Iran's Complex Content- Tracking
The Iranian government has gone far beyond smashing computers, blocking
access to Web sites or breaking Internet connections in an effort to stop
citizen journalists from reporting within Iran and to keep the foreign
media out.
The Iranian government performs online-content inspection on a national
scale and coordinated at a single location.
With assistance of European telecommunications companies, the Iranian
government has developed "one of the world's most sophisticated
mechanisms for controlling and censoring the Internet."
In an attempt to censor its people, the Iranian government has been
tracking the content of individual online communications through a
practive called deep packet inspections.
According to the WSJ, "Deep packet inspection involves inserting
equipment into a flow of online data, from emails and Internet phone
calls to images and messages on social-networking sites such as Facebook
and Twitter. Every digitized packet of online data is deconstructed,
examined for keywords and reconstructed within milliseconds. In Iran's
case, this is done for the entire country at a single choke point,
according to networking engineers familiar with the country's system."
Reports from Iranian Internet users saying that the Internet is running
at less than a tenth the speed it usually does may be a sign of the
government's use of deep packet inspections. Without an increase in
processing power, the online data filtering system would lead to drastic
delays in online transmission.
Blocking websites is no longer a viable option for censoring its people
since videos like the one of a young Iranian woman named Neda can be sent
out online and posted by multiple users outiside of Iran.
Repressive regimes, such as the one in Iran, the scanning of messsage by
message from a central "monitoring center" has allowed the government to
to choke the flow of information and the use of deep packet inspections,
which enable authorities to not only block communication but to "monitor
it to gather information about individuals, as well as alter it for
disinformation purposes."
