DESCRIPTION:Ph.D. Committee:聽 Drs. Derek Doran (advisor)\, Michael Raymer\,
  Krishnaprasad Thirunarayan\, and Amir Zadeh (Department of Information Sy
 stems & Supply Chain Management)ABSTRACT:Tor is the most popular dark netw
 ork in the world. Its noble uses\, including as a platform for free speech
  and information dissemination under the guise of true anonymity\, make it
  an important socio-technical system in society. Although activities in so
 cio-technical systems are driven by both structure and information\, past 
 studies on evaluating Tor investigate its structure or information exclusi
 vely and narrowly\, which inherently limits our understanding of Tor. This
  dissertation bridges this gap by contributing insights into the logical s
 tructure of Tor\, the types of information the service hosts\, and the int
 erplay between structure and content. These insights arise from three stud
 ies:First\, we perform a comprehensive crawl of the Tor dark Web and\, thr
 ough topic and network analysis\, characterize the types of information an
 d services hosted across a broad swath of Tor domains and their hyperlink 
 relational structure. We recover nine domain types defined by the informat
 ion they host and\, among other findings\, unveil how marketplaces of ille
 gal drugs and services do emerge as the dominant type of Tor domain. We al
 so present measurements that indicate how some types of domains intentiona
 lly silo themselves from the rest of Tor. Second\, we study the potential 
 for thought-to-be isolated information on the dark Web to be leaked into t
 he public surface Web by providing a broad evaluation on the network of re
 ferencing from Tor to surface Web. Results recover the dark-to-surface net
 work as a single massive connected component where over 90% of Tor hidden 
 services have at least one link to the surface world despite their interes
 t in being isolated from surface Web tracking. To further investigate the 
 interplay between the structure and information of Tor\, we propose to stu
 dy the structural identity of Tor domains as a potential future extension 
 of this study.
