Air passengers 'could be tagged'.
By Rebecca Morelle
Electronically tagging passengers at airports could help the fight
against terrorism, scientists have said.
The prototype technology is to be tested at an airport in Hungary, and
could, if successful, become a reality "in two years".
The work is being carried out at a new research centre, based at
University College London, set up to find technological solutions to crime.
Other projects include scanners for explosives and dirty bomb radiation.
Dr Paul Brennan, an electrical engineer, is leading the tagging project,
known as Optag.
He said: "The basic idea is that airports could be fitted with a network
of combined panoramic cameras and RFID (radio frequency ID) tag readers,
which would monitor the movements of people around the various terminal
The plan, he said, would be for each passenger to be issued with a tag
He said: "In our system, the location can be detected to an accuracy of
1m, and video and tag data could be merged to give a powerful
