## Abstract (arXiv)

Federated learning is an emerging privacy-preserving distributed machine learning that enables multiple parties to collaboratively learn a shared model while keeping each party's data private. However, federated learning faces two main problems: semi-honest server privacy inference attacks and malicious client-side model theft. To address privacy inference attacks, parameter-based encrypted federated learning secure aggregation can be used. To address model theft, a watermark-based intellectual property protection scheme can verify model ownership. Although watermark-based intellectual property protection schemes can help verify model ownership, they are not sufficient to address the issue of continuous model theft by uncaught malicious clients in federated learning. Existing IP protection schemes that have the ability to track traitors are also not compatible with federated learning security aggregation. Thus, in this paper, we propose a Federated Client-side Intellectual Property Protection (FedCIP), which is compatible with federated learning security aggregation and has the ability to track traitors. To the best of our knowledge, this is the first IP protection scheme in federated learning that is compatible with secure aggregation and tracking capabilities.
