Using tech to prevent losses

In the midst of corporate scandals, many companies have started using some sort  technology to prevent individuals from conducting fraudulently activity.  In the wake of the recent scandal at Société Générale, an individual alone caused an estimated $7 billion loss for the company.

Jérôme Kerviel, a 31 year old trader was at the center of the scandal.  Kerviel who had rudimentary computer skills was able to access personal information because he had password of his colleagues.  At the heart of most security systems, there is a one factor authorization systems.  In most cases it is a password.  However new technology has allowed companies to employ a three factor authorization system, a password, ID cards and fingerprints.  It may be easy to obtain a password or ID card, but it may be difficult to obtain both.  However with all this security, it does make accessing systems more inconvenient as well as expensive.
