• Abstract summary: Federated learning (FL) emerges as a functional solution to build high-performance models shared among multiple parties. We present DID-eFed, where FL is facilitated by decentralized identities (DID) and a smart contract. We describe particularly the scenario where our DID-eFed enables the FL among hospitals and research institutions.

• Abstract: We have entered the era of big data, and it is considered to be the "fuel" for the flourishing of artificial intelligence applications. The enactment of the EU General Data Protection Regulation (GDPR) raises concerns about individuals' privacy in big data. Federated learning (FL) emerges as a functional solution that can help build high-performance models shared among multiple parties while still complying with user privacy and data confidentiality requirements. Although FL has been intensively studied and used in real applications, there is still limited research related to its prospects and applications as a FLaaS (Federated Learning as a Service) to interested 3rd parties. In this paper, we present a FLaaS system: DID-eFed, where FL is facilitated by decentralized identities (DID) and a smart contract. DID enables a more flexible and credible decentralized access management in our system, while the smart contract offers a frictionless and less error-prone process. We describe particularly the scenario where our DID-eFed enables the FLaaS among hospitals and research institutions.

  In recent years, federated learning has become a popular paradigm for training distributed, large-scale, and privacy-preserving machine learning (ML) systems. In a typical FL system, the central server acts only as an orchestrator; it iteratively gathers and aggregates all the local models trained by each client on its private data until convergence. One of the most critical challenges is to overcome the centralized orchestration of the classical FL client-server architecture. Decentralized FL solutions have emerged where all FL clients cooperate and communicate without a central server.

  Federated Learning (FL) is a machine learning paradigm where many local nodes collaboratively train a central model while keeping the training data decentralized. We propose a privacy-preserving FL framework leveraging unlabeled public data for one-way offline knowledge distillation. Our technique uses decentralized and heterogeneous local data like existing FL approaches, but more importantly, it significantly reduces the risk of privacy leakage.
