SAIL architecture. This diagram shows the SAIL databank system and the controls in place for data acquisition and utilisation, with an indication of the roles carried out by each party. Beginning at the base of the diagram, SAIL has formal agreements with data providers to provide their data to the databank in accordance with Information Governance. The commonly-recognised identifiers are anonymised at NWIS, who provide a trusted third party service to SAIL. Further processes of masking and encryption are carried out at SAIL, and the SAIL databank is constructed. From the top of the diagram, requests to use the data are reviewed by SAIL and an independent Information Governance Review Panel (IGRP) to assess compliance with Information Governance before access can be allowed. Once this is agreed, a data view is created by SAIL staff, and access to this view can be made available via the SAIL Gateway. For this to happen, further data transformations are carried out to control the risk of disclosure, and the data user signs an access agreement for responsible data utilisation, in accordance the specifications of the IGRP to comply with Information Governance.
