In differential privacy, the smaller the privacy budget ε, the stronger the privacy protection, but the larger the noise introduced, causing the estimation error to rise.

UnverifiedDifferential privacy noise reduces data utility, federated learning has communication overhead and model convergence challenges, and synthetic data may introduce distributional bias.80% similarUnverifiedAcross multiple image datasets, these lower bounds establish non-trivial, unavoidable expected reconstruction errors within the privacy budget range recommended by the industry.77% similarUnverifiedOn sentiment generation and safety alignment benchmarks, the framework shows significant advantages over dense baselines, with the sparse method achieving lower estimation error under the same privacy budget.73% similarUnverifiedPrompt desensitization faces a utility-privacy trade-off: the more thorough the desensitization, the less context available to the model, and the more pronounced the decline in answer quality; for tasks that highly depend on complete context, such as code completion, legal document analysis, and medical question answering, the room for desensitization is extremely limited.72% similarUnverifiedExperiments show that even when common defensive measures (such as regularization, differential privacy noise, output perturbation, etc.) are applied, singleton records remain highly vulnerable.70% similar
