Enhancing Local Differential Privacy Accuracy by Exploiting Inherent Uncertainty
Summary: Introduces inherent uncertainty to quantify correlation-induced protection from non-sensitive attributes, then uses it to calibrate LDP noise more tightly under the same sensitive-attribute \u03b5-LDP guarantee. Also proposes a dual-phase mechanism for mixed attributes, improving utility without weakening inference protection. (summarized by gpt-5-mini on Apr 11 2026)
