Design and Implementation Aspects of Mobile Derived Identities
(Open Identity Summit 2017, 2017) Träder, Daniel; Zeier, Alexander; Heinemann, Andreas
With the ongoing digitalisation of our everyday tasks, more and more eGovernment services make it possible for citizens to take care of their administrative obligations online. This type of services requires a certain assurance level for user authentication. To meet these requirements, a digital identity issued to the citizen is essential. Nowadays, due to the widespread use of smartphones, mobile user authentication is often favoured. This naturally supports two-factor authentication schemes (2FA). We use the term mobile derived identity to stress two aspects: a) the identity is enabled for mobile usage and b) the identity is somehow derived from a physical or digital proof of identity. This work reviews 21 systems and publications that support mobile derived identities. One subset of the considered systems is already in place (public or private sector in Europe), another subset is subject to research. Our goal is to identify prevalent design and implementation aspects for these systems in order to gain a better understanding on best practises and common views on mobile derived identities. We found, that research prefers storing identity data on the mobile device itself whereas real world systems usually rely on cloud storage. 2FA is common in both worlds, however biometrics as second factor is the exception.
