A very well written paper on privacy and security issues, by the UK’s Royal Academy of Engineering’s group on Privacy and Surveillance. The United Kingdom is a very interesting sociological organism for studying security and privacy. They are much, much closer to being a surveillance society than the U.S. is, and us lucky folk over here in the former colonies can learn quite a bit about security tradeoffs by examining evaluations of the U.K.’s tactics and effectiveness.
Realistically estimating ROI on IT projects is a supremely difficult task; we don’t have to hypothetically crunch numbers when deciding how to spend “homeland security” dollars when we can get access to data from Old Mother England. It will save us a lot of time, a lot of money, and probably prevent us from taking major missteps when it comes to security vs. liberty if we pay attention to what’s going on elsewhere.
