Our algorithm can be used for privacy protection of periodic itemsets and is based on a data perturbation strategy.

Our algorithm is located in the PPPUM/src/main/PPPUM and PPPUM/src/test folders.

The PHM code here is derived from reference [1], and the experimental comparison algorithm we named as folder LiuXuan, with the code sourced from [2].
