Abstract

Key words of the Fourth Industrial Revolution Era are Big Data, Artificial Intelligence, Block Chain and so on. The key point of the Fourth Industrial Revolution is to achieve technical innovation through use of digital information. At this time, as a way to secure the characteristics of digital information, the block chain technology has been discussed and is attracting attention. As the world enters modern times, the use of information system by medical institutions is increasing. Especially recently, as access to personal medical information gets easier due to the development of Information Technology such as U-health and Smart Health, the infringement risk of personal medical information is on the rise. In order to solve this problem and strengthen the medical information system, the research to introduce block chain technology into medical information system has been conducted. This study involved experts in the large general hospitals. To introduce block chain technology into medical information system, 5 characteristics of block chain (security, availability, reliability, diversity and economic feasibility) have been set up as the variables of this research and the model of this research has been designed theoretically based on AHP analysis method to analyze priority of 4 block chain types (disclosure & no approval, confidentiality & no approval, disclosure & approval, confidentiality & approval.) The study reaches the conclusions that the most important characteristic among the five characteristics of the block chain is Security and when the block-chain technology is introduced into the medical information system. "Confidential and Approval" type was ranked as the first. In addition, this study suggests the direction in order for block-chain to be applied and be spread in the medical field and what the most appropriate study model based on the results of empirical analysis would be and further suggests implications from a practical and academic viewpoint.
