    Collective Aspects of Privacy in the Twitter social network

    With an increased online participation on Social Media, privacy concerns have risen to unprecedented levels. It has become extremely important to allow individuals the full control of their private information. Popular mobile applications integrated with Online Social Networks (OSNs) allow them to access user’s private information like their contact lists. This might allow OSNs to create shadow profiles of non-users using the data of existing users. We test this hypothesis for the first time on Twitter and further evaluate the predictability of location and biographical vector of a user from the information given by a friend who has created a Twitter Profile before our user. Dataset To get an unbiased…

    PreCog : The Google of Research Groups

    I feel ecstatic to write this blog post today as I complete an year at PreCog. I would like to use this opportunity to write about my journey till and through PreCog, with all the fantastic and memorable experiences I’ve had during this time. Jump to section III to know why I think PreCog is the ‘Google of Research Groups’. I. Getting In It was late 2015 and I had barely started my second year in college when I decided I wanted my UG life to have as many diverse experiences as possible. So, I started participating in various activities in college, which included founding and heading a student chapter…

    The journey of an unlikely doctor

    My journey at IIIT-Delhi started back in July 2010. To put things in perspective, that was the year when Steve Jobs introduced iPhone 4 and the first ever iPad. Game of Thrones was a TV series unheard of. Sachin Tendulkar scored the first ever double hundred in a one day cricket match. Barack Obama had just completed 1 year as the president of the United States. And Tinder and Instagram did not exist. The past seven years have taught me more about myself than I could ever expect to learn probably during the rest of my life. I learned what I want to do in life. More importantly, I learned…

    Precog 101

    In the summer of 2016, I was a third year Computer Science engineering student at the College of Engineering, Guindy in Chennai desperately looking for a summer internship. A chance encounter with a senior from college, who was then a Research Associate (RA) here, is how I first heard of Precog. What followed was a year long journey in which I’ve gained mentors, friends and an admit at the Ohio State University for the MS in CSE program (Let me assure you that my time at Precog is what got me in). Here I try to summarize my observations on what makes Precog awesome. What makes Precog Precog? Extreme organization. After working…

    Precog: A to Z

    Hi, all. I (Kartik Sethi, B.Tech. Final year at BITS Pilani, Hyderabad Campus) interned at the Precog Research Group of IIIT Delhi in the summers of 2017 (May – July). I have tried to express my experiences through the following paragraphs. A – Amazing was the word, which flashed in my mind when the programme started. B – Best environment and bonhomie was the hallmark of the internship. I found the environment and infrastructure in IIIT as one of the best in any such institution. C – Challenges. Every difficult problem is usually entailed with an innovative solution and every new solution is associated with challenges of its own. I…

    The Journey Known as Precog

    I was interested in Precog long before Precog was interested in me. Ever before I joined IIIT-Delhi, I had an innate fascination with the field of Security – especially how it affected us all in the digital age. So imagine my delight when I found out that IIIT-Delhi had an entire centre dedicated to Security, a.k.a, CERC (Cybersecurity Education and Research Centre). Among the several research groups that formed CERC, one of them was Precog. What interested me most about Precog was its focus on security and privacy, especially in the context of online social media. To me this seemed like an issue which was of vital importance, especially given…

    Precog: The Quintessential Group

    As curtains drew on the summer vacations of 2016, I was already planning on doing something constructive during my next summers. My mentor at IIT Kharagpur sent me a circular about an internship opportunity at a research lab in IIIT-Delhi. This is how I first got to know about professor Ponnurangam Kumaraguru and this supercool group known as Precog! I found the work in conformity with my interests and applied at once. After some rigorous technical rounds and interviews, I was informed of my selection. On 8th May 2017, I joined the group. Having got hostel accommodation at IIIT-Delhi itself, I got settled in my room. Soon after, PK invited…

    Pages from a chapter called Precog

    Back in 2014, when I came to know about Dr. PK, he was associated with Backpack, FindAWay, IDEA and other cool things that were going around the campus. It was very intriguing because I did not know much about him except that and the courses that he took. Little later, I found out about Precog, the research group that he has at IIITD. For me, Precog was this intimidating elite group that I would never be able to be a part of. But oh! how wrong was I and so are you if you ever felt that. Trust me, I am an insider. 😛 Fast forward to 2015, I saw…

    Precog: A Family Affair

    Before joining IIIT-Delhi, my father and I sat together to go through the list of faculty members who would teach me. We were awed by them all but some names stood out, one being PK’s. I read about his achievements and was eager to enroll in one of his courses when I joined IIIT-Delhi. After completing my first year, I was presented with several domains within computer science which I did not know existed; I wanted to explore them all. During the same time, Backpack was a hot product which students and professors were gushing about. I was told that a few of PK’s students had created Backpack and my…

    A stay of 2 months: An experience of lifetime

    Like every engineering student, when I took admission in engineering college I had high hopes and ambitions of doing something big and worthy. But the monotonous curriculum, seniority dogma, student-faculty gap never provided conducive environment for research and those high ambitions somehow faded away. Engineering seemed to be limited to only what was there in textbooks. However when I finished my summer internship this year (2017) at Precog, I suddenly experienced a revival of my engineering ambitions. People around were working and building stuffs that are being applied to solve real world problems and being one of them was like dream come true! My stay at precog was the most enriching part…
