Seminar:  Crowdsourcing for Privacy and Security

Date:April 30, 2012 
Talk Title:Crowdsourcing for Privacy and Security
Speaker:Jason Hong
Time & Location:12:00pm - 1:00pm
CIC Building, Pittsburgh

Abstract

In privacy and security, there are a number of mechanisms that are beyond what can be fully automated and still require human judgements. In this talk, I present two projects my group has done examining how to incorporate crowdsourcing to improve privacy and security.

The first project looks at how to use crowdsourcing to improve anti-phishing blacklists. We demonstrate ways of improving the performance of the crowd, and show that our approach is much faster and more comprehensive in identifying phish.

The second project looks at how to use crowdsourcing to capture people's perceptions of privacy with respect to smartphone apps. We introduce the concept of privacy as expectations, and show how the crowd can be used to flag unusual behaviors of smartphone apps. We also show how the crowd's perceptions can be used to make better privacy summaries that emphasize unexpected behaviors that make people uncomfortable.
