Enhancing Data Provenance and Model Transparency in Federated Learning Systems - A Database Approach

no code implementations3 Mar 2024 Michael Gu, Ramasoumya Naraparaju, Dongfang Zhao

Our findings show that our system can greatly enhance data transparency in various FL environments by storing chained cryptographic hashes and client model snapshots in our proposed design for data decoupled FL.
