Blockchain Based Aadhaar uses Blockchain platform for securing Aadhaar information. The system stores the Aadhaar data in a group of computers interconnected to each other. The Blockchain uses a hashing function to transform the data and produces a hash code. The hash code ensures the identity of user is kept secure. The data is stored in blocks in the nodes. The system also uses Ethereum Smart Contracts to ensure to only the authenticated data is accessed by the third parties. The Blockchain based Aadhaar uses distributed databases (decentralized databases) math and cryptography to record transactions, transactional data is secured and the data is stored in distributed small chunks and spreads across the entire network of computers, and so it is difficult to hack these systems than hacking the centralized or traditional servers.

Abstract As the concept of the visible product lifecycle and product tracking becomes important to consumers, emerging technologies such as Internet of Things (IoT)-based networks and Blockchain platforms are considered promising solutions by Original Equipment Manufacturers (OEMs) to increase their brand reputation, improve their consumers’ experiences, and reduce their operational costs. However, costly implementation, data verification issues, and the risk of uploading inaccurate information on those platforms have limited the adoption rate and capabilities offered by the aforementioned technologies. Companies often face the question of what type of distributed ledger technology and verification protocol is more efficient in terms of operational costs as well as security. The purpose of this study is to develop an optimization framework to make a trade-off between the cost of implementation of the technology and the security level. The framework is developed based on utility theory principles. The main focus is to discuss the cost associated with various aspects of technology implementation. Finally, this general cost framework is shown as a demo for an example of the food supply chain.

The blockchain is currently under the spotlight of trending technologies. It adds security to private applications in several areas of knowledge, and its versatility results in the development of multiple frameworks to meet the requirements of each application. Thus, it is a key challenge to ensure that blockchain frameworks provide security, access control, and high performance to applications. In this paper, we evaluate two frameworks for blockchain development, Parity, and Multichain, which provide configuration and permission flexibility. Our evaluation is a comprehensive comparison between the frameworks, focusing on the analysis of transaction-validation time, transaction-mining time, transaction-seek time and block-seek time. To this end, we deploy peer-to-peer private permissioned networks, in which the frameworks generate the blockchain applications. For each framework, we provide a realistic workload, based on the distribution of probability of interarrival time of transactions on the Bitcoin network. The results show that each framework stands out under specific criteria, and their design decisions imply restrictions on features that are critical for creating secure and efficient blockchain applications.
The Internet of Things is evolving as a complete matured technology to be used in all the Smart applications and it establishes itself in the future generations of internet. As like Internet of Things, Blockchain is the blooming technology in which each node involved in the blockchain contains the distributed ledger which enhances the security and data transparency. Illegal users are not able to perform any fault transaction in the blockchain network due to its ability of performing smart contract and consensus. The Internet of Things can be merged with the blockchain to improve the performance of the application in real time. However, managing the devices connected to the sensors in IoT environment and mining the block chain remains the technical challenge forever. With this background, an attempt is made to survey the core details of blockchain technology and its features. The design architecture by merging IoT and BlockChain for Satellite Monitoring and ended up with some new architectural framework has been proposed in this paper.

In recent decades, video surveillance systems have become an indispensable management tool for cities. Managers can grasp the information of the scene without visiting the scene. Through the surveillance system, the effect of management and supervision can be improved, and the probability of major accidents can be reduced. However, with the advent of the Internet of Things (IoT) era, video surveillance systems will face challenges such as massive equipment access, massive data, insufficient bandwidth, vulnerable to attack, and real-time monitoring difficulties. Based on the analysis of the research and application status of video surveillance system, we propose a video surveillance system based on permissioned blockchains (BCs) and edge computing. The system uses permissioned BCs, edge computing, InterPlanetary File System (IPFS) technology and convolution neural networks (CNNs). The edge computing is used to achieve large-scale wireless sensor information acquisition and data processing. IPFS storage service is used to realize massive video data storage, and CNNs technology is used to realize real-time monitoring.
