论文摘要
本文介绍了基于分布式分类帐技术（DLTS）和分散文件存储（DFS）系统的体系结构，以支持个人信息管理系统（PIMS）的使用。 DLT和DFS用于管理配备具有感应功能的设备的移动用户感知的数据。 DLT保证了对DFS中存储的对个人数据的参考的不可变，可追溯性和可验证性。实际上，在DLT中包含数据摘要使得获得不可更改的参考和防篡改日志，同时仍符合个人数据法规，即GDPR。我们提供了有关使用DFS的可行性的实验评估。已经研究了三种不同的方案：i）专有IPFS方法与数据生产者进行专用的节点接口，ii）公共IPFS服务和III）SIA SKYNET。结果表明，通过对系统基础架构的正确配置，可以构建分散的个人数据存储（PDS）可行。
This paper presents an architecture, based on Distributed Ledger Technologies (DLTs) and Decentralized File Storage (DFS) systems, to support the use of Personal Information Management Systems (PIMS). DLT and DFS are used to manage data sensed by mobile users equipped with devices with sensing capability. DLTs guarantee the immutability, traceability and verifiability of references to personal data, that are stored in DFS. In fact, the inclusion of data digests in the DLT makes it possible to obtain an unalterable reference and a tamper-proof log, while remaining compliant with the regulations on personal data, i.e. GDPR. We provide an experimental evaluation on the feasibility of the use of DFS. Three different scenarios have been studied: i) a proprietary IPFS approach with a dedicated node interfacing with the data producers, ii) a public IPFS service and iii) Sia Skynet. Results show that through proper configuration of the system infrastructure, it is viable to build a decentralized Personal Data Storage (PDS).
