Privacy-preserving data analysis is gaining significant attention in the current era of big data, driven by growing public concerns about data privacy. This focus is particularly crucial for financial data analysis, given the heightened importance of digital finance and FinTech as well as the sensitive nature of financial data. We develop a series of privacy-preserving algorithms to address various critical aspects of data analysis, including data collection, statistical inference, and resampling. The privacy preservations of these algorithms are justified theoretically in the sense of carefully formulated definitions. Furthermore, we demonstrate the applications of these algorithms to machine learning.
