With the country facing increased terror threat, Prime Minister Manmohan Singh [Images] on Saturday regretted that modern technology is not adequately utilised to meet the challenge and pitched for greater focus on scientific developments for securing the nation better.

Pointing out that other countries have used technology for security with great effect, he favoured work in the areas of surveillance systems, cryptography, real time search and identification from distributed large databases and computer simulation exercises to enhance crisis tactics and responses.

"The role of technology in supporting our counter terrorism and internal security efforts is, I believe, not adequately appreciated," he said at a function in New Delhi [Images] to give away the Shanti Swaroop Bhatnagar Prizes to 21 young scientists.

Investment in security technologies is vital if the country's security systems are to keep pace with the increasing sophistication of international terrorism and crime, he said.

Dr Singh said scientific interventions should be used to 'neutralise weapons of terror and mass destruction'.

He said other countries have 'used modern science and technology in their security structures with great effect. It acts not only as a force multiplier but can also provide solutions to human problems relating to command, coordination and communication'.

The prime minister's emphasis on utilisation of modern technology significantly comes in the midst of government's efforts to revamp the security structures of the country in the wake of Mumbai attacks.

The government has already spelt out a slew of measures to meet the increased terror threat from land, sea and air.
