论文摘要
隐私保护是各个部门的主要关注点。为了保护各个用户数据，一项新兴技术是差异隐私。但是，它仍然对具有频繁查询的数据集有局限性，例如隐私成本的快速积累。为了应对这一限制，本文探讨了有担保分散分类帐区块链的整合。区块链将能够跟踪所有具有差异隐私算法产生的嘈杂响应，并允许某些查询重复使用旧响应。在本文中，针对基于区块链的隐私管理系统的演示设计为交互式分散的Web应用程序（DAPP）。创建的演示表明，在区块链上的利用将允许累积的总隐私成本大大减少。
Privacy preservation is a big concern for various sectors. To protect individual user data, one emerging technology is differential privacy. However, it still has limitations for datasets with frequent queries, such as the fast accumulation of privacy cost. To tackle this limitation, this paper explores the integration of a secured decentralised ledger, blockchain. Blockchain will be able to keep track of all noisy responses generated with differential privacy algorithm and allow for certain queries to reuse old responses. In this paper, a demo of a proposed blockchain-based privacy management system is designed as an interactive decentralised web application (DApp). The demo created illustrates that leveraging on blockchain will allow the total privacy cost accumulated to decrease significantly.
