    Privacy and availability needs regarding user preferences for Smart Availability Assistant – towards a digitally enabled work life balance
    (Open Identity Summit 2020, 2020) Saternus, Zofia
    The use of communication technologies (CTs) enables blurring the traditional boundaries between work and private life. Many employers are worried about this situation and addressed those issues with different technological and organizational approaches. The goal of our research is to introduce improved enterprise availability management by developing an employee-friendly technological solution that actually reflects the variety of employees’ availability needs. Due to the overall aim of broadening and bridging research on an availability management, results of a quantitative study (N=821) insights into the management of individuals’ availability and key requirements regarding the development of a Smart Availability Assistant. In general, it became apparent that to appropriately design this kind of smart assistant we must not only recognize the heterogeneity of peoples’ availability preferences but also identify and meet employees’ privacy expectations by use of a Smart Availability Assistant.

    Agent-based Models as a Method to Analyse Privacy-friendly Business Models in an Assistant Ecosystem
    (Open Identity Summit 2020, 2020) Kubach, Michael; Fähnrich, Nicolas; Mihale-Wilson, Cristina
    Various projects and initiatives strive towards designing privacy friendly open platforms and ecosystems for digital products and services. However, besides mastering technical challenges, achieving economic viability and broad market success has so far proven to be difficult for these initiatives. Based on a publicly funded research project, this study focuses on the business model design for an open digital ecosystem for privacy friendly and trustworthy intelligent assistants. We present how the agent-based modelling technique can be employed to evaluate how business models perform in various constellations of an open digital ecosystem. Thus, our work relates to the strategic choice of suitable business models as an important success factor for privacy and security-relevant technologies.

    Identity Management as a target in cyberwar
    (Open Identity Summit 2020, 2020) Fritsch, Lothar
    This article will discuss Identity Management (IdM) and digital identities in the context of cyberwar. Cyberattacks that target or exploit digital identities in this context gain leverage through the central position of IdM digital infrastructures. Such attacks will compromize service operations, reduce the security of citizens and will expose personal data - those of military personell included. The article defines the issue, summarizes its background and then discusses the implications of cyberwar for vendors and applicants digital identity management infrastructures where IdM is positioned as a critical infrastructure in society.

    Accountable Trust Decisions: A Semantic Approach
    (Open Identity Summit 2020, 2020) Schlichtkrull, Anders; Mödersheim, Sebastian
    This paper is concerned with the question of how to obtain the highest possible assurance on trust policy decisions: when accepting an electronic transaction of substantial value or significant implications, we want to be sure that this did not happen because of a bug in a policy checker. Potential bugs include bugs in parsing documents, in signature checking, in checking trust lists, and in the logical evaluation of the policy. This paper focuses on the latter kind of problems and our idea is to validate the logical steps of the trust decision by another, complementary method. We have implemented this for the Trust Policy Language of the LIGHTest project and we use the completely independently developed FOL theorem prover RP_X as a complementary method.

    On the diffusion of security behaviours
    (Open Identity Summit 2020, 2020) Kurowski, Sebastian; Roßnagel, Heiko
    Security behaviour has been researched from a variety of theoretical lenses, however a clear picture on the factors that foster secure behaviour is still missing. This contribution uses the diffusion of innovations theory and applies it to four exemplary security behaviours to identify how it can explain the uptake of each behaviour. In contrast to many other approaches, it focuses on the behaviour itself, not the behaving individual. We are able to show differences in the uptake of idealized security behaviours. A perceived relative advantage positively impacts the uptake of a behaviour, however this advantage seems rarely to be motivated by a perceived risk. Risk only seems to play a minor role for the diffusion of security behaviours. Additionally, the relative advantage does not seem to be a necessity for the diffusion of a behaviour. If the other properties namely compatibility, triability, observability, and low complexity of a behaviour are adequately fulfilled a successful diffusion is still possible.

    Criteria for trustworthy digital transactions - Blockchain/DLT between eI-DAS, GDPR, Data and Evidence Preservation
    (Open Identity Summit 2020, 2020) Kusber, Tomasz; Schwalm, Steffe; Shamburger, Kalinda; Korte, Ulrike
    With the help of eIDAS [Re14], legislators have created a resilient framework in EU and EFTA to place trustworthy digital transactions more and more in the centre of business relationships. The regulated use of the trust services (e.g. qualified electronic signature or seal etc.) as well as that of the secure electronic identities provides a solid foundation for the advancement of digitization. The adequate evidence of electronic records as long as they are needed is a critical success-factor for trustworthy digital transactions. The trustworthiness of the transactions must be based on compliance with the basic values of authenticity, integrity, reliability, availability, confidentiality and transferability. After a first hype there are increasingly more considerations also in regulated industries to use DLT for digital processes which have to be accountable. In order to make them evident and to fulfil documentation requirements it is necessary that DLT fulfils the legal framework and prior art based on defined criteria for trustworthy digital transactions. This paper focuses on the challenges and requirements for utilisation of DLT for trustworthy digital processes including long-term preservation.

    Digital and mobile identities
    (Open Identity Summit 2020, 2020) Funke, Holger
    In this paper current developments in mobile identities are described. A scalable architecture, standard future-proven technologies such as ISO/IEC 23220 and a Cryptographic Service Provider build the framework for secure, failsafe and large deployments. The building blocks specified in ISO/IEC 23220 deliver a framework that can be easily used for identities stored on secure devices such as smartphones. This paper lists a selection of outstanding projects using mobile and digital identities in the field of mobile ID. The focus is on Digital Travel Credentials (DTC) which are currently specified by the International Civil Aviation Organization (ICAO).

    Self-sovereign and Decentralized identity as the future of identity management?
    (Open Identity Summit 2020, 2020) Kubach, Michael; Schunck, Christian H.; Sellung, Rachelle; Roßnagel, Heiko
    Blockchain-based Self-sovereign and Decentralized identity approaches are seen by many as the future of identity management. These solutions are supposed to finally bring universally usable, trustworthy, secure, and privacy friendly digital identities for everyone and all use cases. This paper first presents the promises of this technological app

    IdToken: a new decentralized approach to digital identi-ty
    (Open Identity Summit 2020, 2020) Talamo, Edoardo; Pennacchi, Alma
    The ability to store and share digital data offers benefits that the digitization of information has become a growing trend but has raised questions about the security of personal data. There have been countless high-profile hacks and personal information leaks. Furthermore users don’t (and shouldn’t) always trust an external server of a third party to store their personal data. Blockchain tries to offer a compelling solution to the problem of combining accessibility with privacy and security. Records can be held securely, using end-to-end encryption, and yet openly authenticated so that data can still be trusted as reliable. This project goes deeper in this solution thanks to an innovative idea and development of a new kind of blockchain non fungible token specifically created to store and manage digital identities and sensible data. It has the potential to resolve issues blockchain alone was starting to approach and improves security, privacy and accessibility.
