A Review of Blockchain based Decentralised Authentication Solutions and their improvement through Metamask

With the advancing technology, it becomes difficult to cope up with novel trends and configurations. Similarly, it is difficult to secure the systems against each emerging threat. With this the loopholes in conventional forms of system security based on centralized format are now visible. Hence there are explorations in various alternatives of centralized system authentication and authorization. Blockchain technology has appeared as a means of securing the systems as it works on decentralization thereby by passing the loopholes that exist in centralized authentication. Hence, this study lays down the recent advancements in the field of blockchain authorization and authentication techniques. It further supplements the study with an explanation of MetaMask extension which connects the user to the blockchain network thereby enabling decentralization in system security. This study further proposes the future potentials of MetaMask and blockchain integration.
