通过研究数据挖掘隐私保护，借助乘法扰动算法，探索提出了一种全新的算法---已知信息独立分量分析(Known Knowledge Independent Component Analysis)，这种算法可以从经过旋转扰动或随机投影变换的扰动数据得到近似值或者原始数据；紧接着，得出全新的乘法扰动隐私保护算法---局部旋转扰动方法(Partial Rotation Perturbation)，此法能够有效抵御KK- ICA的攻击并且安全性更高。
通過研究數據挖掘隱私保護，藉助乘法擾動算法，探索提齣瞭一種全新的算法---已知信息獨立分量分析(Known Knowledge Independent Component Analysis)，這種算法可以從經過鏇轉擾動或隨機投影變換的擾動數據得到近似值或者原始數據；緊接著，得齣全新的乘法擾動隱私保護算法---跼部鏇轉擾動方法(Partial Rotation Perturbation)，此法能夠有效牴禦KK- ICA的攻擊併且安全性更高。

mining data privacy protection through research, with the multiplication perturbation algorithm is proposed to explore a new algorithm - known information independent component analysis (Known Knowledge Independent Component Analysis), this algorithm can be rotated through the disturbance or ran-dom projection transformation from approximations or perturbation data obtained raw data; Then, draw a new algorithm for multiplication disturbance Privacy -local rotation perturbation method (Partial Rotation Perturbation), this method can effectively resist the KK- ICA attack and more secure.
