Prisoners 'to be chipped like dogs'

Ministers are planning to implant "machine-readable" microchips under the skin of thousands of offenders as part of an expansion of the electronic tagging scheme that would create more space in British jails.

Amid concerns about the security of existing tagging systems and prison overcrowding, the Ministry of Justice is investigating the use of satellite and radio-wave technology to monitor criminals.

But, instead of being contained in bracelets worn around the ankle, the tiny chips would be surgically inserted under the skin of offenders in the community, to help enforce home curfews. The radio frequency identification (RFID) tags, as long as two grains of rice, are able to carry scanable personal information about individuals, including their identities, address and offending record.

Professionals in the criminal justice system maintain that the present system is 95 per cent effective. Radio frequency identification (RFID) technology is unproven. The technology is actually more invasive, and carries more information about the host. The devices have been dubbed "spychips" by critics who warn that they would transmit data about the movements of other people without their knowledge.

Consumer privacy expert Liz McIntyre said a colleague had already proved he could "clone" a chip. "He can bump into a chipped person and siphon the chip's unique signal in a matter of seconds," she said.

One company plans deeper implants that could vibrate, electroshock the implantee, broadcast a message, or serve as a microphone to transmit conversations. "Some folks might foolishly discount all of these downsides and futuristic nightmares since the tagging is proposed for criminals like rapists and murderers," Ms McIntyre said. "The rest of us could be next."
