Who is the Better Operator of an IdentityWallet Prioritised by the User?: A Quantitative Survey between State and Company

This paper presents the results of an online survey based on a developed concept that enables the storage of multiple digital identities in one app. Users manage these identities in the so-called Identity Wallet independently and decide which data should be sent to any external service. As previous usability studies indicate that the operator of the Identity Wallet is decisive for user trust in such technologies, a quantitative study was conducted with 306 people. The participants were asked to rank possible operators (e.g. state, open source community projects, known company, etc.) in order of their preference. The results show that, on average, a private company is favoured as the operator. However, if the operator that was named first by most participants is considered, then this is the state.
