论文摘要
Soteria是一种用户权利管理系统，旨在以透明且可证明的方式保护用户数据隐私，以符合GDPR和CCPA等法规。 Soteria代表用户数据权作为正式的可执行共享协议，可以自动转化为人类可读形式，并在查询数据时执行。为了支持撤销并证明合规性，数据访问和共享协议的不可磨灭的，经过审核的踪迹存储在两层分布式分类帐中。主链确保分区的耐受性和可用性（PA）属性，而侧链确保一致性和可用性（CA），从而提供了CAP的三个属性（一致性，可用性和分区公差）定理。除了描绘索特里亚的两层体系结构外，本文还评估了代表性共识协议并报告绩效统计。
Soteria is a user right management system designed to safeguard user-data privacy in a transparent and provable manner in compliance to regulations such as GDPR and CCPA. Soteria represents user data rights as formal executable sharing agreements, which can automatically be translated into a human readable form and enforced as data are queried. To support revocation and to prove compliance, an indelible, audited trail of the hash of data access and sharing agreements are stored on a two-layer distributed ledger. The main chain ensures partition tolerance and availability (PA) properties while side chains ensure consistency and availability (CA), thus providing the three properties of the CAP (consistency, availability, and partition tolerance) theorem. Besides depicting the two-layer architecture of Soteria, this paper evaluates representative consensus protocols and reports performance statistics.
