Can security be improved by bringing personal data back to Japan? [Japan Times, Tokyo] Apr. 22—Following a data management incident in March, Line Corp. announced it would move sensitive user information from data centers in South Korea to Japan to ease concerns, especially from those in the public sector. But will transferring personal information data to Japan from overseas improve its safety? Not necessarily, critics say. Line’s data management drew flak last month after the firm acknowledged it allowed its Chinese software firm to access users’ personal information. The messaging app giant was also storing data including photos, videos and transactions of e-money Line Pay in data centers in South Korea.
