Privacy-Preserving Data Sharing on Multi-Layer Blockchain: Case Study on Healthcare

EasyChair Preprint 1291

Abstract

This thesis designs a data exchange system architecture and applies it to healthcare cases, and will solve the following two problems. First, children forgets whether the type vaccines that has been vaccinated or not. Then, he/she has to vaccinate again in case. Second, we implement the medical record exchange between hospitals. The same concept can also be applied to the following situations. If someone sees a doctor in different hospitals, the medicines from different hospital may have drug interactions, which may cause side effects after taking them at the same time. Doctors can avoid this situation with the information through the blockchain. Recently, the applications of the medical blockchain are mostly implemented by Ethereum. This thesis, unlike other Ethereum applications, also proposed a new multi-layer blockchain architecture and replaced the consensus mechanism in order to speed up and make the system more reasonable in use.
