Abstract

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. I will describe briefly some cool ongoing and recently completed projects that we have: TweetCred, Finding Nemo, OCEAN, Privacy in India, and Call Me MayBe. Many 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 particular, in this talk, I will focus on the following: (a) TweetCred is a tool to find credibility of tweets on Twitter. TweetCred is backed by award-winning research publications in international and national venues. (b) Finding Nemo, where we identify given a twitter handle the equivalent Facebook handle. This addresses the problem of identity resolution in online social media. Both TweetCred and identity resolution problems have been the basis for 2 Ph.D. theses awarded at IIIT Delhi. (c) OCEAN: Open source Collation of eGovernment data and Networks 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 and it has gained a lot of traction in Indian media. (d) I will also discuss about one of the largest privacy studies done in the world; we collected data from 10,427 participants all across India. I will also describe some of the other projects that we are currently involved in. I will be more than happy to clarify, discuss, any of our work in detail, as required, after the talk.
