On-line Banking security: a decisive competitive factor

This should on its own be an inducement to become more intensively engaged with the electronic business sector. For a large number of customers the range of online services offered is already a decisive factor in the choice of "their" bank. Whereas in the beginning the focus is on criteria such as the scope of services and costs, with increasing Internet experience the factor of data security develops into a core criterion.

And it is particularly in this sector however that the banks need to catch up. When protection during the transmission of personal account data via the Internet is involved, many people still put their trust in the conventional PIN/TAN system. Recent reports show however that these methods are not sufficient to suppress organised cyber crime. The market is lucrative and fraudsters are creative in the development of perfidious methods of stealing data, such as phishing, pharming and Trojans. According to the IT national association, Bitkom, in 2007 around 4100 cases with a total loss in the region of tens of millions came to light with an average loss amount of approximately €3,700. The Federal Criminal Police Office (BKA) registered in 2008 alone 1800 successful attempts to crack the i-TAN method based on an indexed TAN list.
