Going once, going twice... shared!

Sharing content on social networks can create privacy concerns: others could easily share your picture or other personal information without your permission. PhD candidate Onuralp Ulusoy designed a mechanism to tackle these issues. He used an auction-based approach, where users place bids to reach a collaborative outcome. He also designed a digital assistant to do the bidding for you. Ulusoy defended his thesis on 7 December. Imagine two similar pictures featuring you and three colleagues, taken during a business outing. As a group, you want to post one of the pictures online, but you disagree on which one it should be.
