论文摘要
在本文中，我们介绍了一个基于新兴的自我主张身份标准，区块链和基于属性的加密的数据胶囊模型，这是一个独立且自我强制的数据容器。数据胶囊允许对个人数据进行透明，尊重隐私和安全的交换，从而在半信任的环境中实现渐进信任计划。每个数据胶囊都与自己的访问策略结构和可验证的数据捆绑在一起，从而大大减少了用户，服务提供商和数据保管人所需的交互数量。此外，通过依靠区块链和基于属性的加密的分散性质，我们提出的模型可确保服务提供商发布的访问策略是公共，透明且严格遵循的。
In this paper, we introduce a data capsule model, a self-contained and self-enforcing data container based on emerging self-sovereign identity standards, blockchain, and attribute-based encryption. A data capsule allows for a transparent, privacy-respecting, and secure exchange of personal data, enabling a progressive trust scheme in a semi-trusted environment. Each data capsule is bundled with its own access policy structure and verifiable data, drastically reducing the number of interactions needed among the user, the service providers, and data custodians. Moreover, by relying on the decentralized nature of blockchain and attribute-based encryption our proposed model ensures the access policies published by service providers are public, transparent, and strictly followed.
