BlockSee: Blockchain for IoT video surveillance in smart cities
2018
The growing demand for safety in urban environments is supported by monitoring using video surveillance. The need to analyze multiple video-flows from different cameras deployed around the city by heterogeneous owners introduces vulnerabilities and privacy issues. Video frames, timestamps, and camera settings can be digitally manipulated by malicious users; the positions of cameras, their orientation and their mechanical settings can be physically manipulated. Digital and physical manipulations may have several effects, including the change of the observed scene and the potential violation of neighbors' privacy. To face these risks, we introduce BlockSee, a blockchain-based video surveillan…
Challenges and Opportunities using MultiChain for Real Estate
2019
The real estate market involves multiple untrusted actors with contrasting objectives. We propose REchain, a blockchain-based platform for real estate, which provides benefits to all actors in terms of transparency, trust, immutability, and traceability. REchain architecture handles real estate data through well-defined workflows that leverage the MultiChain platform. REchain changes the real estate market enabling direct transactions without intermediaries, and providing new mechanisms for negotiating the purchase conditions. This paper refutes the misleading idea of using blockchains for solving generic problems as blockchain platforms have peculiar features that make them suitable for sp…
Blockchain for Smart Cities: Applications for IoT and Video Surveillance Systems
2020
The recent revolution of the Internet of Things introduces new engaging operat- ing scenarios. The IoT paradigm enables the intertwined use of physical and soft- ware components through the interconnection of devices that exchange data with each other without direct human interaction in several fields, especially in industrial and home environments. In the framework of the Italian-Vietnamese cooperation on the topics of smart cities and Blockchain, we present two applications of the blockchain technology, which can be applied, respectively in indoor, for monitoring and controlling smart homes, and in outdoor, for visual monitoring through video surveillance systems. In both cases, we propos…
Immutabilità del giudice versus efficienza del sistema: il dictum delle Sezioni Unite
2020
In the wake of the Constitutional Court, the ruling of the United Section has redrawn guidelines for the renovation of the “trial” in case of a change, during the course of the proceedings, in the composition of the panel of judges. A decision full of shadows, guided by the necessity to make the duration of proceedings “reasonable”, that certainly will influence the future choices of the legislator in this matter.
