Marshini Chetty, an assistant professor in the College of Information Studies and a member of the Human-Computer Interaction Lab, was awarded an NSF grant for the project “EPICA: Empowering People to Overcome Information Controls and Attacks.”
The project, which she is collaborating on with four other researchers from the University of Michigan and the Georgia Institute of Technology, studies the security of representative personalized services, such as search engines, news aggregators and online targeted advertising, and identifies vulnerabilities in service components that can be exploited by pollution attacks to deliver content intended by attackers. Additionally, the project develops defense-in-depth countermeasures against pollution attacks.
