Abstract
Privacy-Preserve Utility Mining is becoming a topic of interest to many researchers. The goal is to protect the sensitive-high utility itemsets in the transaction databases from being exploited by data mining techniques. This paper studies methods to hide sensitive high utility itemsets in transaction databases. There are some effective methods to deal with this problem, but these methods still cause undesirable side effects, such as: being missing hidden itemsets with non-sensitive high utility itemsets, the difference between the original database and the modified database, etc. This paper proposed an improved algorithm for hiding sensitive high utility itemsets, called IEHSHUI, focus on choosing the order to hide sensitive itemsets and selecting items to modify with minimal side effects. Experimental results show that the IEHSHUI proposed algorithm is more efficient than existing algorithms in terms of execution time.
