AB - As streaming-centric music distribution grows, revenues are shared among multiple rights holders based on agreed equity ratios. However, opaque platform operations make verifying settlement accuracy difficult for these rights holders. While blockchain solutions can offer transparency, they risk exposing detailed usage logs and sensitive contract terms, leading to privacy and trade secret leaks. To resolve this, this paper proposes a privacy-preserving verification system utilizing zero-knowledge proofs (ZKP) and secret sharing schemes (SSS). By distributing contract terms across independent nodes via secret sharing, verification operations are executed only upon threshold approval. Large-scale source logs are compressed and pseudonymized using a Merkle tree, allowing the system to prove the consistency of settlement rules through a single proof without revealing raw data. This approach successfully ensures confidentiality, collusion resistance, and verifiability. A Hyperledger Fabric-based prototype demonstrated constant performance regardless of data size, achieving approximately 0.87 ms on-chain verification time and under 1 KB transmission size even for 1 million logs.
