Title: Internet privacy: It is not getting better


Internet privacy has become a hot topic recently with both the advent of
Online Social Networks and a significant amount of publicity related to
privacy. For the last few years we have been examining the leakage of
privacy on the Internet: how information related to individual users is
aggregated as they browse seemingly unrelated Web sites. Our results
show increasing aggregation of user-related data by a steadily
decreasing number of entities. I will present results from three studies
on leakage of personally identifiable information (PII) via Online
Social Networks (both traditional and mobile OSNs) and popular non-OSN
sites. I will also present the current status of both technical and
non-technical attempts to ameliorate the problem.


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
twenty nine patents, and has given invited talks in over thirty
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. Bala is homepageless
and not on any OSN but many of his papers can be found at
