A family health management system deals with a safe and secure way of managing family member health details such as illness diagnosis, treatment, medical prescriptions, medical reports, and life insurance policies. All health records are encrypted and stored in chronological order utilizing blockchain technology so that authenticity, integrity, security, and privacy of the records are safeguarded. All stages of medical treatment are documented and stored for ease of future reference by the family. This becomes very handy if a person changes doctors and/or relocates to some other place/country for varied reasons. All the necessary health reports are shared with the life insurance company so that insurance claims become hassle free, if applicable. Medicine details are cross-verified with the manufactures to avoid fake drugs. This chapter explores the compatibility of using ethereum with the interactive MyEtherWallet to implement the proposed model.
Chapter Preview


Emerging technologies, as described by Industry 4.0, include emerging business and financial possibilities for healthcare networks. As per the Computing Technology Industry Association (CompTIA), the world's top 10 emerging innovations in 2019 were the Internet of Things (IoT), artificial intelligence, 5/6g Networks, server-less Computing, Blockchain, Robots, Biometry, 3D Printing, Augmented Reality/Virtual Reality, and Drones

Blockchain technology is a peer network for transferring digital assets and data without any hassle intermediate technologies and supports the popular crypto currency bitcoin. Bitcoin was first announced in 2008 and implemented by Nakamoto in 2009 (Rayome, 2019). The chain will continue to grow when new blocks are added. All transactions occur in a decentralized manner, eliminating the need for any intermediaries to verify transactions (Tsai et al., 2016). Blockchain has some key features, such as decentralization, transparency, variability and adaptability. Blockchain operates in a decentralized environment and employs digital signatures, cryptographic hash and distributed core technologies, consensus mechanisms.

Blockchain architecture


The blockchain network has a decentralized information system (Meng et al., 2018; Gipp et al., 2016) contain information about past transactions. It specifies the method for performing and checking transactions, as well as the overall functioning of the network and its participants (Mehdi et al., 2017). The term “distributed registry data” is often used to describe this network. Each node that works on a specific network is saved (Suveen et al., 2017; Ahram et al., 2017). The previous block hash record is used to connect transaction information to the chain on blockchain networks (Ovais, 2017).

Taxonomy of Blockchain Systems

Current blockchain networks are classified into four forms of blockchains: private, public and hybrid.

Public Blockchains: The public blockchains have a completely decentralized network, where all participants can access and participate in the consensus process blockchain material (e.g. Bitcoin and Ethereum.)

Private Blockchains: private block chains are used to track data transfers between various departments and individuals, who are devoted to single enterprise solutions. Each participant requires permission to be a member of the network as soon as it is a known member.

Consortium Blockchains: A blockchain consortium is a network approved and publicly accessible to a privileged community only. It can be used to track participant data exchanges as an auditable and securely synchronized distributed database.

Hybrid Blockchains: hybrid blockchains merge privately and publicly. A public blockchain is then used to make the headline fully visible, with a private blockchain running behind the header which can control access to the changes in the header.

Blockchain Components

The technology of Blockchain consists of many components that work together. Blockchain technology will make its users such guarantees by bringing these components together.


Blockchain is an immutable record or digital record at the most basic level. A record keeping infrastructure that enables the guides of the blockchain to say a story is the heart of the blockchain. This story typically focuses on asset ownership and history, although leads can be used to record almost any conceivable data.
