Global net censorship 'growing'

BBC

The level of state-led censorship of the net is growing around the world, a study of so-called internet filtering by the Open Net Initiative suggests.

The study of thousands of websites across 120 Internet Service Providers found 25 of 41 countries surveyed showed evidence of content filtering.

Websites and services such as Skype and Google Maps were blocked, it said.

Such "state-mandated net filtering" was only being carried out in "a couple" of states in 2002, one researcher said.

"In five years we have gone from a couple of states doing state-mandated net filtering to 25," said John Palfrey, at Harvard Law School.

Mr Palfrey, executive director of the Berkman Center for Internet and Society, added: "There has also been an increase in the scale, scope and sophistication of internet filtering."

ONI is made up of research groups at the universities of Toronto, Harvard Law School, Oxford and Cambridge.

It chose 41 countries for the survey in which testing could be done safely and where there was "the most to learn about government online surveillance".

A number of states in Europe and the US were not tested because the private sector rather than the government tends to carry out filtering, it said.

Countries which carry out the broadest range of filtering included Burma, Iran, Pakistan, Saudi Arabia, Syria, Tunisia, the United Arab Emirates and Yemen, the study said.........
