Internet Filtering in China 2004-2005

China's Internet filtering regime is the most sophisticated effort of its kind in the world. Compared to similar efforts in other states, China's filtering regime is pervasive, sophisticated, and effective. It comprises multiple levels of legal regulation and technical control. It involves numerous state agencies and thousands of public and private personnel. It censors content transmitted through multiple methods, including Web pages, Web logs, on-line discussion forums, university bulletin board systems, and e-mail messages. Our testing found efforts to prevent access to a wide range of sensitive materials, from pornography to religious material to political dissent. We sought to determine the degree to which China filters sites on topics that the Chinese government finds sensitive, and found that the state does so extensively. Chinese citizens seeking access to Web sites containing content related to Taiwanese and Tibetan independence, Falun Gong, the Dalai Lama, the Tiananmen Square incident, opposition political parties, or a variety of anti-Communist movements will frequently find themselves blocked. Contrary to anecdote, we found that most major American media sites, such as CNN, MSNBC, and ABC, are generally available in China (though the BBC remains blocked). Moreover, most sites we tested in our global list's human rights and anonymizer categories are accessible as well. While it is difficult to describe this widespread filtering with precision, our research documents a system that imposes strong controls on its citizens' ability to view and to publish Internet content. This report was produced by the OpenNet Initiative, a partnership among the Advanced Network Research Group, Cambridge Security Programme at Cambridge University, the Citizen Lab at the Munk Centre for International Studies, University of Toronto, and the Berkman Center for Internet & Society at Harvard Law School

Internet Filtering in China

We collected data on the methods, scope, and depth of selective barriers to Internet usage through networks in China. Tests conducted from May through November 2002 indicated at least four distinct and independently operable Internet filtering methods - Web server IP address, DNS server IP address, keyword, and DNS redirection with a quantifiable leap in filtering sophistication beginning in September 2002

The Impact of Information Security Technologies Upon Society

This paper's aims are concerned with the effects of information security technologies upon society in general and civil society organisations in particular. Information security mechanisms have the potential to act as enablers or disablers for the work of civil society groups. Recent increased emphasis on national security issues by state actors, particularly 'anti-terrorism' initiatives, have resulted in legislative instruments that impinge upon the civil liberties of many citizens and have the potential to restrict the free flow of information vital for civil society actors. The nascent area of cyberactivism, or hactivism, is at risk of being labelled cyberterrorism, with the accompanying change of perception from a legitimate form of electronic civil disobedience to an abhorrent crime. Biometric technology can be an invasive intrusion into citizens' privacy. Internet censorship and surveillance is widespread and increasing. These implementations of information security technology are becoming more widely deployed with profound implications for the type of societies that will result

How Wikipedia Can Overcome the Great Firewall of China

Oil is the main insulation in power transformers and over long time of ageing its insulation properties can change. In this paper ageing of oil due to the exposure to electric discharges was investigated. The effect of high energy discharges (complete arc) and low energy discharges (partial discharges) on oil properties such as breakdown strength and oil conductivity was investigated. An experimental setup consisting of two spherical electrodes was designed. The adjustable distance between the two electrodes made it possible to have PD with different magnitude. The oil conductivity and breakdown strength was measured for three sets of experiments. The first group of experiments was performed on new oil in order to have a reference for comparison. In the second group of experiments the new oil samples was exposed to 1000 and 3000 lightning impulses. In the third group of experiments new oil samples was exposed to partial discharge for different duration of time. Oil conductivity and breakdown strength of these aged samples were compared with new oil. The results show that after exposure to lightning impulse oil conductivity increases and breakdown strength decreases, However PD activity for short time does not change the oil conductivity but it reduces the breakdown strength.QC 20140107</p

Breaching the Great Firewall: China’s Internet Censorship and the Quest for Freedom of Expression in a Connected World

In the final days of 2005, Microsoft Corporation made international headlines when it removed the site of a Beijing researcher from its blog hosting service. Soon, other instances of U.S. companies assisting in China’s internet censorship emerged. These revelations generated outrage among commentators and legislators and led to calls for action. This Note examines the methods of internet censorship employed by China and other nations, and explores the assistance that U.S. companies have provided to these nations. It analyzes the liability issues facing these companies in light of existing case law and statutory solutions proposed in the U.S. Congress. It then proposes a novel combination of existing legislative proposals, recommendations from the Electronic Frontier Foundation, and international cooperation as the best way to address the problem of internet censorship

Government Control Of Communications Technology

The internet allows for the sharing of knowledge, communications, and business transactions on a global scale. Governmental regulation of the internet varies among different countries and regions of the world.  The benefits and burdens of such regulatory policies should be considered
