摘要：In a lot of real-world machine learning applications, data are provided by multiple providers and each maintains private records of different feature sets about common entities. The privacy-preserving federated learning for vertically partitioned data has shown promising results as the solution of the emerging multi-party joint modeling application, in which the data holders collaborate throughout the learning process rather than relying on a trusted third party to hold data. This talk will discuss the challenge of data privacy of vertical federated learning (VFL) compared to the horizontal one. Instead of using traditional secure techniques (such as Encryption, secure multi-party computation, and differential privacy), we utilize the idea of isolating local data and model as much as possible to achieve lightweight and lossless data privacy. We will practice this idea to achieve fast and secure VFLs.
