Authentication System and Authorization System Using Blockchain Technology

Blockchain technology has experienced a tremendous increase in popularity in recent years due to its potential to change a number of industries, including finance, healthcare, and logistics. One of the key features of blockchain technology is its capacity to provide safe authentication and permission. In order to maintain and verify identities and rights, traditional authentication and authorization techniques rely on a centralised authority. However, this strategy has a number of shortcomings, including single points of failure, security flaws, and constrained scalability. A decentralised, secure method of maintaining identities and permissions is provided by blockchain technology. The development of a transparent, impenetrable record of all transactions and data is made possible by blockchain technology. The positives of adopting blockchain technology for authentication and authorisation over more traditional methods are examined in this article, along with its cons and potential applications. This study contributes to the evolving discourse on blockchain technology by specifically examining its applications in authentication and authorization systems. By investigating the strengths and weaknesses of this decentralized approach, we aim to provide valuable insights for researchers, practitioners, and decision-makers seeking to harness the full potential of blockchain in enhancing security and transparency in identity management.
