DigiBlock: Digital Self-sovereign Identity on Distributed Ledger based on Blockchain

With the rise of the digital era, the massive shift towards everything being digital is evident. People have a plethora of digital data points to denote them in digital world. Digital personal data points, also known as Digital Identity, contains Personally Identifiable Information (PII) which is private to every individual. Managing the cycle of private, high security data from its creation till verification is a massive undertaking. As there are instances where personal data are breached, centralized servers fail to respond, attacks compromise the entire system, it becomes difficult to rely on such systems. Blockchain is a propitious technology that is immutable, decentralized, tamper-proof, highly secure and easy to use. This paper proposes to use Blockchain and leverage its advantages to establish a self-sovereign digital identity management system, collision resistant encrypted document, which ensures the integrity of document issued. It presents DigiBlock as a powerful solution to the current scenario with a robust role based permission system leveraging Distributed Ledger Technology (DLT), which provides advantage over centralized system with its exceptional sovereignty, storage-control, cost-free, security, privacy, transparency and portability features.
