报告题目：FinTech, Data Analysis, and Privacy Preservation        

报告摘要:  Many data aresensitive in areas such as finance, economics, political science, and lifescience. How to protect individual privacy when collecting and analyzing datahas become even more significant and has raised growing public concerns in theage of big data because a huge amount of personal data are being generated andused almost freely every day. We propose an ER (encryption and recovery)algorithm that allows a central administration to do statistical inferencebased on the encrypted data, while still preserving each party's privacy evenfor a colluding majority in the presence of cyber attack. Theoretically, weessentially establish a general framework for privacy-preserving statisticalinference, which can be viewed as the sensitive data based counterpart oftraditional statistical inference assuming availability of the data. Wedemonstrate the applications of our algorithm to linear regression, logisticregression, maximum likelihood estimation, estimation of empiricaldistributions, and estimation of quantiles. Moreover, our algorithm can help toaddress another practically significant issue -- privacy preservation fordistributed statistical inference when data are allocated to different partieswho are unwilling to share their own data with others. Our algorithm is apromising “technology” that can be applied to overcomethe difficulties of data analysis with privacy preservation not only infinancial industry but also in other areas concerning people's privacy rightsin the era of big data.
