Project
FogBlock4Trust aims at realizing a Fog-assisted Blockchain-based credential management solution to strengthen the trust and privacy of users. It aims to integrate Fog Computing and blockchain technologies in order to deliver specific credential validation services. The envisioned fog-enhanced blockchain-based system will provide both trusted global accreditation and distributed credential verification within one framework. As many credential verification systems were recently developed, e.g. due to the need of a reliable COVID-19 vaccination passport management, most of these systems use centralized approaches, while only few deployed the innovative blockchain technology. Our FogBlock4Trust project also fully complies with European GDPR regulations, and allows for decreased latency and enhanced efficiency, along with higher security within the system.

Cloud Computing offers on-demand access to computational, infrastructure and data resources operated from a remote source. In the current worldwide ICT scenario a constantly growing number of powerful devices join the Internet, significantly impacting on the global traffic volume and foreshadowing a world of smart devices, or things in the Internet of Things perspective, interconnected by the Internet. By addressing the challenges of this vision, the overall goal of this project is to support the proliferation of IoT with the help of fog and cloud technologies. The aim of this OTKA FK 131793 project is to model the behavior of IoT devices and sensors, and to apply this model in simulated environments to enable the analysis of efficient and secure management strategies of IoT applications by performing fundamental research in the area of Fog and Cloud computing and the Internet of Things. This research plans to contribute to the better planning and estimation of IoT application costs by using our proposed solutions.

In developed countries, we spend 80-90% of our time indoors, where we receive most of our exposure to air pollution. However, regulation for air pollution focuses mainly on outdoors and the indoor environment is much less well characterised. The concentrations of many air pollutants can be higher indoors than out, particularly following activities such as cleaning and cooking. With increasing climate change impacts, related energy efficiency measures are making buildings considerably more airtight. Such measures can increase indoor pollutant concentrations even further. Therefore, to reduce our exposure to air pollution, we must consider both the indoor and outdoor environments and the role of ventilation, in order to mitigate through appropriate building operation, use and design. INDAIRPOLLNET (INDoor AIR POLLution NETwork) will improve our understanding of the cause of high concentrations of indoor air pollutants. It will assemble experts in laboratory and chamber experiments, modelling studies and measurements of relevance to indoor air quality (IAQ), including outdoor air chemists. Our network includes experts in chemistry, biology, standardisation, particulate matter characterisation, toxicology, exposure assessment, building materials (including those manufactured specifically to improve IAQ such as green materials), building physics and engineering (including ventilation and energy) and building design. This project aims to significantly advance the field of indoor air pollution science, to highlight future research areas and to bridge the gap between research and business to identify appropriate mitigation strategies that optimise IAQ. The findings will be disseminated to relevant stakeholders such as architects, building engineers and instrument manufacturers.
