2、泛化的算法處理,敏感屬性進行隨機化算法處理,生成保護后的新數(shù)據(jù)表。通過與廣泛應用的MBF算法,GASCG算法進行實驗比較得出結(jié)論,該方法可以極大的提高隱私保護的效率降低個人信息的損失并且數(shù)據(jù)的效用性大大提高。關(guān)鍵詞:數(shù)據(jù)分類處理;k-匿名;泛化;隨機擾動;多敏感屬性中圖分類號:TM93文獻標識碼:B文章編號:1001–1390(2016)00–0000–00Theresearchandapplicationofinformationprivacyprotectionmethodforsmartgriduser-sidesinformationprivacyprotectionmethodG
