The index storage models of the hybrid index mechanism have three models: tree model, hash index model and invertedfile model.
混纯索引机造采取的索引亡储模型从要无树、哈希和反排文件三类方式。

Based on data-distort method, we propose privacy preserving association rules mining algorithm IFB-PPARM using efficient data structure namely invertedfile.
基于数据变换法,提出使用高效数据结构即倒排文件的隐私保护关联规则挖掘算法ifb - PPARM。

The algorithm only need scan the transaction database once, and all the transaction operations are carried out on the invertedfile mapped from transaction database.
