Snap4City Platform to Speed Up Policies

AbstractIn the development of smart cities, there is a great emphasis on setting up so-called Smart City Control Rooms, SCCR. This paper presents Snap4City as a big data smart city platform to support the city decision makers by means of SCCR dashboards and tools reporting in real time the status of several of a city's aspects. The solution has been adopted in European cities such as Antwerp, Florence, Lonato del Garda, Pisa, Santiago, etc., and it is capable of covering extended geographical areas around the cities themselves: Belgium, Finland, Tuscany, Sardinia, etc. In this paper, a major use case is analyzed describing the workflow followed, the methodologies adopted and the SCCR as the starting point to reproduce the same results in other smart cities, industries, research centers, etc. A Living Lab working modality is promoted and organized to enhance the collaboration among municipalities and public administration, stakeholders, research centers and the citizens themselves. The Snap4City platform has been realized respecting the European Data Protection Regulation (GDPR), and it is capable of processing every day a multitude of periodic and real-time data coming from different providers and data sources. It is therefore able to semantically aggregate the data, in compliance with the Km4City multi-ontology and manage data: (i) having different access policies; and (ii) coming from traditional sources such as Open Data Portals, Web services, APIs and IoT/IoE networks. The aggregated data are the starting point for the services offered not only to the citizens but also to the public administrations and public-security service managers, enabling them to view a set of city dashboards ad hoc composed on their needs, for example, enabling them to modify and monitor public transportation strategies, offering the public services actually needed by citizens and tourists, monitor the air quality and traffic status to establish, if impose or not, traffic restrictions, etc. All the data and the new knowledge produced by the data analytics of the Snap4City platform can also be accessed, observing the permissions on each kind of data, thanks to the presence of an APIs complex system

Fast Multi-party Private Set Operations in the Star Topology from Secure ANDs and ORs

Today, our society produces massive amounts of data, part of which are strictly private. So, a long line of research has worked to design protocols that perform functions on such private data without revealing them. One function that has attracted significant interest is a multi-party private set operation, where each party\u27s input is a set. The parties commonly intend to compute these sets\u27 collective intersection (MPSI) or union (MPSU), which finds uses in various applications, including private scheduling and threat intelligence. Most current protocols use integer-based homomorphic encryption, with large elements and expensive operations, or oblivious transfers, which require communicationally-expensive pairwise interactions between all parties. Thus, existing solutions introduce significant overhead that hinders practical use. This paper considers a certain class of previously-proposed MPSI and MPSU protocols. We propose to express them in terms of new private AND or OR operations among all parties and use elliptic curves to realize these operations efficiently. We achieve a significant performance gain: Firstly, our protocols take only three rounds of communication. Secondly, our constant-time open-source implementation is two orders of magnitude faster than the state-of-the-art MPSI for small universes and outperforms the state-of-the-art MPSI for large universes for three parties or more

Smart and Sustainable Planning for Cities and Regions

This open access book offers a selection of research papers and case studies presented at the 3rd international conference “Smart and Sustainable Planning for Cities and Regions”, held in December 2019 in Bolzano, Italy, and explores the concept of smart and sustainable planning, including top contributions from academics, policy makers, consultants and other professionals. Innovation processes such as co-design and co-creation help establish collaborations that engage with stakeholders in a trustworthy and transparent environment while answering the need for new value propositions. The importance of an integrated, holistic approach is widely recognized to break down silos in local government, in particular, when aimed at achieving a better integration of climate-energy planning. Despite the ongoing urbanization and polarization processes, new synergies between urban and rural areas emerge, linking development opportunities to intrinsic cultural, natural and man-made landscape values. The increasing availability of big, real-time urban data and advanced ICT facilitates frequent assessment and continuous monitoring of performances, while allowing fine-tuning as needed. This is valid not only for individual projects but also on a wider scale. In addition, and circling back to the first point, (big) urban data and ICT can be of enormous help in facilitating engagement and co-creation by raising awareness and by providing insight into the local consequences of specific plans. However, this potential is not yet fully exploited in standard processes and procedures, which can therefore lack the agility and flexibility to keep up with the pulse of the city and dynamics of society. The book provides a multi-disciplinary outlook based on experience to orient the reader in the giant galaxy of smart and sustainable planning, support the transposition of research into practice, scale up visionary approaches and design groundbreaking planning policies and tools
