A Self-Sovereign Identity Framework for Context-Aware De-Centralized Identifier Creation and Credential Verification

Digital Identity is a key concept in the digital era.It is very important as it impacts how we interact, transact, and secure our information online.Several systems, like Federated and User-centric, are the basis for digital identity management.We must enhance this identity for data security and integrity.It is necessary for strengthening an identity system.A digital Identity concept known as Self-Sovereign Identity allows users to fully own their identification related data without depending on central authority.It is a strong contender for an efficient identity management system.SSI's strengths are its full ownership and selective disclosure of user credentials, without a third party verification.SSI uses Decentralized Identifiers as unique Identifiers.It uses encrypted identity proof via Verifiable Credentials.A peer-to-peer distributed file system called the InterPlanetary File System (IPFS) makes it possible to store and share data in a decentralized, content-addressable way.Verifiable credentials are stored on IPFS, which eliminates the need for centralized servers and provides decentralized, permanent, and tamper-resistant storage.This work also uses zk-SNARKs to selectively disclose identity-related information.This paper proposes a new Digital Identity Management framework.It is based on SSI methodology and principles.The work has the Blockchain as its core network.It gives strong security and integrity to the user identity data.Also, the proposed approach is validated against state-of-art Identity management systems.
