Our main objective is to develop a novel metric and scenario that leverages information about future data usage to optimize budget distribution. Effective budget distribution is pivotal in enhancing data utility without compromising privacy, a significant challenge in the DP field. We identify and exploit a gap related to the interactions between DP queries to improve data utility. Our metric is formally defined, and we apply it through a hypothetical scenario using synthetic data. The results indicate a substantial improvement in data utility while maintaining privacy. This study offers a valuable contribution to the DP field and opens avenues for future research and practical applications in real-world scenarios", publisher = {Pontif?cia Universidade Cat?lica do Rio Grande do Sul}, scholl = {Programa de P?s-Gradua??o em Ci?ncia da Computa??o}, note = {Escola Polit?cnica} }
