Disposable credit card numbers

22.02.2008
A radical approach to shopping online without risking the security of your banking or credit card details has been devised by researchers at Anglia Ruskin University, in Chelmsford.

Writing in a recent issue of the Inderscience publication International Journal of Electronic Security and Digital Forensics Mohammed Assora, James Kadirire and Ayoub Shirvani explain how a disposable credit card number would protect consumers from fraud when shopping online.

Today, e-commerce transactions are performed by sending the customer's credit card details over the Internet between a web browser and the e-commerce site. Despite rudimentary security, there are many points at which the process can be compromised by a fraudster.

The most insecure aspect of the whole process, explains Shirvani and colleagues, is the client authentication step because most e-commerce sites usually only require the customer's credit card details to validate the sale. There is no certification on the customer's side of the bargain. This means that anyone who steals your credit card information could use it to buy goods and services online fraudulently.

Customer certification is not the only problem, the researchers say. Once you have entered your credit card details into a shopping or other e-commerce site, these are usually stored unencrypted in the merchant’s database, which means they could be retrieved by anyone with access to that database, whether or not that is an unscrupulous employee or someone breaking in to the database from outside.

The researchers point out that more than a decade has passed since computer security experts instigated the Secure Electronic Transaction

(SET) protocol to try to solve this problem by sending the client's credit card details encrypted. However, the system was very complicated and has not been adopted by e-commerce sites.

Instead, Shirvani and colleagues put forward the idea of a disposable credit card number (DCCN) that could overcome the vast majority of security threats. They describe how DCCNs could be generated "off-line" using a pre-shared secret key between the issuer and the customer and used only once to make an electronic purchase.

The concept is related to the credit voucher and gift certificate systems used by some e-commerce sites but the off-line system means no credit card details need pass across the Internet to create the voucher code. The off-line approach would also side-step any potential security and implementation issues that might be associated with online DCCNs such as Private Payment and SecureClick.

In off-line generation of DCCNs, the customer registers his/her credit card with the card issuer and receives an associated secret key. The customer will then use this secret key in conjunction with a simple calculation device such as a smart card, PDA or mobile phone to generate an encrypted code - known as a hash - that is based on the price of the goods he/she intends to purchase and other details pertinent to the e-commerce site.

The resulting hash is adapted to form the DCCN, and then sent over the Internet instead of the actual credit card details. The shopping site validates the DCCN as any normal credit card without ever seeing or having to store their real credit card details. As a result, the client can shop with no need to worry about confidential data being compromised, the researchers conclude.

Im Focus: Can we see monkeys from space? Emerging technologies to map biodiversity

An international team of scientists has proposed a new multi-disciplinary approach in which an array of new technologies will allow us to map biodiversity and the risks that wildlife is facing at the scale of whole landscapes. The findings are published in Nature Ecology and Evolution. This international research is led by the Kunming Institute of Zoology from China, University of East Anglia, University of Leicester and the Leibniz Institute for Zoo and Wildlife Research.

Using a combination of satellite and ground data, the team proposes that it is now possible to map biodiversity with an accuracy that has not been previously...

Im Focus: Climate satellite: Tracking methane with robust laser technology

Heatwaves in the Arctic, longer periods of vegetation in Europe, severe floods in West Africa – starting in 2021, scientists want to explore the emissions of the greenhouse gas methane with the German-French satellite MERLIN. This is made possible by a new robust laser system of the Fraunhofer Institute for Laser Technology ILT in Aachen, which achieves unprecedented measurement accuracy.

Methane is primarily the result of the decomposition of organic matter. The gas has a 25 times greater warming potential than carbon dioxide, but is not as...

Im Focus: How protons move through a fuel cell

Hydrogen is regarded as the energy source of the future: It is produced with solar power and can be used to generate heat and electricity in fuel cells. Empa researchers have now succeeded in decoding the movement of hydrogen ions in crystals – a key step towards more efficient energy conversion in the hydrogen industry of tomorrow.

As charge carriers, electrons and ions play the leading role in electrochemical energy storage devices and converters such as batteries and fuel cells. Proton...

Im Focus: A unique data centre for cosmological simulations

Scientists from the Excellence Cluster Universe at the Ludwig-Maximilians-Universität Munich have establised "Cosmowebportal", a unique data centre for cosmological simulations located at the Leibniz Supercomputing Centre (LRZ) of the Bavarian Academy of Sciences. The complete results of a series of large hydrodynamical cosmological simulations are available, with data volumes typically exceeding several hundred terabytes. Scientists worldwide can interactively explore these complex simulations via a web interface and directly access the results.

With current telescopes, scientists can observe our Universe’s galaxies and galaxy clusters and their distribution along an invisible cosmic web. From the...
