The Role of Noise and Epsilon in Differential Privacy
What is the Significance of Epsilon and Delta in Differential Privacy?

In Differential Privacy, the parameters epsilon (ε) and delta (Δ) are critical in defining the level of privacy. Epsilon represents the measure of privacy loss, with smaller values indicating stronger privacy. It controls the degree of randomness added to the data, ensuring that the presence or absence of any individual's data does not significantly alter the output. Delta, typically a small value near zero, allows for a slight probability of deviation from this guarantee. Together, these parameters provide a mathematical framework for quantifying privacy, enabling the fine-tuning of privacy levels to balance data utility and privacy concerns. The choice of ε and Δ values is a critical decision in implementing Differential Privacy, impacting the effectiveness of privacy protection and the utility of the output.
