CS Colloquium: Yeongjin Jang (Georgia Tech) - Protecting Computing System Interactions
Tue, Mar 28, 2017 @ 11:00 AM - 12:20 PM
Thomas Lord Department of Computer Science
Conferences, Lectures, & Seminars
Speaker: Yeongjin Jang, Georgia Tech
Talk Title: Protecting Computing System Interactions
Series: CS Colloquium
Abstract: This lecture satisfies requirements for CSCI 591: Computer Science Research Colloquium.
Computing platforms are evolving from desktops to Smartphones to the Internet of things (IoT) devices. In this change, computer systems have started embedding an amazing variety of interaction points in both software and hardware forms. While such changes have made everyday life easier by enabling various convenient features, protecting these systems has become much more difficult. This is not only because system complexity has increased with the integration of more interactions and often conflicts with the existing security mechanisms, but also because improper security practices or incomplete security checks result from faster production cycles that generally lead to more security holes.
In this talk, Yeongjin will present his research on protection of computing system interactions. First, he will present Gyrus, a user interaction monitoring system that reflects user's intention to network traffic monitoring. Gyrus can protect user-to-network interactions such as sending message online and online banking. Next, he will present a result of security analysis on user I/O in operating systems,
in which he discovered computer accessibility as a new attack vector. The analysis found 12 new attacks in popular operating systems, and he discusses countermeasures against the vulnerabilities to keep the affected systems secure.
Biography: Yeongjin Jang is a Ph.D. candidate in Computer Science at the Georgia Institute of Technology. His research focuses on security and privacy problems of computing systems, which include operating systems, mobile systems, and computing hardware.
His research results are recognized for their highly practical impact, as noted by one award and two nominations for the CSAW best applied research paper. Moreover, his research has been widely covered in popular media including Forbes, Wired, MIT Technology Review, and more.
Yeongjin received his M.S. from Georgia Tech in 2016 and B.S. from KAIST in 2010.

Title: Demographic Bias Correction for Social Media Data
PhD Candidate: Christopher Wienberg
Date and Time: Tuesday, March 28th, 11:00am
Location: Zumberge Hall (ZHS) 360
Abstract:
For generations, people have been keeping records of their everyday lives. The web is now a popular place for people to document their personal lives, replacing journals and diaries popular decades ago. The popularity of weblogs and social media has provided an unique opportunity to study people at a massive scale. Social media researchers have seized this chance to use social media data to predict and measure social phenomena, such as elections, economic activity, and public health. While these researchers' work has shown promise, they frequently highlight a challenge with web data: web users, as a group, are dissimilar (e.g. younger, wealthier) from most offline populations.
Demographic representativity is an issue that economists and other social scientists deal with regularly. They have found that re-weighting survey samples based on demographic variables like age and gender can improve the accuracy of survey results. They directly account for this need by asking survey respondents to provide their demographic background. In contrast, social media analysts do not have immediate access to these demographic variables.
This dissertation proposes and evaluates a practical approach for making social predictions from social media data while contending with demographic representativity issues. It describes the collection and analysis of reliable data describing a population of web users. Social predictions are drawn from this population, with various bias correction techniques evaluated by comparing to gold standard data from traditionally collected surveys. Special attention is paid to important practical considerations, such as errors introduced by automated methods to characterize the demographic and other attributes of individual users and their impact on predictions for the broader population.
