Olá a todos

Como tem sido notícia, prepara-se o primeiro projecto para a  
instalação sistemática de câmaras de vigilância em espaços públicos  
ao ar livre numa cidade portuguesa (Porto), anunciando-se já, à  
boleia das "ondas de violência", projectos semelhantes para outras  
cidades, incluindo Lisboa. Trata-se de uma alteração radical da ideia  
de cidade.

No jornal Variant, de Glasgow, publica-se um artigo de Manu Luksch &  
Mukul Patel [Faceless: Chasing the Data Shadow] que descreve  
sumariamente a situação no Reino Unido, pioneiro e actual campeão da  
vídeo vigilância  em espaços públicos, com um total estimado de 4,2  
milhões de câmaras de CCTV. Os autores apresentam também um projecto  
que pretende criar um pequeno efeito disruptivo sobre este gigantesco  
sistema de vigilância.
Talvez nos ajude a perceber melhor aquilo que se prepara por cá.

Faceless: Chasing the Data Shadow
Manu Luksch & Mukul Patel

Stranger than fiction
Remote-controlled UAVs (Unmanned Aerial Vehicles) scan the city for  
anti-social behaviour. Talking cameras scold people for littering the  
streets (in children?s voices). Biometric data is extracted from CCTV  
images to identify pedestrians by their face or gait. A housing  
project?s surveillance cameras stream images onto the local cable  
channel, enabling the community to monitor itself.
These are not projections of the science fiction film that this text  
discusses, but techniques that are used today in Merseyside1,  
Middlesborough2, Newham and Shoreditch3 in the UK. In terms of both  
density and sophistication, the UK leads the world in the deployment  
of surveillance technologies. With an estimated 4.2 million CCTV  
cameras in place, its inhabitants are the most watched in the world.4  
Many London buses have five or more cameras inside, plus several  
outside, including one recording cars that drive in bus lanes.
But CCTV images of our bodies are only one of many traces of data  
that we leave in our wake, voluntarily and involuntarily. Vehicles  
are tracked using Automated Number Plate Recognition systems, our  
movements revealed via location-aware devices (such as cell phones),  
the trails of our online activities recorded by Interent Service  
Providers, our conversations overheard by the international  
communications surveillance system Echelon, shopping habits monitored  
through store loyalty cards, individual purchases located using RFID  
(Radio-frequency identification) tags, and our meal preferences  
collected as part of PNR (flight passenger) data.5 Our digital selves  
are many dimensional, alert, unforgetting.
Increasingly, these data traces are arrayed and administered in  
networked structures of global reach. It is not necessary to posit a  
totalitarian conspiracy behind this accumulation ? data mining is an  
exigency of both market efficiency and bureaucratic rationality. Much  
has been written on the surveillance society and the society of  
control, and it is not the object here to construct a general  
critique of data collection, retention and analysis. However it  
should be recognised that, in the name of efficiency and rationality  
? and, of course, ?security? ? an ever-increasing amount of data is  
being shared (also sold, lost and leaked6) between the keepers of  
such seemingly unconnected records as medical histories, shopping  
habits, and border crossings. Legal frameworks intended to safeguard  
a conception of privacy by limiting data transfers to appropriate  
parties exist. Such laws, and in particular the UK Data Protection  
Act (DPA, 1998)7, are the subject of investigation of the film Faceless.
