With increase in usage of the Internet, there has been an exponential
increase in the use of online social media on the Internet. Websites
like Facebook, Google+, YouTube, Orkut, Twitter and Flickr have
changed the way Internet is being used. There is a dire need to
investigate, study and characterize privacy and security on online
social media from various perspectives (computational, cultural,
psychological). Real world scalable systems need to be built to detect
and defend security and privacy issues on online social media. This
talk will give you a preview of what we do at PreCog
(http://bit.ly/preCOG) in the area of PSOSM. I will describe briefly
some of the cool ongoing projects that we have: ChaMAILeon, PhishAri,
Twit-Digest, U2P2, and OCEAN. Much of our research work is made
available for public use through tools or online services. Our work
derives techniques from Data Mining, Text Mining, Statistics, Network
Science, Public Policy, Complex networks, Human Computer Interaction,
and Psychology.

In this talk, I will focus on the following: (1) Twit-Digest
(http://bit.ly/precogTD) is a tool to extract intelligence from
Twitter which can be useful to security analysts.  Pro-cursor to this
work is published at PSOSM 2012, this work also obtained second best
award at IBM ICARE 2012. (2) OCEAN: Open source Collation of
eGovernment data and Networks (http://bit.ly/precogO). Here, we show
how publicly available information on Government services can be used
to profile citizens in India. This work obtained the Best Poster Award
at Security and Privacy Symposium at IIT Kanpur, 2013. (3) Privacy in
India: Attitudes and Awareness V 2.0 (http://bit.ly/15FNZSc) U2P2,
this is one of the largest ever done privacy study in India. This has
been in media recently; if you are interested search for
#privacyindia12 on Twitter.  This work obtained the third Best Poster
Award at Security and Privacy Symposium at IIT Kanpur, 2013.

He received his Ph.D. from the School of Computer Science at Carnegie
Mellon University (CMU). His research interests include developing
technological and inter-disciplinary solutions to detect and prevent
computer crime, in particular, these days be has been dabbling with
complex networked systems (e.g. social web systems like Twitter,
Facebook, and telephone logs). He is also very passionate about issues
related to human computer interaction. As Principal Investigator, PK
