Our approach on the technology is straightforward. When the Bill has passed through Parliament, we intend to conduct trials of the technology, including small-scale tests, database tests and large-scale testing during roll-out. There has been a lot of concern about biometric identity cards, especially those using iris recognition, so I draw the House's attention to a report published earlier this week by the university of Cambridge computer laboratory. Its conclusion and recommendations indicate clearly and categorically:
"Iris recognition can be reliably used on a national basis in an Identity Cards scheme, including the capability for exhaustive iris code comparisons to detect multiple identities, if the decision policy employs a threshold criteria"— it then sets out some technical details. These issues can thus be resolved.
