This is to let you know that I have updated the SPMF
framework to add an association rule hiding algorithm
The goal of this algorithm is to hide some sensitive association rules
that appear in a database.
For example, consider that the rule 5 -->2 appears in a database with minsup = 50% and minconf = 50%.
We can apply the FHSAR algorithm. It takes as input (1) a database, (2) the sensitive association rules that we want to hide (e.g. 5 --> 2), (3) minsup and minconf and (4) the file path to save the transformed database.
The FHSAR algorithm proceeds by recursively removing items from transactions until all sensitive association rules cannot be found with the minsup and minconf thresholds.
It then outputs the transformed database to a file.
