Description:
Norwegian's railway NSB (http://www.nsb.no) will install 3200 new security cameras into their coaches - filming anyone who is using a train in Norway. This is - according to Stein Nilsen, director of NSB's person transport - mainly a "preventive measure" against violence in trains (see Aftenposten, 25.Mar.2008,
http://www.aftenposten.no/nyheter/iriks/article2325143.ece.)
I couldn't find any hint to the technical security of the cameras and their videos, but it is good to know that NSB promises that "no one but the police and the train accident commission" can access the videos (NSB,
http://www.nsb.no/om_nsb/aktuelt/article28308-2707.html, 27.2.2008). This is according to requirements from the Norwegian data protection office(http://www.personvernnemnda.no/vedtak/2005_13.htm, which do not present any technical security requirements, however).
So until further notice, don't put your finger up your nose on Norwegian trains if you think someone might like to have you doing that on Newspaper.
Post Scriptum: Take a look at the Flexus RFID train ticket project in Oslo. It implements the Nordic E-Ticket specification (http://www.nsb.no/flexus/). Now - as a paparazzi - you could actually put up receivers at train stations that tell you who's boarding which train (with a RFID ticket), and then go steal the harddisks with the videos from these trains if you need celebrity photos. Cool!
