On Thursday 1 February the world’s first ethical AI solution to support child safeguarding, CESIUM, was showcased at the College of Policing’s World of Data Event.

CESIUM, co-designed by Trilateral Research and Lincolnshire Police, was launched in November 2023, after six years of development and validation. Using state of the art sociotech methods, CESIUM harnesses the power of ethical AI to support safeguarding partnerships in their efforts to tackle child exploitation. Initial validation exercises saw 16 vulnerable children identified up to six months before the existing process, and three vulnerable children who would have otherwise been lost in the data.

Now garnering attention from across the field of policing and child safeguarding, representatives from Trilateral and Lincolnshire Police were invited to present their work to the College of Policing at the World Data Event.

A key focus of the event was the potential of AI in policing. There is not just a necessity for good data to help drive this, but to also understand the need for any AI in policing, and in the wider public sector, to be thoroughly ethically assessed. Levels of data literacy within the police were also discussed as a stepping stone to understanding the potential of data and AI in policing.

CESIUM was presented by Detective Inspector James Hoyes from Lincolnshire Police and Gavin Day from Trilateral Research. Explaining how CESIUM can highlight vulnerability across agencies and force boundaries in an ethical and explainable way, they gave detailed insight into how it can significantly enhance safeguarding capabilities and identify intervention opportunities for safeguarding professionals.

On CESIUM being showcased at the event, Mandy Kaur, Digital Policing Programme (DPP) Strategic Work Stream Lead – Legal Exploitation of Data and Evidence, College of Policing, said,


The College of Policing have put forward Lincolnshire Police for using a predictive analytics platform – using advanced analytics (CESIUM) to see if the Biometrics and Forensics Ethics Group (BFEG) can be a national independent data ethics panel that forces and law enforcement can use. The College of Policing are working with partners to evaluate the process currently.



On the significance of the introduction of ethical AI to policing, Detective Inspector James Hoyes said,


CESIUM is an exciting tool to help us improve our identification of the most vulnerable people in Lincolnshire. The near time ability to review where risk has increased or to identify risk for the first time will simplify and speed up our safeguarding capability.



On the importance of a responsible AI solution being showcased at this event, Gavin Day, Client Relationship Lead for Trilateral said,


The ongoing theme of the day, as well as the ethics of AI, was that forces are doing things in 43 different ways, using expensive technology that doesn’t always provide the best results. There was a real buzz in the room as we explained how CESIUM can be used across force boundaries answering the question of how the police can merge solutions, in an ethical, explainable way that improves information sharing and highlights vulnerability, locally, regionally and nationally.
