Abstract

Frequent itemset mining is an essential problem in data mining and plays a key role in many data mining applications. However, users’ personal privacy will be leaked in the mining process. In recent years, application of local differential privacy protection models to mine frequent itemsets is a relatively reliable and secure protection method. Local differential privacy means that users first perturb the original data and then send these data to the aggregator, preventing the aggregator from revealing the user’s private information. We propose a novel framework that implements frequent itemset mining under local differential privacy and is applicable to user’s multi-attribute. The main technique has bitmap encoding for converting the user’s original data into a binary string. It also includes how to choose the best perturbation algorithm for varying user attributes, and uses the frequent pattern tree (FP-tree) algorithm to mine frequent itemsets. Finally, we incorporate the threshold random response (TRR) algorithm in the framework and compare it with the existing algorithms, and demonstrate that the TRR algorithm has higher accuracy for mining frequent itemsets.
