I received the Ph.D. degree in Computer Science at Illinois Tech. under the supervision of Professor Xiang-Yang Li and Professor Peng-Jun Wan in 2017, and I received the B.E. degree in Computer Software in Tsinghua University under the supervision of Professor Zhiguo Wan in 2011.
Various encryption and secure multi-party computation are able to preserve a nearly-perfect confidentiality of almost all computation nowadays, however privacy can be breached even though the computation/communication are perfectly secured. Differential privacy addresses such concerns, but we have to sacrifice the nearly-perfect accuracy of computation/query with its probabilistic privacy protection. Can human being have nearly-perfect guarantee (i.e., as strong as that provided by encryption/MPC) for privacy without the loss of utility? That is the ultimate question I keep asking myself while doing research.
