A flexible architecture for privacy-aware trust management

In service-oriented systems a constellation of services cooperate, sharing potentially sensitive information and responsibilities. Cooperation is only possible if the different participants trust each other. As trust may depend on many different factors, in a flexible framework for Trust Management (TM) trust must be computed by combining different types of information. In this paper we describe the TAS3 TM framework which integrates independent TM systems into a single trust decision point. The TM framework supports intricate combinations whilst still remaining easily extensible. It also provides a unified trust evaluation interface to the (authorization framework of the) services. We demonstrate the flexibility of the approach by integrating three distinct TM paradigms: reputation-based TM, credential-based TM, and Key Performance Indicator TM. Finally, we discuss privacy concerns in TM systems and the directions to be taken for the definition of a privacy-friendly TM architecture.\u

Cloud service localisation

The essence of cloud computing is the provision of software and hardware services to a range of users in dierent locations. The aim of cloud service localisation is to facilitate the internationalisation and localisation of cloud services by allowing their adaption to dierent locales. We address the lingual localisation by providing service-level language translation techniques to adopt services to dierent languages and regulatory localisation by providing standards-based mappings to achieve regulatory compliance with regionally varying laws, standards and regulations. The aim is to support and enforce the explicit modelling of aspects particularly relevant to localisation and runtime support consisting of tools and middleware services to automating the deployment based on models of locales, driven by the two localisation dimensions. We focus here on an ontology-based conceptual information model that integrates locale specication in a coherent way

No Grice: Computers that Lie, Deceive and Conceal

In the future our daily life interactions with other people, with computers, robots and smart environments will be recorded and interpreted by computers or embedded intelligence in environments, furniture, robots, displays, and wearables. These sensors record our activities, our behavior, and our interactions. Fusion of such information and reasoning about such information makes it possible, using computational models of human behavior and activities, to provide context- and person-aware interpretations of human behavior and activities, including determination of attitudes, moods, and emotions. Sensors include cameras, microphones, eye trackers, position and proximity sensors, tactile or smell sensors, et cetera. Sensors can be embedded in an environment, but they can also move around, for example, if they are part of a mobile social robot or if they are part of devices we carry around or are embedded in our clothes or body. \ud \ud Our daily life behavior and daily life interactions are recorded and interpreted. How can we use such environments and how can such environments use us? Do we always want to cooperate with these environments; do these environments always want to cooperate with us? In this paper we argue that there are many reasons that users or rather human partners of these environments do want to keep information about their intentions and their emotions hidden from these smart environments. On the other hand, their artificial interaction partner may have similar reasons to not give away all information they have or to treat their human partner as an opponent rather than someone that has to be supported by smart technology.\ud \ud This will be elaborated in this paper. We will survey examples of human-computer interactions where there is not necessarily a goal to be explicit about intentions and feelings. In subsequent sections we will look at (1) the computer as a conversational partner, (2) the computer as a butler or diary companion, (3) the computer as a teacher or a trainer, acting in a virtual training environment (a serious game), (4) sports applications (that are not necessarily different from serious game or education environments), and games and entertainment applications

Privacy, security, and trust issues in smart environments

Recent advances in networking, handheld computing and sensor technologies have driven forward research towards the realisation of Mark Weiser's dream of calm and ubiquitous computing (variously called pervasive computing, ambient computing, active spaces, the disappearing computer or context-aware computing). In turn, this has led to the emergence of smart environments as one significant facet of research in this domain. A smart environment, or space, is a region of the real world that is extensively equipped with sensors, actuators and computing components [1]. In effect the smart space becomes a part of a larger information system: with all actions within the space potentially affecting the underlying computer applications, which may themselves affect the space through the actuators. Such smart environments have tremendous potential within many application areas to improve the utility of a space. Consider the potential offered by a smart environment that prolongs the time an elderly or infirm person can live an independent life or the potential offered by a smart environment that supports vicarious learning

Teaching "Concertation" : the Acceptance of Conflicts and the Experience of Creativity Using La Francilienne Cd Rom

In this paper , I will describe and discuss my use of La Francilienne Cd Rom I developed with my colleague Alain Lempereur, Law Professor at ESSEC Business School, Paris. As a Professor in the ESSEC Department of Environment, I use the Cd Rom as the basic tool for my course "Concertation , Decision and Local Democracy". The Cd Rom's simulation of a concertation process on a highway project allows me not only to teach basic concepts and methods of negotiation and mediation, as we will see, but also to enhance two important concepts in public decision processes in planning and environment: conflicts and creativity. The students are given the opportunity to experience then to discuss conflicts and creativity in a quasi-real setting. These experiences and discussions, which come close to an internal change for the students, help them to integrate the negotiation and mediation concepts and methods taught. This internal change will be conceptualized using transitional thinking theory and experiential learning theory. A narrative will show the students' internal change occurrence along the course. We will see that La Francilienne Cd Rom offers a relevant context and tool for it.After a presentation of the course, I will continue with a detailed narrative of how I use the Cd Rom and will finish with a discussion on several important choices made in my pedagogical approach.Multimedia teaching; Teaching Concertation; Negotiation and Mediation; Conflicts; Creativity; Planning and Environment

Enhancing the Effectiveness of Social Dialogue Articulation in Europe (EESDA) Project No. VS/2017/0434 Social Dialogue Articulation and Effectiveness: Country Report for France

This report presents a country study analysing the articulation and effectiveness of social dialogue in France. The methodological approach relies on desk research and semi-structured interviews with social partners in France, aiming at obtaining deeper insights into how issues are articulated in French social dialogue, actors are interacting, and how social dialogue outcomes are achieved – and ultimately implemented. Following a brief historical background on the industrial relations system and the evolutions in the French context after a series of reforms, the report then provides both a cross-sectoral overview of social dialogue articulation and the interaction with European-level social dialogue. It also offers a sectoral perspective by looking at four sectors with a particular focus on four occupations within these sectors: commerce (sales agents), construction (construction workers), education (teachers) and healthcare (nurses). The research suggests a diversity of experiences both in cross-sectoral and sectoral social dialogue articulation and their effectiveness depending on the type of actor (e.g. trade unions, employer organisations, etc.) and on the sector of focus. The perceptions of social dialogue effectiveness are mixed in the face of continuous reforms over the last decades. Interactions with European-level social dialogue and social partners is considered as important (particularly in some sectors), but the intensity of the interaction is limited when it comes to involvement in the European Semester process

Personal recommendations in requirements engineering : the OpenReq approach

[Context & motivation] Requirements Engineering (RE) is considered as one of the most critical phases in software development but still many challenges remain open. [Problem] There is a growing trend of applying recommender systems to solve open RE challenges like requirements and stakeholder discovery; however, the existent proposals focus on specific RE tasks and do not give a general coverage for the RE process. [Principal ideas/results] In this research preview, we present the OpenReq approach to the development of intelligent recommendation and decision technologies that support different phases of RE in software projects. Specifically, we present the OpenReq part for personal recommendations for stakeholders. [Contribution] OpenReq aim is to improve and speed up RE processes, especially in large and distributed systemsPeer ReviewedPostprint (author's final draft
