Big data and legal protection of personal data : Sharing personal data in science and technology

Abstract

Use of big data analytics creates opportunities to increase efficiency and improve predictions. However, a large amount of personal data may cause problems in preserving privacy. "Open science", which often refers to an approach to research based on greater access to public research data, may expand problems when the data shared by different research organizations contains personal data. This article states what researchers and engineers should care, on sharing of personal data. We also outline the revision of "Act on the Protection of Personal Information".
