Driving a hard bargain for data

05.11.2008
Ongoing research to be published in the International Journal of Liability and Scientific Enquiry suggests that there is a huge amount of sensitive data still on redundant computer hard disks.

These devices are often disposed of or sold into the second-hand market by corporations, organizations, and individuals with the data intact. The report's authors say that this data represents a significant level of risk for commercial sabotage, identity theft, and even political compromise, and suggest that better education is essential to reduce the risk of harm.

It is not well known among computer users that simply deleting a file from the hard disk does not actually remove it from the computer but simply deletes its entry in the index for the hard drive. To remove all traces of a file requires the actual data to be wiped using "digital shredding" software. Such software is readily available and should be run as a high priority by individuals, companies and organizations intending to pass on their legacy computer hardware to third parties.

Andrew Jones, Head of Information Security Research, at British Telecommunications, in Martlesham Heath, UK, working with Glenn Dardick of Longwood University, in Farmville, Virginia, and colleagues Craig Valli, of Edith Cowan University, Western Australia, and Iain Sutherland of the University of Glamorgan, UK, have analyzed data that remained on a number of second hand hard disks that had been obtained on second-hand markets.

"The research revealed that a significant proportion of the disks that were examined still contained considerable amounts of information, much of which would have been of a sensitive nature to the organization or individual that had previously owned the disk," the researchers explain.

The team adds that the percentage of disks that have been effectively wiped had fallen significantly, from 45% to 33%, since the previous year's survey. "With only 33% of working second-hand disks having been effectively wiped, it is reasonable to comment that this is an area where there is significant potential for improvement," they say.

They make several recommendations for improved data security - with regard to hard disks and other storage media, including memory cards, mobile phones, and other devices, and suggest that public awareness campaigns by Government, the media, commerce and/or academia ought to be run to help reduce the risk of sensitive data entering the information black-market.

The 2007 study is being made available in its entirety through the International Journal of Liability and Scientific Enquiry. The team is now completing the 2008 analysis and will announce those results shortly as well. However, the initial results for the 2008 study show that there is still a long way to go regarding the decommissioning of computer hard disk drives. The team expects that the complete 2008 study will be made available for publication by the end of the year.

Im Focus: Making lightweight construction suitable for series production

More and more automobile companies are focusing on body parts made of carbon fiber reinforced plastics (CFRP). However, manufacturing and repair costs must be further reduced in order to make CFRP more economical in use. Together with the Volkswagen AG and five other partners in the project HolQueSt 3D, the Laser Zentrum Hannover e.V. (LZH) has developed laser processes for the automatic trimming, drilling and repair of three-dimensional components.

Automated manufacturing processes are the basis for ultimately establishing the series production of CFRP components. In the project HolQueSt 3D, the LZH has...

Im Focus: Wonder material? Novel nanotube structure strengthens thin films for flexible electronics

Reflecting the structure of composites found in nature and the ancient world, researchers at the University of Illinois at Urbana-Champaign have synthesized thin carbon nanotube (CNT) textiles that exhibit both high electrical conductivity and a level of toughness that is about fifty times higher than copper films, currently used in electronics.

"The structural robustness of thin metal films has significant importance for the reliable operation of smart skin and flexible electronics including...

Im Focus: Deep inside Galaxy M87

The nearby, giant radio galaxy M87 hosts a supermassive black hole (BH) and is well-known for its bright jet dominating the spectrum over ten orders of magnitude in frequency. Due to its proximity, jet prominence, and the large black hole mass, M87 is the best laboratory for investigating the formation, acceleration, and collimation of relativistic jets. A research team led by Silke Britzen from the Max Planck Institute for Radio Astronomy in Bonn, Germany, has found strong indication for turbulent processes connecting the accretion disk and the jet of that galaxy providing insights into the longstanding problem of the origin of astrophysical jets.

Supermassive black holes form some of the most enigmatic phenomena in astrophysics. Their enormous energy output is supposed to be generated by the...

Im Focus: A Quantum Low Pass for Photons

Physicists in Garching observe novel quantum effect that limits the number of emitted photons.

The probability to find a certain number of photons inside a laser pulse usually corresponds to a classical distribution of independent events, the so-called...

Im Focus: Microprocessors based on a layer of just three atoms

Microprocessors based on atomically thin materials hold the promise of the evolution of traditional processors as well as new applications in the field of flexible electronics. Now, a TU Wien research team led by Thomas Müller has made a breakthrough in this field as part of an ongoing research project.

Two-dimensional materials, or 2D materials for short, are extremely versatile, although – or often more precisely because – they are made up of just one or a...
