Interoperability In the New Digital Identity Infrastructure



This paper maps out multiple dimensions of interoperability in the emerging digital identity management infrastructure, with a view to promoting openness in this infrastructure. The paper provides a background to the infrastructure; an explanation of components, items exchanged, and interconnection flows; an account of interoperability at various levels; a look at the costs and benefits of interoperability; and a brief consideration of factors that influence interoperability and innovation, such as the market, law, and self-regulation. Because this technology is still developing, the paper seeks to offer a snapshot of the current landscape with a view to promoting discussion about the future.
