Abstract: In this presentation, we will present our recent progress in two areas: concurrency vulnerability detection and privacy-preserving signal processing. In the first area, we present an efficient approach to exploring thread interleavings in fuzz testing to detect concurrency bugs and vulnerabilities. By utilizing static analysis to locate potential concurrency vulnerabilities and arranging the execution in fuzz testing in the order that would trigger the vulnerabilities, we can significantly enhance the chance to trigger and thus detect the concurrency vulnerabilities. In the 2nd area, we present a joint design of encryption and detection to enable motion detection in the encryption domain with a given but adjustable granularity of motion trajectories for cloud surveillance applications. We will also present a novel method to enable JPEG decompression in the homomorphic encryption domain to support privacy preserving image processing in clouds.

Bio:
Bin Zhu: Dr. Bin B. Zhu is a lead researcher at Microsoft Research Asia (MSRA). Before he joined MSRA in December 2001, he worked for more than four years as a Lead Scientist at Cognicity, a company he co-founded with his Ph. D. advisor and a colleague in 1997. He has been working on data analytics and machine learning, Web/cloud and system security, authentication, privacy protection, content encryption and protection, data compression, and signal processing. He received his M.S. and Ph. D. in 1993 and 1998, respectively from Univ. of Minnesota and B.S. from Univ. of Science and Technology of China in 1986.

Changming Liu: He is a master student in computer science at Huazhong University of Science and Technology. He was an intern at Hong Kong Univ. in 2015, an intern at Microsoft Research Asia in 2017, and is now a 2nd-term intern at Microsoft Research Asia. He has published papers at ACM MM 2018, ACSAC 2018, and ICA3PP 2015.
