Wikipedia defines internet censorship as 'the control or suppression of what can be accessed, published, or viewed on the internet.' Internet censorship is sometimes carried out pervasively in several countries without a care for human rights. This censorship can directly be associated with authoritarian regimes.
Below is a list of the top ten countries that censor the internet at an alarming rate-
Cuba censors the internet in the form of lack of accessibility to the internet. Until quite recently Cubans were not allowed to purchase their own computers! Only five per cent of Cuba's population have access to the internet. The rest are allowed to use it in government-run cafes at an average cost of $8. Given the approximate weekly salary of $20, this option is too expensive for a Cuban. Thereby, denying the citizens access to the internet without having to use various unwieldy data filtering systems.
Cubans are allowed Facebook and Twitter, however, they are denied access to YouTube.
Censorship in Qatar falls under the purview of Qtel. According to Ahmed Rashid al-Suwaidi, Qtel Senior Manager said Qtel is blocking the websites in order "to maintain ethical standards and protect the culture of the society."
Qtel is given the responsibility to block all websites that contain pornographic content or are in some way criticise the Gulf leaders. Sites containing anti-Islamic elements are also blocked. In fact, websites containing dating services, gay and lesbian content are promptly removed by the authorities. Following such strict norms has led to the censorship of sites that are otherwise free of obscene media.
The extreme steps taken by the government has often been termed "The Great Firewall of China." Besides having the largest numbers of journalists arrested, social networking sites such as Facebook and Twitter were blocked in 2009. YouTube, Facebook and Twitter still remain blocked in China!
On the other hand, internet usage is not discouraged in China as the country wishes to build a strong modern economy. However, the Chinese government does not tolerate opposition in any form over the internet. In order to tackle it, it has developed the world's "most sophisticated" internet filtering system, according to the OpenNet Initiative.
The Iranian government's web filter uses long blacklists of forbidden URLs and URL keywords to prevent ordinary Iranians from accessing content deemed obscene, profane or seditious. The largest portion of blocked internet content has to do with politics and government (40%), followed by sex and sexuality (20%).
The Iranian authorities adopt a triangulated approach to internet censorship and surveillance. Preventative, interceptive, and reactive measures are infused to form a coherent overall strategy for internet control.
Internet traffic in Syria is filtered in several ways. IP addresses and domain names are filtered to block single websites such as amazon.com, entire network regions, or keywords to target specific content. Syria is one step ahead of Iran for having censored instant messaging tools such as Skype, and content-sharing sites such as Metacafe or Reddit.
Social media censoring is limited to specific content and pages, such as the "Syrian Revolution" page on Facebook. All requests with the keyword "proxy" are blocked to curb the use of censorship-evading proxies. However, this also has the effect of blocking adverts and certain plug-ins that have no relation to banned content.
The Vietnamese government adopted the Decree on Management, Provision, and Use of Internet Services and Information Content Online (Decree 72/2013-ND-CP) on July 15, 2013; it became effective on September 1, 2013.
The law bans bloggers and users of social media from quoting, gathering, or summarizing information from press organisations or government websites. The main justification for the law is to uphold national security. Having made a law that could easily infringe upon human rights, Vietnam has earned its place as number five on the list.
Information Network Security Agency or INSA looks after the censorship of data and websites on the internet in Ethiopia. The government through INSA's broad mandate engages in intrusive actions that violate privacy laws and free speech with complete impunity.
While the Ethiopian density of internet users is only about 1%, there is still a large community of bloggers whose websites, blogs, and Facebook pages have been blocked by the government. To the users, the blocks themselves look harmless because the browser simply notifies users that the server request has timed out.
The Sudanese government openly acknowledges blocking and filtering websites that it considers immoral and blasphemous. Content that is "morally offensive and violating public ethics" and that which "forestalls evil in the society" is filtered pervasively.
Sudan is infamous for its manipulation of data, and self-censorship during the election periods in the country. There is no distinction for social media. All content is under one umbrella and is filtered or censored accordingly, thereby making Sudan number three on the list.
2. Saudi Arabia
Blocking in Saudi Arabia is done with reference to two lists: one of "immoral" (mostly pornographic) sites; the other based on directions from a security committee run by the ministry of interior.
Citizens are encouraged to actively report "immoral" sites for blocking, with hundreds of requests made every week. Far from concealing their actions, the authorities openly attest to their censorship practices and claim to have blocked some 400,000 sites.
1. North Korea
Only selected individuals are allowed access to the internet in North Korea. Internet censorship is at its best as the censorship is tackled at its start, which is at the access point. There are only about 1024 IP addresses as opposed to about a hundred million in any developed country.
Shocking as it may sound, there's just one cybercafe in North Korea's capital, Pyongyang. Anyone logging on at the cafe would find themselves at a computer that isn't running Windows, but instead Red Star – North Korea's own custom-built operating system.
North Korea's technology infrastructure is described as a "mosquito net", allowing only the bare essentials both in and out. This intranet was opened in 2000 and includes a search engine, email, news coverage and a browser. There are around 1,000 to 5,500 websites on the service, according to the Toronto Star, and external websites are occasionally made available on request – although after being downloaded, censored and hosted locally. North Korea with its mosquito net technology has made it to number one on the list.
