Background:

Data sharing is prevalent in healthcare, necessitating methods to protect sensitive information.
Local Distortion Hiding (LDH) is a privacy-preserving technique for data sharing.
Previous evaluations of LDH assumed attackers used the J48 (C4.5) classification algorithm.

Purpose of the Study:

To extend the evaluation of Local Distortion Hiding (LDH) against a different classification algorithm.
To assess the effectiveness of LDH when faced with the CART algorithm.
To present a case study of a medical dataset processed using LDH and attacked with CART.

Main Methods:

Application of the Local Distortion Hiding (LDH) algorithm to a medical dataset.
Simulating an attack on the processed dataset using the CART classification algorithm.
Analyzing the effectiveness of LDH in preventing pattern discovery by the CART algorithm.

Main Results:

The study demonstrates that LDH can successfully conceal sensitive patterns in a medical dataset.
The CART algorithm attack was evaluated against the LDH-processed data.
LDH proved effective in protecting data against the CART attack, extending previous findings.

Conclusions:

Local Distortion Hiding (LDH) offers robust protection for sensitive medical data during sharing.
The security of LDH extends beyond the J48 (C4.5) algorithm to include the CART algorithm.
This research validates LDH as a viable method for secure medical data sharing.
