论文摘要
我们提出了一个名为Wibsontree的加密原始性，旨在通过允许用户在其个人属性上展示谓词，而无需揭示这些属性的值，以保护用户的隐私。我们认为有三种类型的代理商 - 购买者，卖方和公证人 - 在分散的隐私数据市场（DPDM）中进行互动，例如Wibson Marketplace。我们将Wibsontree协议介绍为有效的加密原始性，可在保留卖方的隐私时交换私人信息。使用我们的原始数据，数据销售商可以有效地证明他/她属于买方数据请求的目标受众，而无需透露任何其他信息。
We present a cryptographic primitive called WibsonTree designed to preserve users' privacy by allowing them to demonstrate predicates on their personal attributes, without revealing the values of those attributes. We suppose that there are three types of agents --buyers, sellers and notaries-- who interact in a decentralized privacy-preserving data marketplace (dPDM) such as the Wibson marketplace. We introduce the WibsonTree protocol as an efficient cryptographic primitive that enables the exchange of private information while preserving the seller's privacy. Using our primitive, a data seller can efficiently prove that he/she belongs to the target audience of a buyer's data request, without revealing any additional information.
