“…However, private sector firms optimize primarily for shareholder value and not for PV, even if this method is currently being questioned (Weigl et al, 2022). Yet, modern challenges (e.g., the emergence of digital identities and the need for a radical change in how society manages natural resources) require new joint approaches (Rieger et al, 2022;Weigl et al, 2022). Still, eGovernment can leverage private sector innovation, enabling outside-in transformations (Klievink et al, 2016).…”

Governments across the globe are facing pressure to increase the speed of their digital transformation to meet the needs of the digital society while fulfilling their primary task of delivering public value. While researchers agree on the importance of the public sector for public value creation, recently, more and more studies have recognized the criticality of collaboration between the public and private sectors for successful public value creation. In our research, we conduct a qualitative survey. We examine the idea of collaboration between the public and the private sectors in more detail and add the citizens' perspective. We highlight the need for joint forces for optimal public value creation, identify ways to achieve this, and determine what digital technologies can support this process.

Self-sovereign identity represents a novel phenomenon aiming to innovate how entities interact with, manage, and prove identity-related information. As with any emerging phenomenon, user acceptance represents a major challenge for the adoption of Selfsovereign identity. Since previous initiatives for digital identity management solutions have not been successfully adopted while at the same time their benefits are largely driven by network effects, user acceptance research is of particular importance for Self-sovereign identity. Therefore, we investigate the user acceptance of Self-sovereign identity by conducting a qualitative interview study. We contribute novel variables to existing theory and offer guidelines for building Self-sovereign identity systems.

“…Our approach hence targets polls where there is cryptographic evidence for the answers, e.g., a digital ID card signed by a government, digital diplomas issued by a certified university, or COVID-19 immunity passports certified by pharmacies or doctors. Such attestations are considered, for instance, in the European digital wallet initiative [15,46,48]. In this context, it is particularly helpful that the digital certificates involved in the many implementations of digital wallets are in fact anonymous credentials [7,50,52], which allows us to extract a user's attribute values without revealing strongly correlating information.…”

Analyses that fulfill differential privacy provide plausible deniability to individuals while allowing analysts to extract insights from data. However, beyond an often acceptable accuracy tradeoff, these statistical disclosure techniques generally inhibit the verifiability of the provided information, as one cannot check the correctness of the participants' truthful information, the differentially private mechanism, or the unbiased random number generation. While related work has already discussed this opportunity, an efficient implementation with a precise bound on errors and corresponding proofs of the differential privacy property is so far missing. In this paper, we follow an approach based on zero-knowledge proofs (ZKPs), in specific succinct non-interactive arguments of knowledge, as a verifiable computation technique to prove the correctness of a differentially private query output. In particular, we ensure the guarantees of differential privacy hold despite the limitations of ZKPs that operate on finite fields and have limited branching capabilities. We demonstrate that our approach has practical performance and discuss how practitioners could employ our primitives to verifiably query individuals' age from their digitally signed ID card in a differentially private manner.
