Centralised validation in digital forensics
Designing scalable approaches to validation to ensure forensic methods are reliable and consistent across organisations.
Validation is essential to ensure that forensic methods are fit for purpose and reliable in practice. Without appropriate validation against reference data, the limitations and constraints of a method will not be fully understood.
In digital forensics, this presents particular challenges due to the rapid pace of change in devices, applications, and data encountered in operational work.
This project involved contributing subject-matter expertise on a national programme to develop a pilot centralised validation service for digital forensics.
The work focused on validating commonly used tools for capturing and analysing data from mobile devices, and on developing large, representative test datasets to support this process.
The project highlights the importance of ensuring that validation approaches remain effective and scalable under real-world conditions.
A central repository of validation materials was also designed to support sharing across UK police forces, enabling validation to be conducted once and for the benefit of many.
