We present a taxonomy of Internet censorship resistance strategies and techniques extracted from analyzing proposed and implemented systems. We categorize the strategies into the following six types to form the CORDON taxonomy: Collateral damage, where the damage caused by censorship would outweigh its benefits; Outside scope of influence, where the censor is powerless to act due to it having n...

Following the enactment of computer crime law in Thailand, online service providers are compelled to control illegal content including content that is deemed harmful or problematic. This situation leads to self-censorship of intermediaries, often resulting in overblocking to avoid violating the law. Such filtering flaw both infringes users’ freedom of expression and impedes the business of OSPs...

Despite the pervasive nature of Internet censorship and the continuous evolution of how and where censorship is applied, measurements of censorship remain comparatively sparse. Understanding the scope, scale, and evolution of Internet censorship requires global measurements, performed at regular intervals. Unfortunately, the state of the art relies on techniques that, by and large, require user...

The number of countries that censor and monitor their citizens’ use of the Internet is increasing. While it is no secret that China and Iran censor the Internet, at least 25 countries, including Pakistan, Ethiopia, Thailand and Uzbekistan, also have technical filtering regimes in place. Some of the technology is even exported by western companies: search engines, blog hosting providers and emai...

Freud's analogies were legion: hydraulic pipes, military recruitment, magic writing pads. These and some three hundred others took features of the mind and bound them to far-off scenes--the id only very partially resembles an uncontrollable horse, as Freud took pains to note. But there was one relation between psychic and public act that Freud did not delimit in this way: censorship, the proces...

Censorship, anti-censorship, and self-censorship in an authoritarian regime have been extensively studies, yet the relationship between these intertwined factors is not well understood. In this paper, we report results of a large-scale survey study ( $$N=526$$ ) with Sina Weibo users toward bridging research gap. Through descriptive statistics, correlation analysis, regression uncover how are b...

Over the years, the Internet has democratized the flow of information. Unfortunately, in parallel, authoritarian regimes and other entities (such as ISPs) for their vested interests have curtailed this flow by partially or fully censoring the web. The policy, mechanism, and extent of this censorship varies from country to country. We present the first study of the cause, effect, and mechanism o...

Tracking Internet censorship is challenging because what content the censors target can change daily, even hourly, with current events. The process must be automated because of the large amount of data that needs to be processed. Our focus in this paper is on automated probing of keyword-based Internet censorship, where natural language processing techniques are used to generate keywords to pro...
