Hi guys,


Please attend this talk this Friday! It's a friend of mine. Thanks!




Title: Secure Access to Big Data with Confidentiality and Integrity

Speaker: Haibo Hu, Department of Computer Science, Hong Kong Baptist

Host: Kenny Q. Zhu

Time: 4 PM, Friday, July 3, 2015

Venue: SEIEE-03-414



With the prosperity of cloud computing and internet of things, huge 

amount of heterogeneous data have spawned new businesses which crave for 

integrating, querying, and analyzing big data. Among them, however, a 

lot of data are born private and sensitive, such as financial 

transactions, medical records, web/chat logs, and location traces. It is 

challenging to access them for analytical tasks while still preserving 

certain degree of confidentiality and integrity --- traditional 

cryptography may fail us on this scale of volume, velocity, and 

veracity. In this talk, I will discuss recent advances in secure access 

to these sensitive data from an information system's perspective. In 

particular, I will give several show cases on how cryptographic tools 

such as conditional oblivious transfer and homomorphic encryption are 

reinforced with database techniques such as indexing, pruning, and 

combinatorial optimization. These works can be put to practical use in 

financial engineering, health care, social network, and location-based 




Dr. Haibo Hu will be an assistant professor in the Department of 

Electronic and Information Engineering, Hong Kong Polytechnic University 

from September, 2015. He is currently a research assistant professor in 

the Department of Computer Science, Hong Kong Baptist University. He 

received his PhD degree from the Hong Kong University of Science and 

Technology in 2005. His research interests include data security and 

privacy, wireless data management, and location-based services. He has 

published over 50 research papers in refereed journals, international 

conferences, and book chapters. As PI, he has received over 4 million HK 

dollars external research grants. He served on organizing and program 

committee for many international conferences, and is the recipient of a 

number of awards, including ACM Best PhD Paper Award, Microsoft Imagine 

Cup, and GS1 Internet of Things Award.