In this paper, we present Tendermint: a Byzantine Fault Tolerant (BFT) application-based blockchain. We show that Tendermint promotes another perception of blockchain programming. Unlike Ethereum which is a blockchain holding many applications, Tendermint proposes to have one application per blockchain. We discuss the idiosyncrasies of Tendermint and how it could, potentially, ease blockchain programming and improve performance. We finish by showing weaknesses of Tendermint, good practices to adopt to hinder security attacks when handling Tendermint nodes, and some potential adjustments in the IBC protocol - an interoperability protocol designed for Tendermint. Our goal is to introduce Tendermint by showing its main characteristics over traditional blockchain platforms such as Bitcoin or Ethereum.

Crowd-intelligence tries to gather, process, infer and ascertain massive useful information by utilizing the intelligence of crowds or distributed computers, which has great potential in Industrial Internet of Things (IIoT). A crowd-intelligence ecosystem involves three stakeholders, namely the platform, workers (e.g., individuals, sensors or processors), and task publisher. The stakeholders have no mutual trust but interest conflict, which means bad cooperation of them. Due to lack of trust, transferring raw data (e.g., pictures or video clips) between publisher and workers requires the remote platform center to serve as a relay node, which implies network congestion. First we use a reward-penalty model to align the incentives of stakeholders. Then the predefined rules are implemented using blockchain smart contract on many edge servers of the mobile edge computing network, which together function as a trustless hybrid human-machine crowd-intelligence platform. As edge servers are near to workers and publisher, network congestion can be effectively improved. Further, we proved the existence of the only one strong Nash equilibrium, which can maximize the interests of involved edge servers and make the ecosystem bigger. Theoretical analysis and experiments validate the proposed method respectively.
BACKGROUND Huge amounts of health-related data are generated every moment with the rapid development of Internet of Things (IoT) and wearable technologies. These big health data contain great value and can bring benefit to all stakeholders in the health care ecosystem. Currently, most of these data are siloed and fragmented in different health care systems or public and private databases. It prevents the fulfillment of intelligent health care inspired by these big data. Security and privacy concerns and the lack of ensured authenticity trails of data bring even more obstacles to health data sharing. With a decentralized and consensus-driven nature, distributed ledger technologies (DLTs) provide reliable solutions such as blockchain, Ethereum, and IOTA Tangle to facilitate the health care data sharing. OBJECTIVE This study aimed to develop a health-related data sharing system by integrating IoT and DLT to enable secure, fee-less, tamper-resistant, highly-scalable, and granularly-controllable health data exchange, as well as build a prototype and conduct experiments to verify the feasibility of the proposed solution. METHODS The health-related data are generated by 2 types of IoT devices: wearable devices and stationary air quality sensors. The data sharing mechanism is enabled by IOTA’s distributed ledger, the Tangle, which is a directed acyclic graph. Masked Authenticated Messaging (MAM) is adopted to facilitate data communications among different parties. Merkle Hash Tree is used for data encryption and verification. RESULTS A prototype system was built according to the proposed solution. It uses a smartwatch and multiple air sensors as the sensing layer; a smartphone and a single-board computer (Raspberry Pi) as the gateway; and a local server for data publishing. The prototype was applied to the remote diagnosis of tremor disease. The results proved that the solution could enable costless data integrity and flexible access management during data sharing. CONCLUSIONS DLT integrated with IoT technologies could greatly improve the health-related data sharing. The proposed solution based on IOTA Tangle and MAM could overcome many challenges faced by other traditional blockchain-based solutions in terms of cost, efficiency, scalability, and flexibility in data access management. This study also showed the possibility of fully decentralized health data sharing by replacing the local server with edge computing devices.

