Differential privacy finds industry-specific applications in sectors like healthcare, finance, and online services. In healthcare, it can protect patient data while allowing for research on aggregate health trends. In finance, differential privacy can safeguard customer data in fraud detection systems or market analysis tools. For online services and social media platforms, it helps in analysing user behaviour without compromising individual user privacy. Each industry presents unique challenges in implementing differential privacy, particularly in terms of the sensitivity of the data and the specific use cases.
