Title: Evaluating the Security of Anonymized Big Graph/Structural Data

Speaker: Shouling Ji (Overseas Talents, Ph.D. in Georgia Tech )

Time: 10:00~11:30, September 7

Address: Room 3224 (Building No.3, Jingxiang Park)

Abstract:                                        

In this talk, we first summarize and discuss state-of-the-art graph anonymization techniques and de-anonymization attacks, and introduce the de-anonymization attacks presented by us. Subsequently, we study the theoretical foundation for the success of existing de-anonymization attacks along with large-scale evaluations on real-world graph data. Third, we propose, design, and implement SecGraph, a uniform and open-source Secure Graph data sharing/publishing system. Finally, we will discuss some future research directions.
