There are two major challenges in artificial intelligence field today. One is that in most industries, data exists in the form of isolated islands. The other is the increasing demand for AI to be aware of user privacy and data security. We give an overview of these challenges and survey recent works on secure federated learning to meet them. We will describe the federated learning framework by considering horizontal federated learning, vertical federated learning and federated transfer learning. We provide definitions, architectures and applications for the federated learning framework. We also survey related works in AI security, privacy and confidentiality. We will show some typical application scenarios of the technology. Finally we describe a development roadmap for federated and transfer learning.
