Privacy-Preserving Deep Learning Computation for Geo-Distributed Medical Big-Data Platforms

Abstract

This paper proposes a distributed deep learning framework for privacy-preserving medical data training. In order to avoid patients' data leakage in medical platforms, the hidden layers in the deep learning framework are separated and where the first layer is kept in platform and others layers are kept in a centralized server. Whereas keeping the original patients' data in local platforms maintain their privacy, utilizing the server for subsequent layers improves learning performance by using all data from each platform during training.Comment: 2019 IEEE/IFIP International Conference on Dependable Systems and Networks Supplementa