Blockchain, the technology of the future neutrally facilitated the financial transactions in cryptocurrencies by strictly eliminating the need for a governing authority or a management that was required to authorize the transactions based on trust and transparency. The Blockchain Network also follows the principle of absolute privacy and anonymity on the identification of the users associated in a transaction. Since the time of its inception, the Blockchain Technology has undergone research that has demonstrated some various kinds of methods to sort out the access control system of the conventional system. In recent years Blockchain has also shown optimum reliability in multiple sectors such as Smart Home, Healthcare, Banking, Information Storage Management, Security and etc. This work in terms is further concerned to the sector of Smart Healthcare, which has grown to a much affluence regarding the efficient technique of serving and dictating medical health care to the patients with the point of maintaining privacy of the patients' data and also the process of laying out real time accurate and trusted data to the medical practitioners. But in the scenario of Smart Healthcare, the primary concern arises in the fact of Privacy and Security of the data of the patients due to the interoperability of multiple stakeholders in the process. Also, there has been a fact of determining accurate and proper data to the doctors if the concerned subject is out of reach from the in hand medical service. Therefore, this Concern of privacy and also mitigation of the accurate data has been very much managed in the work by regulating, a monitoring and sensing paradigm with accordance to the IOT and the Blockchain as a transaction and access management system and also an appropriate medium for laying out accurate and trusted data for serving with deliberate medical care and benefits to the patients across.
A Smart Contract is self-executable and self-enforceable program code that runs on the top of blockchain to manage complex business logic. It eliminates the need of extrinsic enforcement of legal agreements. Furthermore, it enforces the terms and conditions of an agreement that lies between untrustworthy parties in which the trusted third parties cannot interfere. The cryptography logic used in smart contract enables the blockchain network to provide trust and authority to all parties in transaction. Network decentralization, data immutability and transparency, resiliency and security make blockchain technology more versatile. Recently, it has become a potential quality and capability of IoT to connect uncountable electronic objects or devices at the same time. The most prominent feature of blockchain-based IoT applications is the integration of smart contracts between blockchain and IoT.A brief comparison has been given in the paper that how the smart contracts react on multiple blockchain platforms with respect to scalability, system complexity and consensus protocol factors. Furthermore, the context of Smart contract integration between blockchain and IoT with highlighting the integration opportunities and challenges along with future research directions. Therefore, we have concluded in the current paper that amalgamation of Blockchain with IoT through Smart Contract can provide a strong framework for distributed application and the newly introduced business communities.
Emergency service call for public service providers has become an important role for smart home applications in order to support safety and security in the household building. Blockchain has been a promising solution with cryptography and incentive distributed mechanisms to support the verification, execution and recording of transactions between untrusted parties. In this paper, we present a Smart Home System (SHS) based on Ethereum with smart contract infrastructure for handling an emergency service sending from SHS to Home Service Providers (HSP) when there are unusual environmental conditions. Our SHS testbed consists of three domains: (1) Smart Home Sensor Manager (SM) or IoT devices to gather environmental sensor data and send an emergency call to HSP, (2) Home Service Provider (HSP) system deployed with Ethereum Virtual Machine (EVM) and smart contract, and (3) decentralize Meteor framework to interface between Ethereum and web based applications for homeowners (HO) and HSP staffs. To achieve homeowner privacy and security, we enable digital signature coupling with InterPlanetary File System (IPFS) for handling the emergency call from SM to HSP and One Time Passcode (OTP) produced by HSP for HSP staffs to verify themselves for further access control when they go to service homeowner's house. Each smart contract transaction in solidity is described. Finally, security and privacy issues for our proposed work are discussed.

The recent, exponential rise in adoption of the most disparate Internet of Things (IoT) devices and technologies has reached also Water supply chains, drumming up substantial research and innovation interest towards developing reliable, auditable and transparent traceability systems. Current IoT-based traceability and provenance systems for water supply chains are built on top of centralized infrastructures and this leaves room for unsolved issues and major concerns, including data integrity, tampering and single points of failure. Blockchains, the distributed ledger technology underpinning cryptocurrencies such as Bitcoin, represent a new and innovative technological approach to realizing decentralized trustless systems. This will also eliminate corruption due to unmaintained record of sources. Indeed, the inherent properties of this digital technology provide fault-tolerance, immutability, transparency and full traceability of the stored transaction records, as well as coherent digital representations of physical assets and autonomous transaction executions. This paper presents Aqua-chain, a fully decentralized, blockchain-based traceability solution for Water supply chain management, able to seamless integrate IoT devices producing and consuming digital data along the chain. To effectively assess Aqua-chain, first, we defined a classical use-case within the given vertical domain, namely from-supplier-to-buyer. Then, we developed and deployed such use-case, achieving traceability using blockchain implementation, Ethereum. Finally, we evaluated and compared the performance deployments, in terms of latency, CPU, and network usage, also highlighting its main pros and cons.
