDD is removed from the system. The feature can also be used to erase user data prior to returning a leased system, system disposal or repurposing.

Toshiba said Wipe was created as an enhancement to Toshiba's SED hard disk drives.

Wipe technology may be used to set data invalidation attributes for multiple data ranges, the company noted. Features include data encryption and secure invalidation on power cycle and data encryption and preservation on power cycle. Copier and printer systems vendors can also use the company's Wipe technology to securely invalidate sensitive document image data by automatically erasing the SED's internal encryption key. This feature can be used prior to system disposal or repurposing to ensure that private data never leaves the control of the IT department.

"Many organizations are now realizing the critical importance of maintaining the security of document image data stored within copier and printer systems," a company release said. "Wipe is a technology that can automatically invalidate an HDD security key when its power supply is turned off, instantly making all data in the drive indecipherable."

Toshiba announced its latest 2.5-inch 7,200-rpm SED HDD model in July 2010, to address the increasing need for IT departments to comply with privacy laws and regulations governing data security. Designed to the Trusted Computing Group "Opal" Specification, Toshiba's SED models provide access security and on-board encryption for client systems such as notebook computers.

"In addition to sensitive data stored on client PCs and removable storage devices, many organizations realize that security of 'data at rest' must also extend to document images stored on the hard disk drives within copier and printer systems," the release noted. "Toshiba's Wipe technology provides advanced storage security features to enable systems makers to transparently and automatically secure private data on office copiers, printers and other types of business imaging systems."
