Differential privacy has been adopted in various real-world applications, reflecting its growing importance in the field of data privacy. Tech companies like Google and Apple use differential privacy to collect usage data while preserving user privacy. The US Census Bureau employs differential privacy mechanisms to protect individual data in public census releases. Additionally, differential privacy is being increasingly integrated into data analytics tools and platforms, enabling organisations to analyse sensitive datasets without compromising individual privacy. These applications demonstrate differential privacy's versatility and effectiveness in addressing modern privacy concerns.
