Surveillance and Tecnology

I find it very interesting how the improvement of technology will affect the control and surveillance systems. Already while you are using the internet you leave a footprint on everything where you go and that has been used recently a lot for marketing purposes etc. For example it is pretty scary when facebook know that you have looked flights into somewhere and advertises them to you. I can see many problems if all the material of surveillance systems would leak out of the control of the government.

There is an interesting article about the topic below:
