    WSN Location Privacy Scheme Enhancement through Epidemical Information Dissemination

    Get PDF
    Wireless Sensor Networks (WSNs) are commonly used for animal tracking. Over the years, a significant number of studies have been presented for monitoring moving targets through WSN. At the same time, the location / position information of each target should be available only to authorized entities, e.g., Animal Protection Centers, thus, the position should be kept private. The iHIDE is a location privacy mechanism that uses a non-geographical based routing scheme for packet delivery over WSN. In this paper, we elaborate on that scheme by introducing a routing plan construction algorithm. Furthermore, we enhance iHIDE by adopting the use of epidemical data dissemination as an enforcing privacy technique. Finally, we evaluate through simulations the scheme against other commonly used location privacy overlays in terms of network overhead and safety period

    High-Performance Modelling and Simulation for Big Data Applications

    This open access book was prepared as a Final Publication of the COST Action IC1406 “High-Performance Modelling and Simulation for Big Data Applications (cHiPSet)“ project. Long considered important pillars of the scientific method, Modelling and Simulation have evolved from traditional discrete numerical methods to complex data-intensive continuous analytical optimisations. Resolution, scale, and accuracy have become essential to predict and analyse natural and complex systems in science and engineering. When their level of abstraction raises to have a better discernment of the domain at hand, their representation gets increasingly demanding for computational and data resources. On the other hand, High Performance Computing typically entails the effective use of parallel and distributed processing units coupled with efficient storage, communication and visualisation systems to underpin complex data-intensive applications in distinct scientific and technical domains. It is then arguably required to have a seamless interaction of High Performance Computing with Modelling and Simulation in order to store, compute, analyse, and visualise large data sets in science and engineering. Funded by the European Commission, cHiPSet has provided a dynamic trans-European forum for their members and distinguished guests to openly discuss novel perspectives and topics of interests for these two communities. This cHiPSet compendium presents a set of selected case studies related to healthcare, biological data, computational advertising, multimedia, finance, bioinformatics, and telecommunications

    “Be a Pattern for the World”: The Development of a Dark Patterns Detection Tool to Prevent Online User Loss

    Get PDF
    Dark Patterns are designed to trick users into sharing more information or spending more money than they had intended to do, by configuring online interactions to confuse or add pressure to the users. They are highly varied in their form, and are therefore difficult to classify and detect. Therefore, this research is designed to develop a framework for the automated detection of potential instances of web-based dark patterns, and from there to develop a software tool that will provide a highly useful defensive tool that helps detect and highlight these patterns

    Technical Debt is an Ethical Issue

    Get PDF
    We introduce the problem of technical debt, with particular focus on critical infrastructure, and put forward our view that this is a digital ethics issue. We propose that the software engineering process must adapt its current notion of technical debt – focusing on technical costs – to include the potential cost to society if the technical debt is not addressed, and the cost of analysing, modelling and understanding this ethical debt. Finally, we provide an overview of the development of educational material – based on a collection of technical debt case studies - in order to teach about technical debt and its ethical implication

    Minding the Gap: Computing Ethics and the Political Economy of Big Tech

    Get PDF
    In 1988 Michael Mahoney wrote that “[w]hat is truly revolutionary about the computer will become clear only when computing acquires a proper history, one that ties it to other technologies and thus uncovers the precedents that make its innovations significant” (Mahoney, 1988). Today, over thirty years after this quote was written, we are living right in the middle of the information age and computing technology is constantly transforming modern living in revolutionary ways and in such a high degree that is giving rise to many ethical considerations, dilemmas, and social disruption. To explore the myriad of issues associated with the ethical challenges of computers using the lens of political economy it is important to explore the history and development of computer technology

    Proceedings of the ETHICOMP 2022: Effectiveness of ICT ethics - How do we help solve ethical problems in the field of ICT?

    Get PDF
    This Ethicomp is again organized in exceptional times. Two previous ones were forced to turn to online conferences because of Covid-pandemic but it was decided that this one would be the physical one or cancelled as the need for real encounters and discussion between people are essential part of doing philosophy. We need possibility to meet people face to face and even part of the presentation were held distance–because of insurmountable problems of arriving by some authors– we manage to have real, physical conference, even the number of participants was smaller than previous conferences.The need of Ethicomp is underlined by the way world nowadays is portrayed for us. The truthfulness and argumentation seem to be replaced by lies, strategic games, hate and disrespect of humanity in personal, societal and even global communication. EThicomp is many times referred as community and therefore it is important that we as community do protect what Ethicomp stands for. We need to seek for goodness and be able to give argumentation what that goodness is. This lead us towards Habermass communicative action and Discourse ethics which encourages open and respectful discourse between people (see eg.Habermass 1984;1987;1996). However, this does not mean that we need to accept everything and everybody. We need to defend truthfulness, equality and demand those from others too. There are situations when some people should be removed from discussions if they neglect the demand for discourse. Because by giving voice for claims that have no respect for argumentation, lacks the respect of human dignity or are not ready for mutual understanding (or at least aiming to see possibility for it) we cannot have meaningful communication. This is visible in communication of all levels today and it should not be accepted, but resisted. It is duty of us all.</p