So far Internet has connected humans and now with technological advancements it is inter connecting `Things'. With more globalization and technological advancement, The Internet of Things (IoT) has been matured into self sustaining and evolving technology that has the capacity to change the way how physical and cyber worlds interact. We can also say IoT is about anything that can connect everything. With Involvement of Global Corporations, new IoT-based systems are being proposed in almost every sector which humans have so far envisioned. The thoughts (or Science Fiction) which was once fictional and unbelievable are becoming reality, whatever we desire will be available at touch of our finger someday. Mankind is moving fast towards connected future, where not only autonomous vehicles but entire cities infrastructure will be completely internet connected to support rapid urbanization. To reap the full benefit of IoT, it is imperative that the infrastructure we depend upon is adequate to deliver the services envisioned and has the necessary resilience, robustness and security. IoT can be described as an large scale, heterogeneous, ultra-complex Ecosystem acting as bridge between cyber and physical worlds. Recently, the Distributed Ledger Technology (Blockchain and Block less-different implementation of Data Structures with cryptographic algorithmic functions) has gained much attention in IoT solutions from security perspective. In This Research Paper we have explained the concepts about the functioning of Distributed Ledger Technology with focus on how it can provide security (for System Resiliency) in IoT Ecosystem.

Blockchain has attracted a broad range of interests from start-ups, enterprises and governments to build next generation applications in a decentralized manner. Similar to cloud platforms, a single blockchain-based system may need to serve multiple tenants simultaneously. However, design of multi-tenant blockchain-based systems is challenging to architects in terms of data and performance isolation, as well as scalability. First, tenants must not be able to read other tenants' data and tenants with potentially higher workload should not affect read/write performance of other tenants. Second, multi-tenant blockchain-based systems usually require both scalability for each individual tenant and scalability with number of tenants. Therefore, in this paper, we propose a scalable platform architecture for multi-tenant blockchain-based systems to ensure data integrity while maintaining data privacy and performance isolation. In the proposed architecture, each tenant has an individual permissioned blockchain to maintain their own data and smart contracts. All tenant chains are anchored into a main chain, in a way that minimizes cost and load overheads. The proposed architecture has been implemented in a proof-of-concept prototype with our industry partner, Laava ID Pty Ltd (Laava). We evaluate our proposal in a three-fold way: fulfilment of the identified requirements, qualitative comparison with design alternatives, and quantitative analysis. The evaluation results show that the proposed architecture can achieve data integrity, performance isolation, data privacy, configuration flexibility, availability, cost efficiency and scalability.

It examines Use Cases and benefits of current IoT and Blockchain integrated frameworks for SCM. It also explores limitations of the traditional IoT and Blockchain integration patterns and presents an architectural framework for a permissioned Blockchain that can be used to overcome these limitations.
BACKGROUND Health care professionals are required to maintain accurate health records of patients. Furthermore, these records should be shared across different health care organizations for professionals to have a complete review of medical history and avoid missing important information. Nowadays, health care providers use electronic health records (EHRs) as a key to the implementation of these goals and delivery of quality care. However, there are technical and legal hurdles that prevent the adoption of these systems, such as concerns about performance and privacy issues. OBJECTIVE This study aimed to build and evaluate an experimental blockchain for EHRs, named HealthChain, which overcomes the disadvantages of traditional EHR systems. METHODS HealthChain is built based on consortium blockchain technology. Specifically, three organizations, namely hospitals, insurance providers, and governmental agencies, form a consortium that operates under a governance model, which enforces the business logic agreed by all participants. Every peer node hosts an instance of the distributed ledger consisting of EHRs and an instance of chaincode regulating the permissions of participants. Designated orderers establish consensus on the order of EHRs and then disseminate blocks to peers. RESULTS HealthChain achieves functional and nonfunctional requirements. It can store EHRs in a distributed ledger and share them among different participants. Moreover, it demonstrates superior features, such as privacy preservation, security, and high throughput. These are the main reasons why HealthChain is proposed. CONCLUSIONS Consortium blockchain technology can help to build new EHR systems and solve the problems that prevent the adoption of traditional systems.
