随着越来越多的组织在工业物联网网络中部署其传感设备，组织与其他组织共享数据以充分挖掘数据的价值变得越来越重要。然而，个人的隐私可能会因为数据共享而受到损害。在本文中，我们研究了不同隐私数据发布问题，其目的是在隐私和数据效用之间取得平衡。具体而言，提出了两种基于区块链的数据发布协议。对于直方图发布，我们提出了一种利用区块链来验证查询结果中添加的拉普拉斯噪声的协议。对于匿名数据发布，我们提出了一种协议，该协议可以防止发布者和接收者在发布数据的效用上撒谎。由于区块链作为发布者和接收者之间的可靠中介，所提出的协议可以帮助实现公平和可审计的数据共享。
As more and more organizations deploy their sensing devices in the industrial Internet of Things network, it becomes increasingly important for the organizations to share data with others, so that the value of the data can be fully explored. However, individuals’ privacy may be compromised because of data sharing. In this article, we study the differentially private data publishing problem, which aims at balancing between privacy and data utility. Specifically, two blockchain-based data publishing protocols are proposed. For histogram publishing, we propose a protocol where the Laplace noise added in the query result is verified by the blockchain. For anonymized data publishing, we propose a protocol, which can prevent the publisher and the recipient from lying about the utility of the published data. With the blockchain acting as a reliable intermediary between the publisher and the recipient, the proposed protocols can help to realize fair and auditable data sharing.
