Research on Access Control and Transaction Delivery of Cultural Resource Based on Smart Contract and Zero- Knowledge Proof

Abstract

In the context of cultural resource big data sharing and trading, existing practices face challenges such as coarse-grained permission management, privacy leakage during data delivery, and insufficient process automation. To address these issues, this paper proposes an integrated solution for permission management and automated transaction delivery. First, a multi-dimensional attribute permission model (MDAPM) for cultural resources is introduced, which leverages fuzzy mathematics and smart contracts to achieve dynamic authorization across the three dimensions of user, resource, and context, while incorporating zero-knowledge proofs (ZKP) to mitigate privacy leakage in permission verification. Second, a permission-data-address coupled delivery framework (PDACPF) is designed, which integrates the consortium blockchain and the interPlanetary file system (IPFS) for distributed storage to enable end-to-end automation of cultural resource data management, from preprocessing and transaction triggering through secure delivery. Simulation results demonstrate that under a lOO-concurrency scenario, the solution achieves a permission adjustment response time of less than 0.8 s, a data delivery success rate of at least 99.9%, and reduces privacy leakage risk to zero, thereby effectively supporting standardized trading and sharing of cultural resource big data.
