"Internet Privacy: Towards More Transparency"

Internet privacy has become a hot topic recently with the radical growth of Online Social Networks (OSN) and attendant publicity about various leakages. For the last several years we have been examining aggregation of user's information by a steadily decreasing number of entities as unrelated Web sites are browsed. More recently we have found leakage of user's data to the same aggregating entities as a result of interaction with OSNs. I will present results from several studies on leakage of personally identifiable information (PII) via Online Social Networks (both traditional and mobile OSNs) and popular non-OSN sites. Linkage of information gleaned from different sources presents a challenging problem that has captured the attention of technologists, privacy advocates, government agencies, and the multi-billion dollar online advertising industry.

I will present the current status of both technical and non-technical attempts to ameliorate the problem. Economics might hold the key in increasing transparency of the largely hidden exchange of data in return for access of so-called free services.


Balachander Krishnamurthy is a member of technical staff at AT&T Labs--Research. His focus of research of is in the areas of Internet privacy, Online Social Networks, and Internet measurements. He has authored and edited ten books, published over 80 technical papers, holds thirty six patents, and has given invited talks in thirty five countries. He co-founded the successful Internet Measurement Conference and the Workshop on Online Social Networks. He has been on the thesis committee of several PhD students, collaborated with over seventy five researchers worldwide, and given tutorials at several industrial sites and conferences. His most recent book "Internet Measurements: Infrastructure, Traffic and Applications" (525pp, Wiley, with Mark Crovella), was published in July 2006 and is the first book focusing on Internet Measurement. His previous book 'Web Protocols and Practice: HTTP/1.1, Networking Protocols, Caching, and Traffic Measurement' (672 pp, Addison-Wesley, with Jennifer Rexford) is the first in-depth book on the technology underlying the World Wide Web, and has been translated into Portuguese, Japanese, Russian, and Chinese.
