    This Open Access book shows how value sensitive design (VSD), responsible innovation, and comprehensive engineering can guide the rapid development of technological responses to the COVID-19 crisis. Responding to the ethical challenges of data-driven technologies and other tools requires thinking about values in the context of a pandemic as well as in a post-COVID world. Instilling values must be prioritized from the beginning, not only in the emergency response to the pandemic, but in how to p…Read more

    Sovereignty, privacy, and ethics in blockchain-based identity management systems
    Ethics and Information Technology 23 (3): 239-252. 2020.
    Self-sovereign identity solutions implemented on the basis of blockchain technology are seen as alternatives to existing digital identification systems, or even as a foundation of standards for the new global infrastructures for identity management systems. It is argued that ‘self-sovereignty' in this context can be understood as the concept of individual control over identity relevant private data, capacity to choose where such data is stored, and the ability to provide it to those who need to …Read more

    The moral significance of blockchain technologies is a highly debated and polarised topic, ranging from accusations that cryptocurrencies are tools serving only nefarious purposes such as cybercrime and money laundering, to the assessment of blockchain technology as an enabler for revolutionary positive social transformations of all kinds. Such technological determinism, however, hardly provides insights of sufficient depth on the moral significance of blockchain technology. This thesis argues r…Read more

    The Ethical Limits of Blockchain-Enabled Markets for Private IoT Data
    Philosophy and Technology 33 (3): 411-432. 2020.
    This paper looks at the development of blockchain technologies that promise to bring new tools for the management of private data, providing enhanced security and privacy to individuals. Particular interest present solutions aimed at reorganizing data flows in the Internet of Things architectures, enabling the secure and decentralized exchange of data between network participants. However, as this paper argues, the promised benefits are counterbalanced by a significant shift towards the properti…Read more

    Fictions and frictions: Promises, transaction costs and the innovation of network technologies
    with Udo Pesch
    Social Studies of Science 49 (2): 264-277. 2019.
    New network technologies are framed as eliminating ‘transaction costs’, a notion first developed in economic theory that now drives the design of market systems. However, the actual promise of the elimination of transaction costs seems unfeasible, because of a cyclical pattern in which network technologies that make that promise create processes of institutionalization that create new forms transaction costs. Nonetheless, the promises legitimize the exemption of innovations of network technologi…Read more

    Rethinking Trust in the Internet of Things
    In R. Leenes, R. Van Brakel, S. Gutwirth & P. De Hert (eds.), Data Protection and Privacy: The Internet of Bodies. pp. 203-230. 2018.
    This chapter argues that the choice of trust conceptualisations in the context of consumer Internet of Things (IoT) can have a significant impact on the understanding and implementations of a user’s private data protection. Narrow instrumental interpretations of trust as a mere precondition for technology acceptance may obscure important moral issues such as malleability of user’s privacy decisions, and power imbalances between suppliers and consumers of technology. A shift of focus in policy pr…Read more

    Blockchain Technology as an Institution of Property
    Metaphilosophy 48 (5): 666-686. 2017.
    This paper argues that the practical implementation of blockchain technology can be considered an institution of property similar to legal institutions. Invoking Penner's theory of property and Hegel's system of property rights, and using the example of bitcoin, it is possible to demonstrate that blockchain effectively implements all necessary and sufficient criteria for property without reliance on legal means. Blockchains eliminate the need for a third-party authority to enforce exclusion righ…Read more
