    HomePad: A Privacy-aware Smart Hub for Home Environments

    No full text
    The adoption of smart home devices is hindered today by the privacy concerns users have regarding their personal data. Since these devices depend on remote service providers, users remain oblivious about how and when their data is disclosed and processed. In this paper we present HomePad, a privacy-aware smart hub for home environments. Our system aims to empower users with the ability to determine how applications can access and process sensitive data collected by smart devices (e.g., web cams) and to prevent applications from executing unless they abide by the privacy restrictions specified by the users. To achieve this goal, HomePad applications are implemented as directed graphs of elements, which consist of instances of functions that process data in isolation. By modeling elements and the flow graph using Prolog rules, HomePad allows for automatic verification of the application’s flow graph against user-defined privacy policies. Homepad incurs a negligible performance overhead, requires a modest programming effort, and provides flexible policy support to address the privacy concerns most commonly expressed by potential smart device consumers

    peer-reviewedThe main threats to soils outlined in the pending Soil Framework Directive (SFD) are: contamination, loss of organic matter, erosion, compaction, sealing, salinization and desertification. The first four threats are pertinent to agricultural systems in Atlantic Europe, but vary in their extent between countries depending on the spatial soil distribution. Loss of soil biodiversity has not been included as a potential threat in the SFD due to lack of information that is currently available both spatially and temporally to facilitate any legislation to protect it. This paper gives emphasis to the four main threats outlined above associated with Agricultural systems in Atlantic Europe. Each soil threat is discussed in relation to the agricultural management calendar for cultivated and grazed grassland soils. The paper discusses current soil protection policies and possible changes to such legislation with the adoption of the SFD by member states
