英文摘要： Online consumption has show its huge economic and social effects, while the lack of privacy protection for online consumers has become an important problem that draws great attention of the society. This project studies the theory and method for protecting the private information of online consumers, especially for the personal information. The project focus on the scenarios with malicious parties and delivery companies in the transactions, studying the privacy model for online consumers, privacy-preserving transaction scheme, and privacy-preserving reputation scheme. Our objectives are the following. 1) Studying the quantifiable general privacy model for online consumption to establish the general privacy model and utility model, providing theory foundation for the analysis and design of privacy-preserving solution for online consumption. 2) Studying the privacy-preserving transaction scheme for online consumption which support anonymous physical object delivery, balancing between privacy protection and data utility, and designing method for physical object delivery with strong privacy and high data utility. 3) Studying the privacy-preserving reputation mechanism for online consumption and designing privacy-preserving reputation mechanisms which can avoid malicious extortion.