IoT is a new communication paradigm that gains a very high importance in the past few years. This communication paradigm supports various heterogeneous applications in many fields and with the dramatic increase of the number of sensor devices, it becomes a demand. Designing IoT networks faces many challenges that include security, massive traffic, high availability, high reliability and energy constraints. Thus, new communication technologies and paradigms should be deployed for IoT networks to overcome these challenges and achieve high system performance. Distributed computing techniques (e.g. fog and MEC), software defined networking (SDN), network virtualization and blockchain are common recent paradigms that should be deployed for IoT networks, either combined or individually, to achieve the main requirements of the IoT networks at a high system performance. Fog computing is a form of edge computing that has been developed to provide the computing capabilities (e.g. storage and processing) at the edge of the access network. Employing Fog computing in IoT networks, as an intermediate layer between IoT devices and the remote cloud, becomes a demand to make use of the edge computing benefits. In this work, we provide a framework for the IoT system structure that employs an edge computing layer of Fog nodes controlled and managed by SDN network with the blockchain technology to achieve a high level of security for latency sensitive IoT applications. The proposed system employs SDN network with distributed controllers and distributed OpenFlow switches; these switches are enabled with limited computing and processing capabilities. Furthermore, a data offloading algorithm is developed to allocate different processing and computing tasks to the distributed OpenFlow switches with available resources. Moreover, a traffic model is proposed to model and analyze the traffic among different parts of the network. The proposed work achieves various benefits to the IoT network, such as the latency reduction, security improvement and high efficiency of resources utilization. The proposed algorithm is simulated and also the proposed system is experimentally tested over a developed testbed to validate the proposed structure. Experimental results show that the proposed system achieves higher efficiency in terms of latency, security and resource utilization.
In recent years, the status of cooperation and innovation has become increasingly important. Research on the behavior of production, education, and research organizations has attracted widespread attention. Blockchain technology is considered as another subversive technology following cloud computing, wireless sensor networks, and big data. It is highly concerned by governments, financial institutions, and technology companies. Blockchain technology is essentially a technical solution that collectively maintains a reliable database through a decentralized, high-trust way. Blockchain WEB technology has not only used in financial and other fields, but also has a great potential for application in the fields of production, education, and research. It has expected to play an important role in the establishment of a trust mechanism in the “Internet +” production, research, and innovation and promote education. Drawing on the experience in blockchain applications in the financial sector, the blockchain in the education sector mainly embodies six application modes: building individual science credit data, creating an intelligent education Taobao platform, developing a degree certificate system, and building a new ecology of open educational resources. Of course, due to the uniqueness and complexity of the trust field in the cooperation innovation of industry, universities, and research institutes, the application of blockchain technology is also faced with difficulties in the application, promotion, and operation of production and research, fuzzy ownership of educational big data, limited data storage space, and potential safety problems of blockchain technology. There are many challenges such as the privacy protection risks of teachers and students.
Despite key advances in healthcare informatics and management, little progress to address supply chain process-related problems has been made to date. Specifically, key healthcare supply chain processes include product recalls, monitoring of product supply shortages, expiration, and counterfeits. Implementing and executing these processes in a trusted, secure, efficient, globally accessible and traceable manner is challenging due to the fragmented nature of the healthcare supply chain, which is prone to systemic errors and redundant efforts that may compromise patient safety and impact health outcomes adversely. Blockchain, combined with the Internet of things (IoT), is an emerging technology that can offer a practical solution to these challenges. Accordingly, IoT blockchain offers a superior way to track and trace products via a peer-to-peer distributed, secure, and shared ledger of the blockchain network. This article highlights key challenges related to healthcare supply chains, and illustrates how IoT blockchain technologies can play a role in overcoming these challenges now and in the near future.
