New Delhi, Sep 30 (IANS): Over 70 per cent of terrorists and terror groups across the globe are using various cyber medium tools to spread the evil of terrorism and further their goals, Gulshan Rai, the National Cyber Security Coordinator in the Prime Ministers Office (PMO) has said.

Speaking at the India Conference on Cyber Security & Internet Governance organised by Observer Research Foundation here, Rai said 70-75 per cent of terrorists are using tools like voice over internet telecom, social media and even encryption to spread the menace of terrorism and further their goals.

He said that post the controversy surrounding whistle-blower Edward Snowden, users and nations have become worried about the security of their data and are now using various encryption techniques and policies that has led to interruptions in seamless flow of data and information.

Former Central Intelligence Agency (CIA) employee Snowden copied and leaked classified information from the National Security Agency (NSA) in 2013 without prior authorisation.

Stressing on the need for finding a fine balance between the security and seamless flow of data, Rai said India is coming out with the national encryption policy with the focus on multi-stake holder model.

Based on public private partnership, the model, will have the government, industry, academia and the civil society working together to ensure a perfect balance between security and smooth flow of data.

The three-day international conference that began on September 28, was inaugurated by Union Minister for Information Technology & Law and Justice, Ravi Shankar Prasad.
