Abstract:
As we move further into the big data era, people are motivated in numerous ways to proactively generate, share and exchange diverse digital contents online every day. While the increasing amount of information greatly facilitates people’s decision makings, it also brings great challenges. For example, driven by the huge profits behind the big data economy, malicious attacks are emerging rapidly to mislead normal users’ decision-making process by providing carefully crafted false information.

In addition, retrieving tremendous amount of user private information has become a popular attack target. This talk will discuss the security, trust and privacy issues in online social networks, the trend and challenges. In particular, three sample projects will be discussed, including (1) Efficiently Promoting Product Online Outcome: An Iterative Rating Attack Utilizing Product and Market Property; (2) Retrieving Hidden Friends: A Collusion Privacy Attack Against Online Friend Search Engine; and (3) AMICA: Alleviating Misinformation for Chinese American.
