The United States wants to recruit Britain, Canada and other countries for its new system of sharing biometric data on terrorists and criminals, a British newspaper reported Tuesday.

The FBI said the new security database, called "Server in the Sky," was still being designed, the Guardian reported.

Once active, it would enable countries to search and swap data such as fingerprints, genetic information and iris scans on some of the world's most wanted criminals.
The FBI said the database would hold information on "the world's worst of the worst individuals," according to the newspaper.

The Guardian said other countries, including Canada, Australia and New Zealand, had been approached to participate in the project.

Britain's National Police Improvement Agency, which has discussed the project with the FBI, said it was too early to say whether Britain would participate.

"There was a discussion last year," a spokesman for the agency said, speaking on condition of anonymity in line with agency policy. "That was it. There [are] no specific discussions on timescales or how it would be delivered. We've got no plans to do anything at this time."

Britain's Home Office and London's Metropolitan Police said they were aware of the project but refused to go into any detail.

The FBI did not immediately return a call requesting comment.

Britain has already agreed to give its European allies access to much of its biometric information. EU nations completed a plan last year to share databases containing fingerprints, genetic information and license plate numbers.

That data-sharing deal, known as the Pruem Treaty, is intended to automate information-sharing and do away with time-consuming data requests. The system is online in Germany, Spain, France, Belgium, Finland, Slovenia, the Netherlands, Austria and Luxembourg.

Last year, the German interior minister suggested the measures could be extended to the U.S. as part of a worldwide effort to track terror suspects and wanted criminals.

Sound like a good idea?
