Webb11 apr. 2024 · This work introduces variation-ratio reduction as a unified framework for privacy amplification analyses in the shuffle model and shows that the framework yields tighter bounds for both single-message and multi-message encoders and results in stricter privacy accounting for common sampling-based local randomizers. In decentralized … WebbThis work studies differential privacy in the context of the recently proposed shuffle model. Unlike in the local model, where the server collecting privatized data from users can track back an input to a specific user, in the shuffle model users submit their privatized inputs to a server anonymously. This setup yields a trust model which sits in between the …
