BERLIN -- When the Austrian government passed a law this year allowing
police to install closed-circuit surveillance cameras in public spaces without
a court order, the Austrian civil liberties group Quintessenz vowed to watch
Members of the organization worked out a way to intercept the camera images
with an inexpensive, 1-GHz satellite receiver. The signal could then be descrambled
using hardware designed to enhance copy-protected video as it's transferred
from DVD to VHS tape.
The Quintessenz activists then
began figuring out how to blind the cameras with balloons, lasers and infrared
And, just for fun, the group created an anonymous
surveillance system that uses face-recognition software to place a black
stripe over the eyes of people whose images are recorded.
Quintessenz members Adrian Dabrowski and Martin Slunksy presented their video-surveillance
research at the 22nd annual Chaos
Communication Congress here this week. Five hundred hackers jammed into
a meeting room for a presentation that fit nicely into CCC's 2005 theme of "private
Slunksy pointed out that searching for special strings in Google, such as axis-cgi/,
will return links that access internet-connected cameras around the world. Quintessenz
developers entered these Google results into a database, analyzed the IP addresses
and set up a website that gives users the
ability to search by country or topic -- and then rate the cameras.
"You can use this to see if you are being watched in your daily life,"
The conference, hosted by Germany's Chaos Computer
Club, featured many discussions on data interception and pushing back the
unprecedented onslaught of surveillance technologies.
Even the Dutch, once known as hacker-friendly, politically progressive Europeans,
are now fearful and demanding more cameras on their streets, said Rop Gonggrijp,
founder of Dutch ISP Xs4All.
Gonggrijp says the Dutch chief of police has announced the intention to store
large amounts of surveillance data and mine it to determine who to pressure
and question. "People are screaming for more control," said Gonggrijp.
Dutch journalist Brenno de Winter warned that the European Parliament's support
for data retention doesn't ensure security, and makes citizens vulnerable to
automated traffic analysis of who communicates with whom through phone calls
and internet connections. "What we have seen is a system that fails because
we miss out on too much information, and even if we have all that information,
it doesn't give us the right information and it is easy to circumvent,"
said de Winter.
CCC member and security researcher Frank
Rieger said hackers should provide secure communications for political and
social movements and encourage the widespread use of anonymity technologies.
He said people on the other side of the camera need to be laughed at and shamed.
"It must not be cool anymore to have access to this data,"
said Rieger, who argued that Western societies are becoming democratically legitimized
police states ruled by an unaccountable elite. "We have enough technical
knowledge to turn this around; let's expose them in public, publish everything
we know about them and let them know how it feels to be under surveillance."
The four-day Chaos Computer Congress is meeting near Alexanderplatz in the
former East Berlin, where more than a half-million people rallied for political
reform five days before the fall of the Berlin Wall.
In his keynote address, Joichi Ito, general
manager of international operations for Technorati,
warned that the internet could itself become a walled-in network controlled
by the International Telecommunication Union,
Microsoft and telecommunications companies.
Ito said these restrictions would stifle free speech and the ability to question
authority without retribution. "An open network is more important for democracy
than the right to bear arms and the right to vote," said Ito. "Voice
is more important than votes."
