ABSTRACT
Blockchain technology is a distributed database, which is a Ledger technology that records changes, for example, adding information, revising, and deleting in the unit of blocks and share. Here, the ledger means a list of transactions, but Blockchain technology can be applied to all data if it is interpreted as shared information. This paper proposed a method of applying Blockchain technology in the medical field and using it in PHR applications. That is, an architecture is proposed for a gateway application of healthcare data for easy and safe control and sharing of PHR data. If Blockchain technology is applied to PHR service in this way, it may affect a distributed database that provides saving and backup/restore functions for medical information by transmitting/saving medical information to each existing base medical institution. Through this, the Blockchain Server for each participating base of the Blockchain Network can serve as an Interface for utilizing medical information along with medical information saving.
