    Combined automotive safety and security pattern engineering approach

    Automotive systems will exhibit increased levels of automation as well as ever tighter integration with other vehicles, traffic infrastructure, and cloud services. From safety perspective, this can be perceived as boon or bane - it greatly increases complexity and uncertainty, but at the same time opens up new opportunities for realizing innovative safety functions. Moreover, cybersecurity becomes important as additional concern because attacks are now much more likely and severe. However, there is a lack of experience with security concerns in context of safety engineering in general and in automotive safety departments in particular. To address this problem, we propose a systematic pattern-based approach that interlinks safety and security patterns and provides guidance with respect to selection and combination of both types of patterns in context of system engineering. A combined safety and security pattern engineering workflow is proposed to provide systematic guidance to support non-expert engineers based on best practices. The application of the approach is shown and demonstrated by an automotive case study and different use case scenarios.EC/H2020/692474/EU/Architecture-driven, Multi-concern and Seamless Assurance and Certification of Cyber-Physical Systems/AMASSEC/H2020/737422/EU/Secure COnnected Trustable Things/SCOTTEC/H2020/732242/EU/Dependability Engineering Innovation for CPS - DEIS/DEISBMBF, 01IS16043, Collaborative Embedded Systems (CrESt

    Towards Systemic Evaluation

    Problems of conventional evaluation models can be understood as an impoverished ‘conversation’ between realities (of non-linearity, indeterminate attributes, and ever-changing context), and models of evaluating such realities. Meanwhile, ideas of systems thinking and complexity science—grouped here under the acronym STCS—struggle to gain currency in the big ‘E’ world of institutionalized evaluation. Four evaluation practitioners familiar with evaluation tools associated with STCS offer perspectives on issues regarding mainstream uptake of STCS in the big ‘E’ world. The perspectives collectively suggest three features of practicing systemic evaluation: (i) developing value in conversing between bounded values (evaluations) and unbounded reality (evaluand), with humility; (ii) developing response-ability with evaluand stakeholders based on reflexivity, with empathy; and (iii) developing adaptive rather than mere contingent use(fulness) of STCS ‘tools’ as part of evaluation praxis, with inevitable fallibility and an orientation towards bricolage (adaptive use). The features hint towards systemic evaluation as core to a reconfigured notion of developmental evaluation

    Fall Prediction and Prevention Systems: Recent Trends, Challenges, and Future Research Directions.

    Get PDF
    Fall prediction is a multifaceted problem that involves complex interactions between physiological, behavioral, and environmental factors. Existing fall detection and prediction systems mainly focus on physiological factors such as gait, vision, and cognition, and do not address the multifactorial nature of falls. In addition, these systems lack efficient user interfaces and feedback for preventing future falls. Recent advances in internet of things (IoT) and mobile technologies offer ample opportunities for integrating contextual information about patient behavior and environment along with physiological health data for predicting falls. This article reviews the state-of-the-art in fall detection and prediction systems. It also describes the challenges, limitations, and future directions in the design and implementation of effective fall prediction and prevention systems

    Ethical guidelines for nudging in information security & privacy

    Get PDF
    There has recently been an upsurge of interest in the deployment of behavioural economics techniques in the information security and privacy domain. In this paper, we consider first the nature of one particular intervention, the nudge, and the way it exercises its influence. We contemplate the ethical ramifications of nudging, in its broadest sense, deriving general principles for ethical nudging from the literature. We extrapolate these principles to the deployment of nudging in information security and privacy. We explain how researchers can use these guidelines to ensure that they satisfy the ethical requirements during nudge trials in information security and privacy. Our guidelines also provide guidance to ethics review boards that are required to evaluate nudge-related research

    Privacy in crowdsourcing:a systematic review

    Get PDF
    The advent of crowdsourcing has brought with it multiple privacy challenges. For example, essential monitoring activities, while necessary and unavoidable, also potentially compromise contributor privacy. We conducted an extensive literature review of the research related to the privacy aspects of crowdsourcing. Our investigation revealed interesting gender differences and also differences in terms of individual perceptions. We conclude by suggesting a number of future research directions.</p
