About the work

Why the work is being done
The aim of CAID is to continue to provide UK law enforcement with an image database and associated tools to aid investigations into indecent images of children. Over the next 5 years, the CAID Transformation Programme aims to expand CAID in line with policing priorities and provide new capabilities such as automated tools to examine and categorise large volumes of images and videos and new AI capabilities to help investigators safeguard victims. The improvements being made to CAID will to help streamline the investigation and prosecution of offenders and help to safeguard children from abuse.
Problem to be solved
The CAID programme requires a service to deliver the next stage of CAID development and the ongoing operation of the CAID system. Work will include architecting new infrastructure, designing the integration of tools, capturing requirements and designing new processes, project management and business change support.
Delivery of the programme will require management of the approved suppliers, coordination with Law Enforcement users, engagement with stakeholders and collaboration with Home Office team members in roles across all functions of the programme. There is also a need to work with related policing and Home Office technology programmes with the aim of reusing common services where these fit with CAID requirements.
Who the users are and what they need to do
The users of CAID include UK Police Forces, the National Crime Agency and the Internet Watch Foundation.

Law Enforcement Organisations need to identify, categorise and share illegal images and videos of children so they can safeguard victims of child sexual exploitation and prosecute offenders. They need to enhance their ability to carry out these activities and increase their capacity to support more investigations as offender behaviour changes due to the changing nature of technology.
