Background:

Data anonymization is crucial for privacy and data reuse.
Anonymizing complex, high-dimensional datasets while preserving data quality is challenging.
Existing tools may struggle with high-dimensional biomedical data.

Purpose of the Study:

To enhance the ARX software for improved handling of high-dimensional biomedical datasets.
To develop novel algorithms for more efficient data anonymization.
To improve the usability and performance of ARX for complex data.

Main Methods:

Implemented two novel search algorithms: a greedy top-down approach and a genetic algorithm-based approach.
Extended the ARX software's graphical user interface (GUI).
Evaluated algorithms using diverse datasets, transformation methods, and privacy models.

Main Results:

The novel algorithms generally outperformed the existing bottom-up search in ARX.
Enhanced ARX demonstrates improved processing performance for high-dimensional data.
The updated GUI offers greater usability when working with large datasets.

Conclusions:

The enhancements significantly improve ARX's capability to handle high-dimensional data.
Increased processing performance and usability facilitate secure data sharing.
ARX is better equipped to support privacy-preserving analysis of complex biomedical data.
