Abstract
The way people prove who they are online is
changing. Traditional internet identity systems, whether centralized or
federated, place control in the hands of companies or governments, leaving
users dependent on those entities for access, security, and privacy. This paper
explores blockchain-based internet identity management as a response to those
limitations. It examines the three main models which are centralized,
federated, and self-sovereign and also explains how each uses blockchain to
enhance trust, verification, and data integrity. Case studies, including
Sovrin, uPort, and Civic, illustrate how these systems work in practice and the
trade-offs they present. The discussion also covers regulatory and ethical
considerations, such as compliance with GDPR and the protection of privacy
rights, as well as technical enablers like decentralized identifiers (DIDs) and
verifiable credentials. While blockchain offers transparency, immutability, and
decentralization, adoption challenges remain, particularly around interoperability,
user key management, and policy alignment. The paper concludes by outlining
future directions, including cross-platform standards, privacy-preserving
verification methods, integration with national ID programs, and user-friendly
security approaches. The findings suggest that blockchain identity systems have
the potential to shift control toward individuals while improving security, but
their success depends on careful governance, global cooperation, and practical
usability.
