Enhancing User Privacy in Decentralized Identity Management: A Comparative Analysis of Zero-Knowledge Proofs and Anonymization Techniques on Blockchain Infrastructures
Keywords:
Blockchain technology, Self-sovereign identityAbstract
Rising digital identity management requires strong privacy and security. Online interactions need centralised identity management systems, but their flaws and lack of user control over personal data pose security threats. Common data breaches allow centralized authority to modify or exploit IDs. Blockchain's unchangeable ledger and universal consensus enable self-sovereign identification. These systems safeguard identities and provide dependents optional verification. BC-IMS privacy issues remain. A research examines ZKPs and anonymity. BC-IMS weighs these approaches' pros and cons.
