摘要
针对联盟链协作中敏感信息披露与业务验证并存的需求，构建基于零知识证明的可验证隐私保护模型，并在 Hyperledger Fabric 上实现原型。模型从内容、身份及元数据与操作关系三个维度组织问题，以消息可验证承诺、交易内容机密性、接收方身份保护和发送方身份保护四个子方案协调既有密码学机制。完整 Marlin 验证置于链下，链码检查授权服务签名及状态条件，状态更新以有效提交为前提。历史功能报告记录 11 类测试、41 个有效用例；系统测试中基础流程与完整隐私流程的平均采样时间分别为 130 ms 和 352 ms。独立协议实验描述了三种所测配置的成本差异。结果支持限定场景下的流程可执行性，但采样时间不能确认为有效提交延迟，也不能分解为单一组件开销。该模型为联盟链中减少直接披露并保留验证证据提供了原型实现，不构成绝对匿名或普遍安全保证。
Abstract
To address the coexistence of sensitive-information disclosure and business verification in consortium-blockchain collaboration, a verifiable privacy-preserving model based on zero-knowledge proofs is developed and implemented as a Hyperledger Fabric prototype. The model organizes the problem into content privacy, identity privacy, and control of metadata and operational-relation exposure. Four sub-schemes-verifiable message commitment, transaction-content confidentiality, receiver identity protection, and sender identity protection-coordinate established cryptographic mechanisms. Full Marlin verification is performed off-chain; chaincode checks the authorized service\'s signature and state conditions, and state updates require a valid commit. Historical functional reports record 11 test categories and 41 valid cases. System tests report mean sampler times of 130 ms for the baseline flow and 352 ms for the complete privacy flow. Independent protocol experiments describe cost differences among three tested configurations. These results support workflow executability within the tested scope, but sampler times cannot be confirmed as valid-commit latency or decomposed into individual-component costs. The model provides a prototype implementation for reducing direct disclosure while retaining verification evidence in consortium blockchains; it does not establish absolute anonymity or universal security.关键词
