Shadow Profiles on Social Networks
Emre Sarigol joins me this week to
discuss his paper Online Privacy as a Collective Phenomenon.
This paper studies data collected from social networks and how the sharing behaviors of individuals can unintentionally reveal private information about other people, including those that have not even joined the social network!
For the specific test discussed, the researchers were able to accurately predict the sexual orientation of individuals, even when this information was withheld during the training of their algorithm.
