Growing cyberspace controls, Internet filtering

   Governments in many parts of the world have been aggressively adopting a new generation of controls aimed at filtering and controlling information flow on the Internet, citing concerns such as cyber security, crime and terrorism, according to the OpenNet Initiative.

The OpenNet Initiative, which says it “investigates and analyses Internet filtering and surveillance practices in a credible and non-partisan fashion,” in its updated study released last year titled, “Access Controlled: The Shaping of Power, Rights, and Rule in Cyberspace,” said that it was fast becoming the global norm to control information flow on the Internet.

The OpenNet is a collaborative partnership between the Citizen Lab at the Munk School of Global Affairs, University of Toronto, the Berkman Centre for Internet and Society at Harvard University, and the Ottawa-based SecDev Group.

Asked whether the trend was likely to become more pronounced, given the recent developments in the Middle East, one of the contributors to the study, Ethan Zuckerman, a senior researcher at the Berkman Centre, said, “In general, we see governments becoming more aggressive and more overt about their Internet filtering.”

The OpenNet has described the recent Internet blackout in Egypt as ‘just-in-time-blocking' - when information flow is brought to a halt during critical times such as political crises, elections, or social unrest. Discussions have resurfaced about the deployment of 'Internet kill switches,' a way in which nations could snuff out the Internet when such a crisis occurs.

“For all the talk of Internet kill switches, turning off the Internet is a relatively easy and unsophisticated thing to do. What is hardest to do is filtering on finer, more granular levels,” Mr. Zuckerman told The Hindu.

The first-generation controls were deployed primarily at Internet “choke points,” places in the network where Internet addresses that had been blacklisted by the authorities could be filtered and blocked. These were mainly the gateways run by the Internet Service Providers (ISPs). The number-based IP addresses connected to particular websites or domain names could be used for the blocking. Keywords could also be used in weeding out proscribed sites or pages.

Reports of watchdogs such as the OpenNet and Freedom House indicate that though not pronounced, selective filtering has been a part of the Indian Internet scene. Google's Transparency Report for the first half of 2010 also shows that India is among the nations from where a number of government inquiries for information about users and requests to remove or censor content emanate.

“As far as censorship of Internet goes in India it is still first generation in terms of blocking and filtering at the Internet choke points. However, the Indian government has made and is making several moves that continue to undermine privacy and anonymity on the Internet. This has a chilling effect on freedom of expression and information accessing behaviour on the Internet,” says Sunil Abraham, executive director of the Bangalore-based Centre for Internet and Society.

Breaking news: Google launches new African tech incubator

Google has chosen Cape Town as a pilot for a new technology incubator called Umbono which aims to bring together seed capital, Google mentorship, angel investors, local tech stars, entrepreneurs and business leaders. If successful in Cape Town, Google may take the model to other parts of the globe. Google says it chose Cape Town because the city is in “the process of positioning itself as a hub for innovation and technology”. The search engine expects that successful funders will move to Cape Town and work “onsite” to take advantage of the opportunity. The search monolith says the incubator is “in keeping with its ongoing commitment to foster innovation in Africa” and it will help selected startup teams transform their ideas into companies.
