International interoperability has been cited as the most significant barrier to introducing digital IDs in the UK, according to government-commissioned research.
Last year, the Department for Science, Innovation and Technology (DSIT) via its Office for Digital Identities and Attributes, commissioned research to provide evidence on the feasibility of introducing digital IDs for cross-border use.
The project was launched to guide policymakers as the government continues to explore how digital IDs can be implemented and issued to British citizens in the form of e-passports, drivers licences and more.
The research project, which queried 39 companies providing digital verification services, found that the vast majority of respondents (79%) said regulatory diversity and disparate systems internationally was the largest barrier.
It was largely agreed that if any cross-border digital IDs were to be issued, there would have to be significant harmonisation between national frameworks. Over half (57%) of respondents said they wanted to see a clear international standard set and recognised for the technology.
Recommendations that came up included the establishment of mutual recognition agreements with international partners, enabling private sector/industry involvement in policy-making; issuing credentials, attributes and wallets; and providing clarity and guidance on legal and liability implications of cross-border digital identity use.
