BSFarm: A blockchain-based secure supply chain automation for Smart Farm
Abstract
For decades, farming has been connected with the production of essential food crops. However, automation in farming is very critical. Moreover, the current automation process surrounds with data integrity, reliability, availability, and cyber threats. Blockchain is a data structure in which data are shared among peers. Blockchain holds properties like pseudonymity, data integrity, avialability, security. This paper proposed a blockchain enabled secure supply chain management of the smart firm in which production can not only be tracked easily but also managed the farm data securely in blockchain.

Unmanned aerial vehicle (UAV) is an emerging technology that becomes popular not only in military operation but also in civil applications. Internet of things (IoT) is another popular technology which brings automation in our daily life. Like other areas, IoT also exposes its potential in healthcare. Using IoT sensors, it becomes easy to monitor the health of a user remotely. UAV consolidated with mobile edge computing (MEC) can provide real-time services in outdoor health monitoring. However, communication among them surrounds with cyber threats and data integrity issue. Blockchain is a data structure in which data are shared among peers. In this paper, a blockchain based secure outdoor health monitoring scheme using UAV is proposed for a smart city. In the proposed scheme, health data (HD) are accumulated from users wearable sensors and these HD are transmitted to the nearest MEC server via UAV. Prior to transmitting to MEC, HD experience encryption in order to provide protection against cyber threats. Moreover, after arriving at MEC, HD are diagnosed and if any abnormalities are found in the user’s health, MEC server notifies the user and the nearest hospitals. When the processing is completed, HD are stored in blockchain with the consent of validators. Finally, simulation results and experimental set up are discussed in order to manifest the feasibility of the proposed scheme.
In order to stay up to date with world issues and cutting-edge technologies, the newspaper plays a crucial role. However, collecting news is not a very easy task. Currently, news publishers are collecting news from their correspondents through social networks, email, phone call, fax etc. and sometimes they buy news from the agencies. However, the existing news sharing networks may not provide security for data integrity and any third party may obstruct the regular flow of news sharing. Moreover, the existing news schemes are very vulnerable in case of disclosing the identity. Therefore, a universal platform is needed in the era of globalization where anyone can share and trade news from anywhere in the world securely, without the interference of third-party, and without disclosing the identity of an individual. Recently, blockchain has gained popularity because of its security mechanism over data, identity, etc. Blockchain enables a distributed way of managing transactions where each participant of the network holds the same copy of the transactions. Therefore, with the help of pseudonymity, fault-tolerance, immutability and the distributed structure of blockchain, a scheme (termed as NEWSTRADCOIN) is presented in this paper in which not only news can be shared securely but also anyone can earn money by selling news. The proposed NEWSTRADCOIN can provide a universal platform where publishers can directly obtain news from news-gatherers in a secure way by maintaining data integrity, without experiencing the interference of a third-party, and without disclosing the identity of the news gatherer and publishers.
Unmanned aerial vehicle (UAV) has been regarded as one of promising research field because of its capability of performing critical operations. Mobile Edge Computing (MEC) is an emerging technology where the cloud has brought to the base station and utilizes radio access network in order to meetup network challenges. UAV combined MEC can perform real-time activities. Internet of Underwater Things (IoUT) is a network of things which play a very important role in underwater monitoring and surveillance. However, UAV can provide better support to IoUT in terms of communication and energy saving while communicating with remote BS. However, communication from remote areas with IoUTs via UAV creates many cyber threats. Blockchain is another emerging technology which provides support in terms of data security, integrity etc. This paper presents a blockchain based secure scheme in which UAV is integrated with MEC in order to assist in underwater monitoring.
Internet of Things (IoT) imparts not only comfort to our life but also exposes new research areas like Social Internet of Things which can assist to manage things more efficiently. Another concept, Blockchain, is imparting in every research area because of its technology. In this context, the contribution of this paper follows: 1) we depict popular areas of SIoT, its current issues and how can Blockchain contributes to solving the issues; 2) we mention an issue regarding applying Blockchain into the SIoT
