New Delhi, Sep 17 (IANS): Police officers from various states, bureaucrats and representatives from IT companies Tuesday discussed the role of technology for better security in Indian cities.

The discourse at a conference and exhibition "Secure Cities 2013" here focussed on several challenges faced by cities in terms of cyber crime, threat to infrastructure and common people.

"We need to ponder whether the existing technology is sufficient to address security. We have a troubled neighbourhood and we need to secure vital installations like airports, railway stations and ports," K. Skandan, additional secretary in the ministry of home affairs, said.

Skandan cautioned against the "loose talks" in social media which, he said, could fan communal feelings and pose threat to harmony in the country.

Uttar Pradesh's Director General of Police O.P. Singh advocated the role of technology in changing the face of policing in the country.

"Technology will enhance the face of policing in the country," he said.

Singh rued the "failure" of technical tools during the communal violence in Muzaffarnagar in the state.

Sandeep Goel, joint commissioner in Delhi Police, echoed Singh's views.
