Abstract

This paper proposes DIMSEPP, a decentralized identity management system that enhances privacy while preserving blockchain verifiability. The system cryptographically enforces data minimal disclosure principles by storing attribute commitments on-chain and validating them through zero-knowledge proofs, allowing users to demonstrate attribute validity without revealing sensitive values. The architecture maintains full compatibility with existing DID standards through standard document structures and verification methods. Security analysis demonstrates provable guarantees under standard cryptographic assumptions. Practical evaluation confirms the system's efficiency for resource-constrained environments, supporting deployment in applications where both privacy and verifiability are essential.
