Brazil data plan aims to keep US spies at bay

Brazil is considering ways to make local use of the internet less dependent on US-based services, following leaks about Washington's cyberspy operations.

The South American nation has suggested forcing internet firms to open data centres in Brazil, which would be used to store locally generated material.

It is also pursuing a plan to build a new internet cable.

The project would offer a way for data to bypass the US.

Brazil's President, Dilma Rousseff, has postponed a state visit to Washington after allegations that the US National Security Agency (NSA) had targeted her emails and phone calls.

It has also been alleged that the NSA hacked state-run oil company Petrobras and intercepted billions of emails and calls to Brazilians.

US Secretary of State John Kerry has previously defended the NSA's actions, saying they were necessary to combat terrorism.
