Blockchain and IoT Integration in Dairy Production to Survive the COVID-19 Situation in Sri Lanka

The epidemic crises place massive burdens on our economies. The risk of food supplies is also pushing massive stress on food vendors around the world. There are big problems associated with supply chains framework. Farmers do not receive payment upon delivery of their supplies. The buyers do not have access to finance that will enable them to pay farmers on time. To solve this problem, the authors proposed a dairy production system integration with blockchain and IoT. Blockchain is a decentralized digital ledger technology that allows network participants to trust each other and interact. The dairy product system can check the temperature of the product in real-time by using the website application. Moreover, customers can get notifications when the policy found problems related to temperature values. The blockchain database confirms the information security of the system by using the proof of work algorithm to create the transactions and the blocks. Therefore, the proposed methods can use sensitive data with reasonable time consumption, and no block creation fees are needed.

Security and Privacy for Electronic Healthcare Records Using AI in Blockchain

In yesteryears, the healthcare data related to each patient was limited. It was stored and controlled by the hospital authorities and was seldom regulated. With the increase in awareness and technology, the amount of medical data per person has increased exponentially. All this data is essential for the correct diagnosis of the patient. The patients also want access to their data to seek medical advice from different doctors. This raises several challenges like security, privacy, data regulation, etc. As health-related data are privacy-sensitive, the increase in data stored increases the risk of data exposure. Data availability and privacy are essential in healthcare. The availability of correct information is critical for the treatment of the patient. Information not easily accessed by the patients also complicates seeking medical advice from different hospitals. However, if data is easily accessible to everyone, it makes privacy and security difficult. Blockchains to store and secure data will not only ensure data privacy but will also provide a common method of data regulation.
Millennials vs. Cyborgs and Blockchain Role in Trust and Privacy

Over recent years, technology has rapidly advanced and is accelerating the emergence to Industry 4.0, particularly due to the connectivity abundance, volume increase of smart devices, and a growing interconnectivity between humans and technology.

A Reliable IDS System Using Blockchain for SDN-Enabled IIoT Systems

The internet of things is the technology that aims to provide a common platform to the devices of varying capabilities to communicate. Industrial internet of things (IIoT) systems can perform better using these devices in combination with SDN network and blockchain technology. The suggestion uses random space learning (RSL) comprising three stages. The random subspace learning strategy is a troupe learning procedure called attributes bagging. It improves forecast and order errands as it utilizes group development of base classifiers rather than a solitary classifier, and it takes arbitrary subsets of properties rather than the whole arrangement of attributes. The system uses the blockchain methodology to secure the system. SDN networks aim to better the transmission of data in industrial IoT devices. Misrouting and forged attacks are some of the common attacks in these systems. The proposal provides better reliability than the previous contribution by 2.7%.
Blockchain Technology-Security Booster

“Blockchain” as the name suggests is the chain of blocks. It is the chunk of digital information (blocks) that are connected through the public databases (Chain). It is nothing but the newer version of file organisation. Blocks store digital information like actual record of any transaction, details of involve entities in the transaction, time stamps, and other metadata of the transactions. Blocks also have unique ids, which are known as hash. Blockchain technology is built using peer-to-peer networking. Anyone who is on network can access the blocks. There is no centralised community to control the blockchain. It is operated by miners, the peoples who lend their computing power to the network to solve the complex computation algorithm problems. These blocks are stored in multiple computers. Due to its distribution and decentralisation, the validation process is broadcast in nature, which provides it “the trusted approach”. Blockchain enables security and tamperproof capabilities for storing data and smart contracts. Any tampering of data attempted by a node or user in a block changes the hash of the block. The blockchain technology has the capability to face and provides the solution to fight with the problem of risk and security concern online. In 2008, a mysterious white paper titled “Bitcoin: A Peer to Peer Electronic Cash System”, by visionary Satoshi Nakamoto gave birth to the concept of blockchain. The chapter explains the structure of blockchain technology in detail and enlighten the aspects that make blockchain technology the secure concept of today's world.

Decentralizing Privacy Using Blockchain to Protect Private Data and Challanges With IPFS

Blockchain technology is a distributed framework for sharing data that is validated through cryptographic functions. The nodes of the network come to a consensus regarding addition of data to the blockchain. Every blockchain operation requires a processing fee. This fee makes storing of large data on the blockchain infeasible. An indirect alternative for this challenge could be use of IPFS, which is a decentralized peer-peer network that facilitates storage of file. This is accomplished by storing the hash of the IPFS as data on the blockchain.

Consequent Formation in Security With Blockchain in Digital Transformation

Blockchain technology makes use of a centralized, peer-to-peer (P2P) network of databases, also called nodes, to validate and record digital transactions between individual users located anywhere across the globe. These transactions often take place through the exchange of cryptocurrencies such as bitcoins, Ethereum, and Ripple, etc. The security and transparency that is inherently present in digital transactions place blockchain technology in high demand across various industrial applications. Each node updates its database in real-time as and when transactions occur. The transaction gets authorized only when a majority of the nodes in the network validate the transaction. Once the verification is complete, a block, consisting of hash and keys, is generated for each new transaction and is linked to previous transactions in every database. Every node updates its database with the new block. A hacker would have to break down every node in the system to commit fraud. Blockchain could play a major role in maintaining the cyber security of digital transactions in the future.
