Data Privacy

Organizations collect vast amounts of information on individuals. At the same time, they have access to increasing levels of computational power. Although this conjunction of information and power provides great benefits to society, it also threatens individuals’ privacy. Thus, data privacy and protecting individuals’ anonymity have become mainstream for research. Recently, we have carried out research including the following.

  • Differential privacy
  • Privacy-preserving sharing of health data
  • Privacy-preserving maching learning
  • Federated learning
