Surveillance UK: why this revolution is only the start

From By Steve Connor, Science Editor, The Independent

The new national surveillance network for tracking car journeys, which has taken more than 25 years to develop, is only the beginning of plans to monitor the movements of all British citizens. The Home Office Scientific Development Branch in Hertfordshire is already working on ways of automatically recognising human faces by computer, which many people would see as truly introducing the prospect of Orwellian street surveillance, where our every move is recorded and stored by machines.

Although the problems of facial recognition by computer are far more formidable than for car number plates, experts believe it is only a matter of time before machines can reliably pull a face out of a crowd of moving people. If the police and security services can show that a national surveillance operation based on recording car movements can protect the public against criminals and terrorists, there will be a strong political will to do the same with street cameras designed to monitor the flow of human traffic. A major feature of the national surveillance centre for car numbers is the ability to trawl through records of previous sightings to build up an intelligence picture of a vehicle's precise whereabouts on the road network. However, the Home Office and police believe that the Big Brother nature of the operation can be justified on the basis of the technology's proven ability to catch criminals. "In simple terms criminals use vehicles. If you want to commit a crime, you're going to use a vehicle," said Frank Whiteley, the Chief Constable of Hertfordshire, who leads the project. " There is nothing secretive about it and we don't want it to be secret, because we want people to feel safer, to see that they are protected."

A 13-month pilot scheme between 2003 and 2004 found the performance of the police improved dramatically when they had access automatic number plate recognition (ANPR) cameras. Project Laser 2 involved 23 police forces using specially fitted vans with ANPR cameras linked to a police database. It led to a fivefold increase in the arrest rate for frontline officers. But these mobile units will constitute only a tiny proportion of the many thousands of ANPR cameras that by next year will be feeding more than 35 million number plate "reads" every day into the new national data centre at Hendon, north London, the same site as the Police National Computer. Mr Whiteley, chairman of the ANPR steering committee, said the intention eventually was to move from the "low thousands" of cameras to the "high thousands".

By March next year, most motorways, main roads, town centres and petrol station forecourts will be also covered. Some cameras may be disguised for covert operations but the majority will be ordinary CCTV traffic cameras converted to read number plates. "What we're trying to do as far as we can is to stitch together the existing camera network rather than install a huge number of new cameras," Mr Whiteley said.

Supermarkets are soon to agree a deal that will lead to all cars entering their garage forecourts having details of their number plates sent to Hendon. In return, the retailers will receive warning information about those drivers most likely to "bilk" - drive off without paying their bill. The plan beyond March 2006 - when the national data centre goes live - is to expand the capacity of the system to log the time, date and whereabouts of up to 100 million number plates a day. "In crude terms we're interested in between two and three per cent of all vehicles on the roads," Mr Whiteley said. "We can use ANPR on investigations or we can use it looking forward in a proactive, intelligence way. Things like building up the lifestyle of criminals - where they are going to be at certain times. We seek to link the criminal to the vehicle through intelligence. Vehicles moving on the roads are open to police scrutiny at any time. The Road Traffic Act gives us the right to stop vehicles at any time for any purpose. So criminals on public roads are vulnerable.

Are we feeling spied on yet?
