Commissioner Ryu Invited to IMSI Workshop to Deliver a Keynote Speech -‘Hub and Spokes Model for Governmental Data’-   □ Commissioner Keunkwan Ryu delivered his keynote address at the Private AI Workshop organized online by the Institute for Mathematical and Statistical Innovation (IMSI)* on February 7 to February 12 (between 5 a.m. and 8:40 a.m. Korean time).      * IMSI: A research institute funded by the National Science Foundation, which aims to apply mathematics and statistics to societal and scientific problems and to foster innovation     ○ Under the theme of ‘Machine Learning on Encrypted Data’, the Workshop brought together many internationally recognized scholars and experts, including Vinod Vaikuntanathan of Massachusetts Institute of Technology, Kristin Lauter of Facebook AI Research, and Shai Halevi of Algorand Foundation.     ○ Participants at the workshop examined a range of solutions to technological challenges in applying innovative developments in machine learning and AI, with particular focus on privacy protection.   □ In his keynote speech titled ‘A Hub and Spokes Model for Governmental Statistics’, Commissioner Ryu presented the K-Statistics System currently under development by Statistics Korea (KOSTAT), in which public data are stored, linked, merged, and utilized in a safe manner. He also shared KOSTAT’s experience from a pilot project and suggested future direction for the K-Statistics System.     ○ Through the K-Statistics System, data are currently being linked within the Statistics Data Centers of KOSTAT. Commissioner Ryu said the System will be employing leading edge technologies, such as homomorphic encryption, differential privacy, and synthetic data, for further enhancing its data protection mechanism. In addition, efforts are being made to revise the Statistics Act which will ensure legal grounding for the utilization of administrative data.     ○ In addition, Commissioner Ryu introduced a pilot project which analyzed the survival patterns of SMEs using data linkage between KOSTAT’s statistical registers and the SMEs dataset of the Municipality of Gyeonggi-do. The pilot case attracted much attention from the participants of the workshop as it demonstrated logistic regression analysis, using linked data which remained encrypted throughout the process.   □ Commissioner Ryu concluded his remarks by sharing his prospects that the development of the K-Statistics System will boost data value for and cooperation among the government agencies, whereby it can further contribute to strengthening evidence-based policies. He added that technologies applied to the System will be shared with relevant international communities.   LINK : https://youtu.be/qlxahxBkOU8
