Peekabooty aims to banish internet censorship
14:31 19 February 02
A long-awaited computer program that can circumvent government
censorship of the internet has debuted at a computer conference in the
US.The program - Peekabooty - promises to give people in countries
such as China and Saudi Arabia safe access to the whole of the
internet. In these countries, internet access is controlled by
government-operated ISPs, which blacklist certain web sites. This may
include news sites that are deemed unsympathetic to government
policy.Peekabooty relies on users inside and outside a
government-imposed "firewall" downloading software. Restricted content
can then be delivered using volunteer "nodes" outside the restricted
zone communicating with users within. The content is disguised as
encrypted browser traffic, which is normally used to transmit credit
card information or sensitive information such as passwords. Hidden
identity Peekabooty uses a complicated communications system to allow
users to share information while revealing little about their
identity. When a node receives a request for a web page it randomly
decides whether to pass this on or access the page itself. It also
only knows the address of its nearest partner. This makes it difficult
to determine who requested what information and is designed to protect
users from anyone trying to infiltrate the system from inside."Many
people live under fear of repression," says Malcom Hutty of the UK's
Campaign Against Censorship of the Internet in Britain. "Ultimately
these things will work, because people want and need them."In the
past, some internet sites could be used to beat internet censorship.
These sites, such as SafeWeb and Anonymizer, acted as go-betweens,
delivering censored content indirectly. But government censors became
wise to this, and blocked access to these sites. Because content
viewed using Peekabooty is disguised, government agencies should not
be alerted to uncensored internet use. SafeWeb launched another
program designed to route content through volunteer computers called
Triangle Boy in 2001. But this does not maintain the anonymity of
users.Peekabooty was demonstrated at the CodeCon 2002 conference, in
California. Will Knight

            It was all so 
different before everything changed.
