Network setup model over a private blockchain network dealing with security issues

Abstract

This chapter addresses how getting data privacy in the world of centralised identification systems today is a myth because of its many problems, the primary one being data control by one single entity. Self-Sovereign Identity (SSI) is a model that allows its utilisers complete control over their data privacy and security. This paper gives an overview of developing such a model over a private blockchain network using several Hyperledger frameworks, which are majorly open source. Hyperledger Indy is crucial as it is an open-source public decentralised distributed ledger technology (DLT). Hyperledger Aries is used to interact with nodes, access them, and read and write data on the ledger. Hyperledger Ursa is used to avoid the double spending problem by employing blockchain cryptography.
