Abstract
The increasing need to protect individual privacy in data releases has
led to significant advancements in privacy-preserving technologies.
Differential Privacy (DP) offers robust privacy guarantees but often at
the expense of data utility. On the other hand, data pooling, while
improving utility, lacks formal privacy assurances. Our study introduces
a novel hybrid method, termed PoolDiv, which combines differential
privacy with data pooling to enhance both privacy guarantees and data
utility. Through extensive simulations and real data analysis, we assess
the performance of synthetic datasets generated via traditional DP
methods, data pooling, and our proposed PoolDiv method, demonstrating
the advantages of our hybrid approach in maintaining data utility while
ensuring privacy.
