Singapore: Regulation or censorship?

Cryptography as a means to counter Internet censorship

George Orwells depiction of dystopia in his classic 1984, a society devoid of privacy, may have seemed like an exaggeration in 1949. But, with technology intruding deep into our lives today, we may actually be heading into a less obvious version of a similar state.

Jacob Appelbaum, prolific hacker and a close associate of WikiLeaks founder, Julian Assange, portrayed a grim picture of the future of the Internet when he was in Bangalore this week. He and the group of international hackers he is part of, Cypherpunks, propagate the idea of using cryptography on the Internet to counter surveillance and censorship on the Internet.

Traffic analysis

Censorship is the byproduct of surveillance, wrote Mr. Appelbaum in the book Cypherpunks: Freedom and Future of the Internet, which he has co-authored with Mr. Assange. For mass surveillance of the Internet, the first prerequisite is traffic analysis, a systematic logging of user activity and building profiles of users.

Features such as targeted advertisements are apparently more benign manifestations of traffic analysis.

Gmail and Facebook, for instance, analyse user traffic and activity, and deliver targeted ads, which is a boon to commerce on the Internet. But, the method adopted raise concerns about privacy, and in many cases can be considered an intrusion. For instance, when Google displays ads about pizza parlours after you have read a mail from a friend mentioning the word pizza, it does make one think as to what else Google might know about users.

Google and Facebook are able to identify and profile users because he or she is logged into their services, and have voluntarily identified themselves and have signed away the rights. This makes it easy for these Internet giants to log user activity, attribute it to the users, run social graph programs and build a comprehensive profile of users. While Google and Facebook require users to be logged into their service to profile them, it is possible to monitor users simply by analysing the traffic emanating from their Internet Protocol (IP) addresses. This is commonly known as traffic analysis and is the first prerequisite for surveillance.

IP addresses are numbers which can be attributed to people using the Internet; think of IP addresses in the Internet as vehicle registration numbers in the real world. When the IP addresses are monitored for activity, they reveal information about users. Concealing IP addresses is thus the first level of anonymity for users.

Data retention

Browsing the Web without the necessary precautions such as using unencrypted browsing, is akin to sending a postcard by mail instead of using envelopes. The data on unencrypted links can be seen transparently while they are being travelling from source to destination, with very little technical effort.

China trying new form of 'Internet censorship'

China is experimenting with more subtle methods to censor Internet search results ahead of the 24th anniversary of the Tiananmen Square crackdown, according to a group that monitors blocked websites in the country.

In the past, a search for keywords in China related to the events of June 4, 1989, came up with an explicit message saying: "According to relevant laws, regulations and policies, search results for (the blocked keyword) can not be displayed."

But GreatFire.org said in the lead up to the anniversary certain searches, such as "June 4 incident", had been intermittently returning a series of "carefully selected results", though it was impossible to click through to the actual webpages.

The organisation said this was an example of "censorship at its worst", with users duped into believing the keyword they were searching for was not a sensitive topic.

Troops killed hundreds of protesters during the pro-democracy protests in Beijing, but GreatFire.org said searches for "Tiananmen incident" returned links to an unrelated happening in the square from 1976.

It said the changes were not applied consistently, concluding that the authorities were conducting tests to improve their control systems.

The Internet in China is purged of politically sensitive websites and Beijing closely monitors the hundreds of millions of web users to prevent organised dissent. Twitter, YouTube and Facebook are banned.

The system of online censorship is dubbed the "Great Firewall", a term combining the words "Great Wall" and computer "firewall".

Internet Censorship in China

U.S. Role in the World

Across the world, internet users remain concerned probably increasingly so about what it might mean to lose control over their personal information online. In the United States, these fears may translate into efforts to make personal data more secure and even less permanent, through efforts such as the Do Not Track movement and advocacy tore-examinedated policies about email privacy.In China, where the governments surveillance and control over the internet is arguably peerless, users are of course concerned about privacy but also about the government erasing their accounts and data forever.

Recently in The Guardian, Chinese author Murong Xuecun wrote about the experience of having his social media accounts deleted by the Chinese government because of his views and writing. (Helen Gao, a friend and China-based writer who contributed to one of my previous blog posts translated it.) Ive highlighted a few of his observations about Chinas internet censorship below, and I highly suggest reading the whole article:

Almost every department and dignitary can order internet companies to delete information and accounts while they themselves hide in the dark. Seeing speeches that trigger their ire, they can make them disappear for ever by simply picking up the telephone receiver.

Netizens often compare being silenced on the Chinese internet to being put to death, and registering a new account is likened to reincarnation. Most Weibo [a Twitter-like service in China] users are familiar with the term the Reincarnation party. It has come to symbolise peoples resistance and struggle against censors. Every member of the party shares the same experience: being killed, and reincarnated; killed again, reincarnated again.The record-holder is a user named Repair. As of 13 May, she has reincarnated 418 times. If she is unable to use that name, she will become Re-pair, Repare or ReIpair.

My next reincarnation is going to be more difficult. The Chinese government makes sure its internet technology keeps pace with the times, which leaves me effectively no loophole to exploit. On the morning of 13 May, I attempted to re-register on Weibo, and after an hour of typing almost 30 versions of verification codes, I still couldnt get registered. My IP address, which is static, has been blocked. Registering a new account would require a verification code to be sent to a mobile number. I have only one mobile phone, which has similarly been blocked.

Murong Xuecuns experience paints a picture of an internet that defies dissidents workaround solutions and where the government and users are trying to out-innovate one another. For me, the issue of Chinese internet freedom is interesting for two reasons. One, it raises the question of how the Chinese government will handle dissent and protest as the country continues to evolve socially and economically right now, incidents like these seem to suggest that the government is hoping for a very literal version of the more things change, the more they stay the same adage.

Second, when it comes to internet issues more broadly, Chinas internet is unique in the scope of its control and the manpower the government puts behind this project (possibly up to 100,000 workers, according to The Economist). The party has achieved something few had thought possible: the construction of a distinct national internet, an April Economist article argues, making the case that China challenges the view that the internet facilitates democracy (Evgeny Morozov and Rebecca MacKinnon are also well worth reading on this point).

As the censorship issue continues to be battled out on Chinas computers, tensions between the U.S. and China over cyberattacks loom large, making it unlikely that internet freedom and human rights issues will come to play a prominent role on the bilateral cyberissues agenda.
