Why blockchain should assist smart cities in preserving privacy

Recent advances in cloud and edge computing, network and big data processing will have an impact on smart cities that could make a significant shift in data privacy and sovereignty.

The rapid development of Smart Cities is facilitated by the convergence of information and communication technologies (ICT). Data is a key element of Smart City applications as well as a serious concern. Data is the critical factor that drives the entire development lifecycle in most smart city use cases, according to a comprehensive review of several smart city use cases.

Poor data management, on the other hand, can have serious repercussions for programs that obtain incorrect data and for users whose privacy may be compromised. Therefore, we believe that an integrated ICT solution in smart cities is essential to achieve the highest levels of scalability, data integrity and privacy within and between smart cities.

There are a variety of modern technologies for smart cities that offer integrated architectures, which connect Blockchain technologies with modern data analytics techniques (e.g., Federated Learning) and Edge/Fog computing to solve today’s problems. data privacy in smart cities.

Turn

Recent advances in cloud and edge computing, networking, and big data processing are driving growing interest in IoT and Smart City applications. If properly implemented, smart cities could make a significant shift in privacy and data sovereignty by processing data locally, avoiding the concentration of private and sensitive data in the hands of a few cloud providers.

Many of the urban areas are already filled with computing resources and connected devices such as IP cameras, traffic lights and all kinds of sensors. The Cloud Continuum, however, is very fragmented. IoT networks, cloud computing, and network providers are all deployed and operated in silos that prevent their discovery and complicate their integration into real-world applications. These silos also tend to create friction for new players wishing to enter a market and threaten the privacy of end users as far as ambitious application scenarios such as e-health, e-governance, services public, mobility and transport will require the sharing of more and more data between the different parties, transparency.

Benefiting from recent advances in distributed systems, networks and IoT, smart cities are expected to improve the quality of life of city dwellers and propel cities towards a more sustainable future. The availability of a variety of IoT actively contributes to the development of smart cities, but the huge amount of data that must be generated, stored, classified, analyzed and transferred to provide context-aware real-time services to inhabitants creates challenges.

Ecosystem

The scalable management of ICT infrastructure, the successful monetization of data, applications and computing resources, and the development of privacy-enhancing hybrid technologies are three essential criteria for developing advanced privacy-preserving Smart City ecosystems. In particular, performing data processing in remote cloud data centers has many limitations in terms of performance, resiliency, power efficiency, and privacy.

Renowned computer scientist, Professor John McCarthy, envisioned a futuristic computing environment where processing power, applications and data could be structured as a public service and sold through a measured business model at the dawn of the contemporary computing age. . According to Professor John McCarthy, such an ecosystem could enable scalable access to virtually unlimited computing resources as well as a wide range of computing services. Selling processing power, applications and data has finally become a reality and a market largely dominated by a few large IT companies. Therefore, individuals and small and medium-sized enterprises face huge obstacles in entering this market. More recently, several independent marketplaces have emerged, considering that open, regulated, uniformly governed and federated marketplaces are necessary to break out of the current oligopoly.

Nevertheless, a significant problem that remains for any market is to provide verified, reliable and relevant resources to gain the trust of buyers. Because they can provide security, transparency, auditability and traceability of all peer-to-peer transactions and transactions, blockchain technologies are seen as a major enabler in meeting the needs of decentralized marketplaces.

Sustainable Smart City

One of the essential conditions for developing a sustainable Smart City is adaptability, for which artificial intelligence (AI) and machine learning (ML) technologies can play an important role. In the context of smart cities and AI, data is one of the most critical components. However, the data raises two important concerns; first, managing data without infringing the privacy of its owners can be difficult, as it constantly flows from one computer system to another; second, the security and performance of AI/ML applications can be compromised by fabricated or corrupted data.

Maintaining a high level of security throughout the IT chain is paramount to protecting data, and can only be achieved through comprehensive infrastructure management and auditability. Using the three main frames ICT benchmark: DC2C-ICT (Decentralized-to-Centralized), D2C-ICT (Distributed-to-Centralized), and Hybrid shows how storage, management, processing, data analytics, and software service management can be carried out efficiently within and between cities as part of the Smart City.

blockchain

A blockchain-based marketplace helps build a decentralized marketplace for software devices (e.g. apps, VMs, containers), computing resources (cloud, cloud, and edge), and data generators (e.g., sensors, actuators, transportation services, health monitoring sensors). This component allows individuals and small/medium/large enterprises to have equal opportunities to monetize their resources (eg IT, data and applications); thus, it extends the global infrastructure and makes it highly diverse.

Blockchain technology makes the market fully traceable and transparent for all its participants; each task execution and corresponding transaction are permanently recorded on the Blockchain nodes. Market mechanisms take into account the reputation of resource providers and their resources: the reputation of resource providers is built on the basis of their past operations and the quality of the services they have offered in the past. The Blockchain-based market ensures open and fair competition between different resource providers,

One of the main goals of this blockchain-based marketplace is to bring more trust between different participants.
