效用优化本地差分隐私模型能够在保证隐私的前提下提高估计结果准确度. 但现有的效用优化本地差分隐私协议存在着数据效用低或通信代价大的问题. 本文针对现有效用优化本地差分隐私协议难以兼顾低通信代价和高数据效用的不足, 基于 OLH (optimized local hashing) 协议提出了符合效用优化本地差分隐私模型的 uOLH (utility-optimized OLH) 协议. 该协议在原始数据定义域很大时, 同时具有低通信代价和高数据效用的特点, 兼顾 uRR (utility-optimized randomized response) 和 uRAP (utilityoptimized randomized aggregatable privacy-preserving ordin...
