Twitter CEO Dick Costolo has stated that the company complies with rules when it receives valid legal requests for information about its users in the countries in which it operates.
Costolo appeared at the Center for Technology Innovation at the Brookings Institution in Washington, US.
He added that the company pushes back when it receives requests more broad in scope that don’t meet its principle of being a specific valid legal request.
Costolo was quoted by Brookings Institution as saying that transparency reports go a long way toward helping people understand which requests are legally valid, and which are rejected.
He called on the technology sector to place heavier emphasis on transparency reports in order to foster trust with users.
Twitter, which currently has more than 200 million users, was not among the companies which were tapped by the National Security Agency and the FBI under US surveillance programme, Prism.
Last month, Twitter introduced an optional ‘two-factor authentication‘ feature using mobile phone verification on the social network, as part of its efforts to beef up security.
