The Insecurity of Sharing MY Life on the Web: The Butterfly Effect of Images and Videos in Social Networks
Raphaël Troncy · Graduate School and Research Center in Digital Science (EURECOM) · 2010
People are more and more interconnected online and active in publishing and sharing their thoughts, feelings, activity, and recorded experiences in media items within their social networks. This new massive amount of data is however usually locked into proprietary platforms with evolving privacy policies. We are interested in indexing and analyzing photos and videos shared on the Web and in studying their diffusion as well as the correlations we can deduce based on subject matters depicted. We are advocating the use of semantic web and forensic imaging technologies for providing new tools to protect users privacy. We use linked data technologies to represent and expose all metadata gathered during these analysis processes. We are actively working in the W3C Media Fragments Working Group for standardizing how to express media fragments in a URI. Finally, we are developing environments that enable contextualized exploration of multimedia content within social networks revealing unexpected connections between objects and people.
