[Sejong=Asia Economy Reporter Moon Chaeseok] The Statistics Development Institute (SRI) of Statistics Korea announced on the 3rd that it will publish a book summarizing research results on privacy protection methods used in SGIS data, a statistical service that informs whether commercial facilities such as cafes and restaurants can be reached by car within a certain time.

In the third issue of the "Data Research Brief" to be published by SRI on the same day, research results on the disclosure risk and confidentiality protection methods of frequency tables provided by the Statistical Geographic Information Service (SGIS), as well as pilot services for expanded public geographic information data, are included. The core of the research is applying privacy protection methods to the frequency tables provided by SGIS. It is also the first innovative study to apply confidentiality protection algorithms to the 2018 Population and Housing Census data to examine data consistency and information loss.

Statistics Korea is preparing a public service that provides data with a password system applied to minimize information loss and enhance security, reflecting the research results. Especially, with the passage of the three major domestic data laws, data linkage is being activated in the industrial field, making the importance of privacy protection increasingly significant. A representative from the SRI Data Information Protection Center said, "We are dedicated to developing practical information protection techniques that prevent the risk of individual information exposure and maximize data sharing."
