We have already read of cases of hard discs and laptops carrying banking information being sold on e-bay.
What happens to the systems of banks or brokers who go into administration?
The personal details of formerly high wealth individuals may well be the most valuable remaining asset.
Will the administrator sell these to the highest bidder?
Will the equipment also be sold to highest bidder - who will can costs by not cleaning it before selling on or exploiting tax breaks for charitable giving?.
The chief executive of Computer Aid is trying to get work done to ensure that equipment is not simply dumped by those claiming to be acting for charitable purposes. As part of this there is a petition on the Number 10 website. The Prime Minister has other priorities at present but action to protect personal electronic banking records needs to be part of the small print of rescue packages and negotiations with the Icelandic government and others.
