Bush rejects cyber-terrorist ID cards

US President Bush has given the thumbs down to a national identification card scheme as a way to combat cyber-terrorism.

Richard Clark, special advisor on cyber-terrorism to the Bush administration, told delegates at Microsoft's Trust Computing Conference in California, that the idea was not gaining support in Washington.

He said many politicians had said it was a bad idea. Instead, he suggested a system to track movement across US borders and for those who travelled by plane in and out of the US.

But this is one of many different the US government is considering, Clark added.
