SPMF update: new algorithm for hiding association rules (FHSAR)
Date: October 29, 2011 04:21AM

Hello,

This is to let you know that I have updated the SPMF framework to add an association rule hiding algorithm named FHSAR.

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.

Philippe

Hello!
Now, I'm using your FHSAR algorithm code to demo my project and I'm wondering about a problem that is in the paper of Weng, C. C., Chen, S. T., & Lo, H. C. (2008, November) 'A Novel Algorithm for Completely Hiding Sensitive Association Rules', algorithm has checking step 'Checking_and_Removing Item()' to avoided hidden failure. But I don't find it in your code. Can you help me explain it? And if so I really want you to help me code this part.
Thank you very much!

Hi,
Thanks for using SPMF!

I checked the paper just now, and I think that is not explained clearly what Checking_and_removing_item() is supposed to do. Thus, it would be hard to implement this function. If you want to implement it, I think that you should contact the authors of the paper to ask more details about what this function is supposed to do. But with the current paper, I think we don't have enough details to implement it.

Best regards,
