i-Blockchain: A Blockchain-Empowered Individual-Centric Framework for Privacy-Preserved Use of Personal Health Data
Abstract
With the rapid development of information and communication technology, a vast amount of personal health data is generated, stored, and utilized in healthcare related services. However, there are many issues remained to be solved, such as data interoperability, security, and privacy concerns. On the other hand, blockchain, a decentralized peer-to-peer digital ledger, has attracted a lot of attention in recent years as a promising technology to protect privacy of personal data. By adopting blockchain, individuals can take advantage of personal health data for better healthcare. In this paper, after briefly summarizing the major features of blockchain, we describe blockchain-empowered solutions for utilization of personal health data in healthcare and discuss issues and challenges. We further propose i-Blockchain, an individual-centric framework for use of personal health data based on an extension of permissioned blockchain, present the basic architecture and protocols, and show several application scenarios.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
