摘要
利用数量积方法从垂直型分布数据中挖掘关联规则,并且保持其隐私性。给出了数量积算法,分析其安全性,同时还举例说明如何利用数量积算法进行垂直型分布式数据挖掘。
A privacy preserving association rule mining algorithm was introduced. This algorithm preserved privacy of individual values by computing scalar product. Meanwhile the algorithm of computing scalar product was given and the security was analyzed.
