If you care about anything, then you probably like your opinion to be counted (or maybe that reflects on me somehow)… Let’s move on!
If you do want your opinion to be counted, though, why not join YouGov and get paid a small amount for contributing to the opinion poll results: sign up with YouGov
I went to London today and on the way I read my favourite magazine, Scientific American. The issue I was reading was a special issue focussing on privacy in the modern world (September 2008).
I have a profile on Facebook and, heck, a website here where I occasionally say something that I feel needs saying (less frequently recently). I also use Google to search and only rarely delete anything from my search history. But the article I was reading that triggered the ‘must write’ response was one on RFID tags.
When I first decided to get an Oyster card it was after a long period of thinking about it. To me having the Mayor of London able to see where I’m going seemed like a bit of an imposition. Why should he need to know where I’m going? And can I trust a man who leaves the Congestion Charge cameras on on Sundays? Eventually I decided that as it was voluntary it wasn’t unreasonable to help them manage the network and, anyway, it’s cheaper for the right reasons.
But as I read the RFID article I realised how many things I was carrying had an RFID tag in them. I was going to an examination so I had my new-style passport with me as ID. This contains a passive chip that is encrypted (I believe) using my passport number as a key. But also on my person I had said Oyster card and also my new Barclaycard that has PayPass.
If I wander into a shopping centre, the article explained, an array of RFID tag readers in appropriate places may just be able to read my RFID tags and find out where I go, where I stop or dally and where I don’t go. While, at the moment, this would not necessarily identify me as me, it wouldn’t be too hard for that to happen and it would be much easier to integrate that data into a useful database than are images on CCTV.
I have to admit, despite my concerns about freedom I am not worried about the implementation of RFID in the West yet (China’s another matter: China to issue RFID ID cards) but it is an area we need to keep an eye on.
