    Real World Data - Technologies, Research Questions and Applications - Study in Cooperation - School of Business & School of Life Science
    (Fachhochschule Nordwestschweiz FHNW, 2019) Grimberg, Frank; Asprion, Petra; Schneider, Bettina; Miho, Enkelejda; Babrak, Lmar; Habbabeh, Ali
    In this research report of the University of Applied Sciences and Arts Northwestern Switzerland (FHNW), a classification of ‘Real World Data’ into the research landscape takes place. In addition, an identification of the still open research questions is done based on the fundamental principles and properties. The manifold potential of this relatively new data set is illustrated by a presentation of the already existing but also conceivable future application possibilities. Finally, the contribution of the FHNW, based on its specific competencies, to the further application of the dataset is shown.

    Touching space: distributed ledger technology for tracking and tracing certificates
    (2023) Moriggl, Pascal; Asprion, Petra; Schneider, Bettina; Scherb, Christopher; Bui, Tung X.
    Components built into space vehicles and equipment (space products) must meet different regulatory requirements; in detail, each component must be certified and sustainably traceable at all times. Space engineers have expressed the need for an interoperable system to collect, manage and route certifications for components, parts and materials that go into space products. The lack of a unified approach in the European space industry is a challenge for companies involved in product development. This research proposes an open-source, secure, fast and distributed ledger technology (DLT) based solution that fits into any IT environment and is well adapted to the needs of manufacturing companies in the space sector. The results show that a blockchain-based solution based on ‘Hyperledger Fabric’ combined with the InterPlanetary File System is viable. The results can guide other researchers and practitioners to consider DLTs when changing their certification management paradigm with suppliers, customers and auditors.

    Human-centered artificial intelligence: a multidimensional approach towards real world evidence
    (2019) Schneider, Bettina; Asprion, Petra; Grimberg, Frank; Filipe, Joaquim; Smialek, Michal; Brodsky, Alexander; Hammoudi, Slimane
    This study indicates the significance of a human-centered perspective in the analysis and interpretation of Real World Data. As an exemplary use-case, the construct of perceived ‘Health-related Quality of Life’ is chosen to show, firstly, the significance of Real World Data and, secondly, the associated ‘Real World Evidence’. We settled on an iterative methodology and used hermeneutics for a detailed literature analysis to outline the relevance and the need for a forward-thinking approach to deal with Real World Evidence in the life science and health care industry. The novelty of the study is its focus on a human-centered artificial intelligence, which can be achieved by using ‘System Dynamics’ modelling techniques. The outcome – a human-centered ‘Indicator Set’ can be combined with results from data-driven, AI-based analytics. With this multidimensional approach, human intelligence and artificial intelligence can be intertwined towards an enriched Real World Evidence. The developed approach considers three perspectives – the elementary, the algorithmic and – as novelty – the human-centered evidence. As conclusion, we claim that Real World Data are more valuable and applicable to achieve patient-centricity and personalization if the human-centered perspective is considered ‘by design’.

    Perceptions and misconceptions of blockchain: the potential of applying threshold concept theory
    (2022) Schneider, Bettina; Azan, Wilfrid
    Blockchain is a technology of increasing importance. It is difficult to build a thorough understanding of blockchain as it relies on multiple abstract and technological building blocks. Therefore, it is not surprising that a number of misconceptions circulate on the topic of blockchain. This paper filters and categorizes existing research on people’s perceptions of blockchain technology and misconceptions. The identified gap in addressing and overcoming misconceptions leads to the theory of threshold concepts. The fundamentals and potentials of the approach in the field of blockchain are elaborated. The paper ends with a call for future research in this direction.

    Decentralized autonomous organizations – Evolution, challenges, and opportunities
    (2022) Schneider, Bettina; Ballesteros, Ruben; Moriggl, Pascal; Asprion, Petra; Bork, Dominik; Barat, Souvik; Asprion, Petra; Marcelletti, Alessandro; Morichetta, Andrea; Schneider, Bettina; Kulkarni, Vinay; Breu, Ruth; Zech, Philipp
    A decentralized autonomous organization (DAO) is an emerging entity facilitated through blockchain technology. It operates under the principle of a decentralized governance structure void of hierarchical leadership, and decisions are made based on community consensus. As DAO and its mechanisms are still in an early stage, its potential evolution and future influence on enterprises remain unclear. This work elaborates on this emerging type of organization through a literature review and case studies of DAOs to demonstrate the current state of the art. The findings presented include a brief discussion of the technology that facilitates these organizations. Additionally, advancements and the common characteristics of existing DAOs are presented. Examining current and defunct DAOs revealed the challenges these organizations should address to reach their full potential in future application areas. Finally, it is concluded which organizations and industries could most likely benefit from the DAO concept in future.

    Post-quantum cryptography: an introductory overview and implementation challenges of quantum-resistant algorithms
    (2022) Käppler, Sherdel; Schneider, Bettina; Hinkelmann, Knut; Gerber, Aurona
    Cryptographic algorithms are an essential measure to ensure confidentiality and integrity of internet communication. The development of quantum computers (QCs) and their potential to utilize Shor’s Law, is increasingly recognized as a threat to asymmetric cryptography. In response, post-quantum cryptography (PQC) is gaining prominence as a notable field of research aiming to standardize quantum resistant algorithms before the operational usage of QCs. This paper is addressed to people with preliminary knowledge in the field of cryptography and QC. Based on a literature review, the authors provide an overview of challenges faced by the research community and elaborate the advancements in addressing post-quantum threats. A migration strategy from classical cryptosystems to PQC systems is in development, but obstacles such as time constraints and improper implementation complicate the process. Full implementation could take a decade or more. Until then, our paper aims to create awareness for potential challenges when transitioning towards PQC. As categorization scheme for these potential obstacles, we refer to a well- established model in cybersecurity – the McCumber Cube. Conclusions embrace preparing for risks of improper implementation and deriving a multi-step migration. Special attention is expected to be needed for data migration of existing data sets. As a request for future research in PQC, the authors identified the process of implementing post-cryptography standards, e.g., from the National Institute of Standards and Technology (NIST), and an assessment of the perceived readiness of industry to adapt.
