Current know-your-customer (KYC) processes at financial institutions are inefficient, costly, and – in many cases – inconvenient for customers. Among the often-mentioned solutions to improve KYC processes are blockchains and self-sovereign identity (SSI). However, the literature provides little guidance on those technologies with regard to regulato...

An organization’s ability to develop Machine Learning (ML) applications depends on its available resource base. Without awareness and understanding of all relevant resources as well as their impact on the ML lifecycle, we risk inefficient allocations as well as missing monopolization tendencies. To counteract these risks, the study develops a frame...

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 Self-sovereign identity. Since previous initiatives for digital identity management solutions have not...

The digital transformation of the medical sector requires solutions that are convenient and efficient for all stakeholders while protecting patients’ sensitive data. One example that has already attracted design-oriented research are medical prescriptions. However, current implementations of electronic prescription management systems typically crea...

The labeling of electricity is considered an important mechanism to differentiate renewable power generation and, thus, to incentivize the expansion of green energy. However, today's systems for documenting and trading green energy certificates suffer from multiple challenges. These could be addressed by a digital solution that holistically collect...

Information Systems research acknowledges the importance of identifying requirements to ensure the artifact’s relevance. However, many research articles addressing blockchain technology for e-government capture the requirements that need to be fulfilled only implicitly by defining system objectives or evaluation criteria. Furthermore, focusing on s...

Information systems research emphasizes that blockchain requires trust in the technology itself. However, we lack knowledge on the applicability of established trust cues to blockchain technology. Thus, this paper’s objec-tive is to empirically evaluate the effectiveness of several established IS trust formation factors on end user trust. We do so...

Due to blockchains' intrinsic transparency and immutability, blockchain-based applications are challenged by privacy regulations, such as the EU General Data Protection Regulation. Hence, scaling blockchain use cases to production often fails to owe to a lack of compliance with legal constraints. As current research mainly focuses on specific use c...

Within the last decades, our world has changed even faster and more fundamentally than before due to technical progress. Digital technologies influence many areas of our social life. At the same time, privacy and security issues in the digital environment are constantly coming to the foreground. These aspects have become increasingly important, esp...

Due to a steeply growing number of energy assets, the increasingly decentralized and segmented energy sector fuels the potential for new digital use cases. In this paper, we focus our attention on the application field of asset logging, which addresses the collection, documentation, and usage of relevant asset data for direct or later verification....

The ongoing digital transformation of the medical sector requires solutions that are convenient and efficient for all stakeholders while protecting patients' sensitive data. One example involving both patients and health professionals that has already attracted design-oriented research are medical prescriptions. However, current implementations of...

In response to weaknesses of current network security solutions, the zero-trust model follows the idea that no network – whether internal or external – is trustworthy. The concept of zero-trust is enjoying increasing attention in both research and practice due to its promise to fulfil complex new network security requirements. Despite zero-trust's...

Bei der Blockchain-Technologie handelt es sich um ein dezentrales elektronisches Register für digitale Transaktionen. Zu den Eigenschaften der Technologie zählen u. a. eine hohe Manipulationsresistenz, welche Vertrauen in digitale Daten erzeugen kann, sowie die Möglichkeit, Prozesse und Transaktionen, ohne Intermediär abzuwickeln. Diese besonderen...

Innerhalb der letzten Dekaden hat sich unsere Welt durch technologischen Fortschritt noch schneller und fundamen-taler verändert als zuvor. Viele Teilbereiche unseres gesellschaftlichen Lebens werden heute durch digitale Technolo-gien bestimmt. Dabei rücken auch immer wieder Themen der Privatsphäre und Sicherheit im digitalen Umfeld in den Vordergr...

In 2020, the world has witnessed an unprecedented global pandemic with COVID-19. It has led nations to take measures that have an enormous impact on individuals, society, and the economy. Researchers and practitioners responded rapidly, evaluating the opportunities to capitalize on technology for tackling the associated challenges. We investigate t...
