Software produced by the GB Group is helping both the police and the UK government to track people's last known address more efficiency, the company claims.

The Accelerator IQ uses a number of databases to cross-reference address to provide the most current and up-to-date information, GB Group states.

It also adds that it has been used in some recent high-profile police cases, such as the conviction of Steve Wright who was convicted of the murder of five women in Ipswich.

Phil Boswell, detective inspector at Suffolk police, states: "Accurate intelligence gathering and address verification is key in an investigation of any size, but on the scale we experienced here it made officer time far more efficient and made a vital difference."

Last month, GB Group that another of its tracking technologies, URU ID, was being used by e-service provider The Exchange.

URU ID had been developed by GB Group and BT in a joint venture.
