Take a look at the pdf and go to page 28 and there are some bullet points stating.
• Access control through continued use of gating on stations willSo, all stations to have new security gates, linked to CCTV with facial recognition systems and also looking for "abnormal behaviour" (whatever that may be considered to be).
• Scanning for passenger numbers and weapons remains an option,
although the risk needs to be balanced against the disadvantages in
terms of capacity;
• Closed-circuit television (CCTV) will continue to be developed, including automatic face recognition and detection of abnormal behaviour;
Now think about those lovely ID cards, and how you could incorporate such technology with them and use it to justify even greater monitoring of our movements on the grounds of security?
Go through gate, have your face scanned, have it mapped against the ID database, monitroing whether you're sweating, twicthing, looking a bit dodgy. Nicked.
