Towards Blockchain-based Remote Management Systems for Patients with Movement Disorders
Secure storage and sharing of patients' medical data over the Internet are
part of the challenges for emerging healthcare systems. The use of blockchain
technology in medical Internet of things systems can be considered a safe and
novel solution to overcome such challenges. Patients with movement disorders
require multi-disciplinary management and must continuously receive medical
care from a specialist. Due to the increasing costs of face-to-face treatment,
especially during the pandemic, patients would highly benefit from remote
monitoring and management. The proposed work presents a model for
blockchain-based remote management systems for patients with movement
disorders, especially those with Parkinson's disease. The model ensures a high
level of integrity and decreases the security risks of medical data sharing.Comment: Presented at the 31th International Conference on Electrical

Blockchain for IoT Access Control: Recent Trends and Future Research Directions
With the rapid development of wireless sensor networks, smart devices, and
traditional information and communication technologies, there is tremendous
growth in the use of Internet of Things (IoT) applications and services in our
everyday life. IoT systems deal with high volumes of data. This data can be
particularly sensitive, as it may include health, financial, location, and
other highly personal information. Fine-grained security management in IoT
demands effective access control. Several proposals discuss access control for
the IoT, however, a limited focus is given to the emerging blockchain-based
solutions for IoT access control. In this paper, we review the recent trends
and critical needs for blockchain-based solutions for IoT access control. We
identify several important aspects of blockchain, including decentralised
control, secure storage and sharing information in a trustless manner, for IoT
access control including their benefits and limitations. Finally, we note some
future research directions on how to converge blockchain in IoT access control
efficiently and effectively
From Generative AI to Generative Internet of Things: Fundamentals, Framework, and Outlooks
Generative Artificial Intelligence (GAI) possesses the capabilities of
generating realistic data and facilitating advanced decision-making. By
integrating GAI into modern Internet of Things (IoT), Generative Internet of
Things (GIoT) is emerging and holds immense potential to revolutionize various
aspects of society, enabling more efficient and intelligent IoT applications,
such as smart surveillance and voice assistants. In this article, we present
the concept of GIoT and conduct an exploration of its potential prospects.
Specifically, we first overview four GAI techniques and investigate promising
GIoT applications. Then, we elaborate on the main challenges in enabling GIoT
and propose a general GAI-based secure incentive mechanism framework to address
them, in which we adopt Generative Diffusion Models (GDMs) for incentive
mechanism designs and apply blockchain technologies for secure GIoT management.
Moreover, we conduct a case study on modern Internet of Vehicle traffic
monitoring, which utilizes GDMs to generate effective contracts for
incentivizing users to contribute sensing data with high quality. Finally, we
suggest several open directions worth investigating for the future popularity
of GIoT

ENABLING IOT AUTHENTICATION, PRIVACY AND SECURITY VIA BLOCKCHAIN
Although low-power and Internet-connected gadgets and sensors are increasingly integrated into our lives, the optimal design of these systems remains an issue. In particular, authentication, privacy, security, and performance are critical success factors. Furthermore, with emerging research areas such as autonomous cars, advanced manufacturing, smart cities, and building, usage of the Internet of Things (IoT) devices is expected to skyrocket. A single compromised node can be turned into a malicious one that brings down whole systems or causes disasters in safety-critical applications. This dissertation addresses the critical problems of (i) device management, (ii) data management, and (iii) service management in IoT systems. In particular, we propose an integrated platform solution for IoT device authentication, data privacy, and service security via blockchain-based smart contracts. We ensure IoT device authentication by blockchain-based IC traceability system, from its fabrication to its end-of-life, allowing both the supplier and a potential customer to verify an IC’s provenance. Results show that our proposed consortium blockchain framework implementation in Hyperledger Fabric for IC traceability achieves a throughput of 35 transactions per second (tps). To corroborate the blockchain information, we authenticate the IC securely and uniquely with an embedded Physically Unclonable Function (PUF). For reliable Weak PUF-based authentication, our proposed accelerated aging technique reduces the cumulative burn-in cost by ∼ 56%. We also propose a blockchain-based solution to integrate the privacy of data generated from the IoT devices by giving users control of their privacy. The smart contract controlled trust-base ensures that the users have private access to their IoT devices and data. We then propose a remote configuration of IC features via smart contracts, where an IC can be programmed repeatedly and securely. This programmability will enable users to upgrade IC features or rent upgraded IC features for a fixed period after users have purchased the IC. We tailor the hardware to meet the blockchain performance. Our on-die hardware module design enforces the hardware configuration’s secure execution and uses only 2,844 slices in the Xilinx Zedboard Zynq Evaluation board. The blockchain framework facilitates decentralized IoT, where interacting devices are empowered to execute digital contracts autonomously
Blockchain technology and green supply chain management (GSCM) - improving environmental and energy performance in multi-echelon supply chains
In this competitive and technology driven world, businesses are striving to gain benefits of environmental sustainability and energy conservation by implementing the latest technologies in their supply chains. A promising way of evaluating the environmental performance of a product or a process is Life Cycle Assessment (LCA) modelling, but the reliability of LCA results is mostly compromised due to the lack of real data from upstream and downstream supply chains. Our research aim is to drive LCA modelling through Blockchain Technology (BCT) and internet-of-things which have the capability to record reliable, transparent, and secure data from across the supply chain. The modified LCA model will provide various industries with the quantified benefits of BCT in terms of industrial emissions reduction. This conference paper reflects the 1st stage of research where we carried out a detailed literature review on potential use of blockchain technology in green supply chain management and based on the findings, we developed an integrative framework architecture for the supply chain of a supermarket product. In the next phase, the integration of BCT and LCA will be studied in food supply chains using a supermarket case study of Walmart-IBM developed blockchain consortium
On the Convergence of Blockchain and Internet of Things (IoT) Technologies
The Internet of Things (IoT) technology will soon become an integral part of
our daily lives to facilitate the control and monitoring of processes and
objects and revolutionize the ways that human interacts with the physical
world. For all features of IoT to become fully functional in practice, there
are several obstacles on the way to be surmounted and critical challenges to be
addressed. These include, but are not limited to cybersecurity, data privacy,
energy consumption, and scalability. The Blockchain decentralized nature and
its multi-faceted procedures offer a useful mechanism to tackle several of
these IoT challenges. However, applying the Blockchain protocols to IoT without
considering their tremendous computational loads, delays, and bandwidth
overhead can let to a new set of problems. This review evaluates some of the
main challenges we face in the integration of Blockchain and IoT technologies
and provides insights and high-level solutions that can potentially handle the
shortcomings and constraints of both IoT and Blockchain technologies.Comment: Includes 11 Pages, 3 Figures, To publish in Journal of Strategic
