Design and Implementation Aspects of Mobile Derived Identities

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 met these requirements, a digital identity issued to the citizen is essential. Nowadays, due to the widespread of smartphones, often mobile user authentication is favoured. This naturally supports for 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 that support mobile derived identities. One subset of the considered systems are already in place (public or private sector in Europe), another subset belongs to research. We found that research prefers the storage of identity data on the mobile device itself whereas real world systems rely on cloud storage. 2FA is common in both worlds, however biometrics as second factor is rather the exception.
