A2-DIDM: Privacy-preserving Accumulator-enabled Auditing for Distributed Identity of DNN Model

Researchers propose A2-DIDM, a blockchain-based system using zero-knowledge proofs and cryptographic accumulators to verify DNN model ownership and prevent unauthorized replication in the growing AI model trading market. The scheme enables lightweight on-chain identity verification while preserving data and function privacy through weight checkpoint authentication.
