Healthcare Monitoring

Healthcare professionals and scholars have emphasized the need for IoT-based remote health monitoring services to track the health of the elderly. Such systems produce a large amount of data, necessitating the security and privacy of that data. On the other hand, Software Defined Networking (SDN) integration could be seen as a good solution to guarantee both flexibility and efficiency of the network which is even more important in the case of healthcare monitoring. Furthermore, Blockchain has recently been proposed as a game-changing tool that can be integrated into the Internet of Things (IoT) to have the optimal level of security and privacy. However, incorporating Blockchain into IoT networks, which rely heavily on patients’ health sensors, is extremely difficult. In this paper, a secure Healthcare Monitoring System (HMS) is proposed with a focus on trust management issues. The architecture seeks to protect multiple healthcare monitoring system components and preserves patient privacy by developing a security interface where separate security modules can be integrated to run side by side to ensure reliable HMS. The security framework architecture we propose takes advantage of the blockchain technology as a secure and timely information back-end. STHM is a proposal that uses Software-Defined Networking (SDN) as the communication medium that allows users to access SDN’s different functional and security technologies and services. Simulation results show that the use of Blockchain for the SDN-based healthcare monitoring can ensure the desired flexibility and security for a very lightweight additional overhead.

And Performance

Blockchain provides innovative ideas for storing information, executing transactions, performing functions, creating trust in an open environment, etc. Even though cryptographers, mathematicians, and coders have been trying to bring the most trustable protocols to get authentication guarantee over various systems, blockchain technology is secure with no central authority in an open network system because of a large distributed network of independent users. If anyone tries to change the blockchain database, the current hash will also change, which does not match with the previous hash. In this way, blockchain creates privacy and trust in digital data by removing malleability attacks. In this chapter, security and privacy on the blockchain has been focused. The safety and privacy of blockchain are mainly engrossed on two things: firstly, uncovering few attacks suffered by blockchain systems and, secondly, putting specific and advanced proposals against such attacks.

Blockchain-based electronic health system growth is hindered by privacy, confidentiality, and security. By protecting against them, this research aims to develop cybersecurity measurement approaches to ensure the security and privacy of patient information using blockchain technology in healthcare. Blockchains need huge resources to store big data. This paper presents an innovative solution, namely patient-centric healthcare data management (PCHDM). It comprises the following: (i) in an on-chain health record database, hashes of health records are stored as health record chains in Hyperledger fabric, and (ii) off-chain solutions that encrypt actual health data and store it securely over the interplanetary file system (IPFS) which is the decentralized cloud storage system that ensures scalability, confidentiality, and resolves the problem of blockchain data storage. A security smart contract hosted through container technology with Byzantine Fault Tolerance consensus ensures patient privacy by verifying patient preferences before sharing health records. The Distributed Ledger technology performance is tested under hyper ledger caliper benchmarks in terms of transaction latency, resource utilization, and transaction per second. The model provides stakeholders with increased confidence in collaborating and sharing their health records.

The Internet of Things (IoT) is one of the most promising scientific fields of the last decade. The number of devices developed that support Internet things makes the application of internet things more interesting. The field of use includes the insurance sector, intelligent monitoring Environment, Smart City, sector-health care, Intelligent City, and also many other applications enabled for smart devices.The vision of the introduction of the internet, forming a network called IoT, where various information technology devices are connected, security and trust are most important for the user, because this network presumably used a large amount of data.However, trust is a significant obstacle that can hinder the growth of the IoT and even slow down the significant compression of many applications.This paper presents an approach using trust management (TM) with next-generation IoT networks for healthcare, agriculture, and sustainable development goals. Implementation of IoT conveys various problems of security and confidentiality. The use of IoT to ensure confidentiality, integrity, authentication, authorization, trust, secrecy, and management challenges are addressed. The paper uses decentralized blockchain technology to solve security and privacy issues in applications with the support of the IoT.Ethereum virtual machine is used to implement theBlockchain distributed networkand healthcare insurance claims are taken as anexample to test the proposed solution. Also, it is provided that the lessons and opinions discussed are primarily about the purpose of the trust, which can be reproduced in the future on the internet.The results show that distributed blockchain technology provides trust management and can improve the existing security and privacy of the IoT in the health and agriculture sectors, which is helpful for next-generation IoT networks.

BACKGROUND Time banking is a good mechanism to provide elderly care in community services with members having mutual benefits, besides social welfare and out-of-pocket fee payment mechanisms. With further integration with off-line works, mobile time banking may provide a better way, compared to traditional web access. On the other hand, blockchain technology has been long encountering difficulty in integrating with real-world economies or activities. Development of a mobile time banking system on blockchain (MTBB) may provide a realistic solution for community elderly care. Besides, the tracking mechanism from blockchain technology itself may also help track the elderly care service transaction records in order to measure better Sustainable Development Goals (SDGs) set by United Nations (UN). OBJECTIVE The aim of this study was to develop the MTBB, which enables tracking service transaction records in community elderly care through mutual helps. METHODS The MTBB was developed to empower organizations, either Corporate Social Responsibility (CSR) organizations, or Non-Profit Organizations (NPOs), to issue time tokens of their proprietary token types to the members who participate in the volunteer activities organized by the organizations respectively. In the service activities, members sign in and sign out before and after the services by using a smartphone app, and then get the time tokens afterwards. Members with time tokens can then exchange time tokens for elderly care services using the same smartphone app. MultiChain is used as the blockchain technology stack, as one of its features to support multiple token types is critical. RESULTS Database applications with smartphone apps integrated with MultiChain were developed. The whole set of the database schema was integrated with two smartphone apps, one for members, and the other for organizations, in addition to the two backend operations modules, one for organizations, and the other for managing all organizations and members. The MultiChain wallet was also integrated into the member app, as well as the organization backend modules for keeping track of the service transactions and time tokens. Metadata with the service transaction information is stored in the MultiChain blocks so that the transaction records are immutable and can thus be analyzed in the future. CONCLUSIONS The twelve characteristics of Cahn’s time banking are the guidelines of developing this MTBB with integration of MultiChain blockchain technology for tracking service transaction records. The study also combines the 1-to-1 member service exchange with organizations holding volunteer activities and issuing proprietary time tokens. With the blockchain transaction tracking mechanism, all of the elderly care service records through or within organizations can be tracked and analyzed to align with UN’s five SDGs.

Accurate monitoring of motion and sleep states is critical for human health assessment, especially for a healthy life, early diagnosis of diseases, and medical care. In this work, a smart wearable sensor (SWS) based on a dual-channel triboelectric nanogenerator was presented for a real-time health monitoring system. The SWS can be worn on wrists, ankles, shoes, or other parts of the body and cloth, converting mechanical triggers into electrical output. By analyzing these signals, the SWS can precisely and constantly monitor and distinguish various motion states, including stepping, walking, running, and jumping. Based on the SWS, a fall-down alarm system and a sleep quality assessment system were constructed to provide personal healthcare monitoring and alert family members or doctors via communication devices. It is important for the healthy growth of the young and special patient groups, as well as for the health monitoring and medical care of the elderly and recovered patients. This work aimed to broaden the paths for remote biological movement status analysis and provide diversified perspectives for true-time and long-term health monitoring, simultaneously.
