摘要

摘要: 针对隐私众包场景下出现的数据验证、匿名作恶检测和跨平台资源交互等需求，该文基于区块链技术，并结合零知识证明与环签名技术，提出一种联盟链架构下的隐私众包方案。该方案依靠零知识证明实现对加密数据的验证，依靠链接可撤销环签名改进方案实现工人身份的可控匿名，引入联盟链架构实现众包实体之间的资源交互。在完成众包完整流程的同时，实现隐私众包所需的数据保护与身份保护。安全性分析表明，该方案具有隐私性、可验证性、可控匿名性与公平性。实验结果验证了方案在效率与性能方面的有效性。

Abstract: Considering the requirements of data verification, anonymous malicious behavior detection and cross-platform resource interaction in privacy crowdsourcing, a scheme under the consortium chain architecture is proposed, basing on blockchain technology with zero-knowledge proof and ring signature technology. The proposed scheme relies on zero-knowledge proof to achieve encrypted data verification, relies on improved revocable-iff-linked ring signature to achieve controllable anonymity of workers, introduces consortium chain to realize resource interaction between crowdsourcing entities. In addition to completing the crowdsourcing process, the scheme also implements data protection and identity protection required for privacy crowdsourcing. Security analysis shows that the proposed scheme satisfies privacy, verifiability, controllable anonymity and fairness. Experimental results verify the advantages of the proposed scheme in efficiency and performance.
