UK digital ID may be dead, but its legacy IT problem lives on

The UK's abandoned national digital ID scheme faced substantial challenges due to legacy government systems, according to the National Audit Office (NAO). The NAO released a review of the digital identity landscape, highlighting the importance of addressing these legacy systems when considering future attempts at a government-wide system.

Digital identity is not a singular product or technology, but rather a complex system involving services, credentials, standards, providers, and governance arrangements across both public and private sectors.

The NAO emphasized that digital identity is most effective when it is found to be useful and beneficial to people in their everyday lives, accompanied by robust security and privacy measures. Gareth Davies, head of the NAO, noted that while the government has cancelled the digital ID scheme, the question of how individuals can conveniently and securely prove their identity in a digital world remains pertinent.

The report identified inconsistent data standards and multiple ways of representing the same person across different systems as barriers to introducing digital ID across government. These inconsistencies make it difficult to link data and limit the ability to integrate data across various services.

To overcome these issues, any future government-wide digital identity proposal should clearly define its objectives and delivery model, and explain how it would address the longstanding constraints posed by legacy systems and fragmented data.
