A Study on How to Link, Intergrate, Utilize Multi-Source Data to Vitalize the Data Economy in the Health and Welfare Sectors(Ⅱ): With a Focus on the Linkage of Pseudonymized Data

Abstract

In line with the trends of open data, a growing amount of data is becoming accessible for users. However, such open data is primarily provided in unlinked, separate sets by different sources. In this study, our aim was to examine how data from multiple sources, when linked and integrated, can increase in utility and explore steps needed to be taken to overcome challenges in implementing data integration and linkage.
