A first county-wide information-sharing system for local crime reduction partnerships targeting travelling, prolific shoplifters, has been launched in Hampshire.
Linked are business crime reduction partnerships (BCRPs) in the county’s four largest places – Portsmouth, Southampton, Winchester and Basingstoke. It enables the partnerships to pool their information, to identify offenders who are known in more than one of the partnerships – and hence can reasonably be suspected of being travelling, potentially prolific, thieves.
The four BCRPs all use the DISC online system for crime reduction partnerships, and the network is the first county-wide deployment of a Cross-DISC Data Sharing Group. Partnerships use their DISC systems to manage their own local partnerships and their banning schemes – but by linking together into a data sharing group, each DISC administrator can now check if any new offender in their own area is also known elsewhere. It also helps them put names to unidentified CCTV images.
Police stand to gain too, the software developers add. Hampshire Police have long supported the work of its BCRPs, for example by sharing its confidential intelligence with them.
Chief Insp Patrick Holdaway, who heads the Hampshire force’s business crime initiatives, says: “We work closely with local business communities and BCRPs, and share intelligence with them. Anything that helps identify criminals, particularly travelling or professional shoplifters is invaluable, and enables us to focus our resources where they can achieve the most benefit.
“My priority was around the legality of sharing our data through the new Data Sharing Group, and to ensure that the constabulary was not exposed. So we passed everything by the joint Hampshire Constabulary and Thames Valley Police Information Management Unit, who gave the scheme the green light.”
Chris Caesar, Crime Manager of Portsmouth BCRP, says: “We work on behalf of retailers throughout the city to identify and monitor low-level offenders and, if necessary, ban them from our members’ premises. Most of these offenders only operate locally, and many of them are well-known low-level thieves and banning them helps to protect our retailers from further theft – plus encourages the offenders to improve their behaviours.
“The new data-sharing network helps us identify offenders who we may become aware of at a local level – but who turn out to be travelling beyond our own immediate vicinity, and are therefore potentially prolific. Knowing who are ‘prolifics’ helps our retailers become more vigilant, and of course sharing that information with other Partnerships helps their retailers too. The very first time I used the new system I identified an offender known locally to us, who it turns out is known in one of the other Partnership areas. That’s impressive!”.
And Jane Bastock, Business Crime Reduction Officer at Winchester Business Improvement District, says: “Local low-level crime reduction is a priority for Winchester BID so we’re delighted we can share our intelligence with other partnerships across the county in this way. I used the system as soon as it became available and the facility is really excellent. It should help our members enormously.”
As for use: when the administrator of one of the partnerships in the group adds a new offender or incident into their local system they can click on a tool which automatically searches the combined databases of the participating partnerships for ‘matches’. Once a match has been found, the system enables the administrators to contact each other at a click, to check that the individual is indeed the same person and, if so, to agree to share that data between themselves.
Charlie Newman of Littoralis, the company behind DISC says: “The one-click matching process applies a highly complex search algorithm across the combined databases, and uses a large number of search criteria. Obviously the Offender’s name is important – if it’s available – but the matching compares build, gender, ethnicity, any other visual characteristics, the type of offences associated with the individuals and any other information that may be available including address, date of birth and so on. Not all this information is available of course, but the algorithm simply uses everything known about an offender to fetch a list of possible matches, ranked by similarity.
“The beauty of the system is that it doesn’t rely on still-unproven automated facial recognition systems which only work tolerably well with clearly lit, well-defined, full-face images – and most CCTV images are very far from that. The Cross-DISC Data Sharing system simply selects the top-20 best-matches and then enables the Administrator to visually compare the images to confirm that any of them are, indeed, the same individual.”
DISC is covering over 230 towns and city centres. Littoralis believes that Cross-DISC Data Sharing Groups will change the way low-level crimes, and the criminals, are identified, managed and brought to justice. Cross-DISC Data Sharing Groups have already been set up in London, but the new Hampshire group is the first to extend across a police force area. More Cross-DISC Data-Sharing Groups will follow in the next few months, Littoralis adds.
