Decentralized Digital Identity Verification System Using Blockchain Technology

Abstract

Decentralized digital identity verification systems based on blockchain technology, or D.D.I.V.S as they are popularly known, are linchpins for an entirely new way of authenticating our online identities. These systems possess a number of obvious merits compared to the traditional methods of identity verification, for instance elevated security level, privacy protection and practicability. This article introduces a Prototype system using MetaMask, a very well-known cryptocurrency wallet and Web3 gateway. The system offers significantly superior results than traditional approaches. Its parts include user registration and data extraction by means of public key registration, secure key storage with MetaMask, an uninterrupted connection between D-Apps (Decentralized Applications) and the wallet; and application of asymmetric cryptography to data encryption and decryption. Strict testing has confirmed the MetaMask-powered prototype system can provide a secure, private and practical decentralized digital identification verification platform. That heralds a promising change for all of us
