Tackling terror with technology

More technology may not have stopped the attacks

By BBC News Online technology correspondent Mark Ward

Experts are warning of the risk of relying on technology to help spot terrorists before they attack.

Everyone is outraged by the terrorist attacks, but that's no reason to suddenly abrogate our rights

They say that the low tech methods used by those behind last weeks attacks on New York and Washington show it was basic failures in intelligence work rather than too little technology that gave the the hijackers their opportunity.

Civil liberty groups add that intelligence agencies already have more than enough freedom to intercept communications and acquire records of electronic communications, and caution against handing over yet more powers to allay short-term fears.

Imposing restrictions on technologies that can be used to secure messages will do little to combat terrorism, they say, but could seriously erode personal privacy.

Hidden messages

The FBI has revealed few details of how last week's attacks were co-ordinated.

But, even so, it is clear that far from being a sophisticated operation using false identities, elaborate cover stories, uncrackable encryption and the highest of technology, the hijack assault was an extremely low tech mission.

The hijackers used their own names, public web terminals, frequent flier identifiers, and unencrypted e-mail messages to keep in touch.


Conversations can be hidden in a crowd

"We are all focusing on this as a very hi-tech war, whereas the terrorists are using very low-tech means," said Brian Gladman, former technical director at Nato, and now an advisor to the net thinktank the Foundation for Information Policy Research (Fipr).

There were good reasons for keeping communications so simple, he said: "There's so little encryption going across the net that any that is used stands out like a sore thumb."

Reports suggest that the sophisticated technologies available to intelligence agencies mean that those planning attacks tend to favour low-key methods that are far harder to pick out and track. Many groups use messages passed by trusted messengers and word of mouth rather than electronic networks.

To avoid raising the suspicions of intelligence agencies, the groups are thought to fix the meaning of seemingly innocuous messages long before attacks take place. A message such as "See you in New York on the 11th" sounds innocent and its significance would only become apparent after the event.
