当今时代,随着大数据技术的飞速发展和数据量的持续增加,大量数据不断被不同的公司或者机构收集,把来自不同公司或机构的数据聚合起来并发布,有助于更好地提供服务、支持决策。然而他们各自的数据中可能包含敏感程度不同的隐私信息,所以在聚合发布各方数据时需要满足个性化隐私保护要求。针对个性化隐私保护的多方数据聚合发布问题,该文提出满足个性化差分隐私的多方垂直划分数据合成机制(PDP-MVDS)。该机制通过生成低维边缘分布实现对高维数据的降维,用低维边缘分布更新随机初始的数据集,最终发布和各方的真实聚合数据集分布近似的合成数据集;同时通过划分隐私预算实现个性化差分隐私保护,利用安全点积协议和门限Paillier加密保证各方数据在聚合过程中的隐私性,利用分布式拉普拉斯机制有效保护了多方聚合边缘分布的隐私。该文通过严格的理论分析证明了PDP-MVDS能够确保每个参与方数据和发布数据集的安全。最后,在公开数据集上进行了实验评估,实验结果表明PDP-MVDS机制能够以低开销生成高效用的多方合成数据集。

In order to optimize the ultrasonic extraction technique for the total flavonoid of leaf yellows plus, the contents of 21 leaf yellows plus total flavonoid from four regions in Heilongjiang Province were comparatively analyzed. The ultrasonic extraction technology was optimized by Box-Behnken response surface method, and the total flavonoid content of 21 kinds of Acanthopanax senticosus(Rupr. et Maxim.) Harms from different producing areas were analyzed by cluster analysis. The optimal process conditions were determined as ultrasonic time 30 min, solid-liquid ratio 1 : 12 and ultrasonic power 250 W, and the average yield of the total flavonoid was 1.453 mg·g^ (-1). By optimizing the ultrasonic-assisted extraction method, the total flavonoid content from different producing areas was compared in the experiment, which provided certain data support for the optimization of the extraction process in the future and laid a certain theoretical foundation for the quality analysis of Chinese medicinal materials.
