안녕하십니까?
융합과학기술대학원입니다.
5월 30일(수) 오후 1시부터 디지털정보융합학과에서 아래와 같이 2개의 세미나(시간 : 1시 / 2시30분)가 있을 예정이오니, 관심있는 분들의 많은 참여바랍니다.
1) Title : Humane Information Retrieval: Going beyond the IR Way
Speaker : Jin Young Kim
Date & Time : 2012. 5. 30(수) 오후 1시
Where : 융기원 A-103호
Abstract
Much previous work in information retrieval (IR) has focused on ranking documents given a user"s query and on evaluating the outcomes with standardized test collections and metrics. However, it has been recognized that many applications of information retrieval in the real world cannot be fully captured by this abstraction.
In this talk, I will present two extensions to the simple model of previous IR research can be extended: rich user modeling and interactive IR. I first introduce my dissertation research, which employs rich interaction and user modeling for improving personal search. Then I describe some of my recent projects about book and web search, focusing on how users combine multiple modes of interaction, and how user profiling can improve both search and recommendation algorithms.
Biography
Jin Young Kim is a Ph.D candidate in UMass Amherst Computer Science, working in Center for Intelligent Information Retrieval with Prof. Bruce Croft on the intersection of information retrieval (IR) and human-computer interaction (HCI) research. Starting from September 2012, he will start as a Applied Researcher at Microsoft Bing. He frequently writes about his research at http://lifidea.tistory.comand @lifidea.
2) Title : Prototypes for invisible passwords: making interaction at public terminals more usable and secure
Speaker : Andrea Bianchi
Date & Time : 2012. 5. 30(수) 오후 2시 30분
Where : 융기원 A-103호
Abstract
Passwords in public spaces (such as PIN at bank ATMs, or login sessions on mobile phones) are inherently exposed to attacks based on observation, an increasingly common and damaging approach. In fact, the main weakness of commonly used passwords is that they are visible and an attacker can steal them by simple observation (a.k.a. shoulder-surfing) or by placing small hardware devices (skimmers) on a terminals used by customers. In this talk I will introduce to the audience a series of techniques and prototypes that can be used to defeat observation of passwords in public spaces. I will start showing to the audience how haptic and audio, two commonly used "invisible" modalities, can be employed to create reliable PIN entry systems. I will then show other interfaces based on mobile devices that as well try to make futile any attempt to perform an observation attack. I will hence discuss the state of the art techniques for invisible passwords and, basing my analysis on the results of user studies, I propose design guidelines for new, usable and secure password entry systems.
Biography
Andrea Bianchi received his B.S. degree in Business Administration from Universita" Bocconi, Milano, Italy, in 2004, his M.S.in Computer Science from New York University in 2007, and his Ph.D. degree from KAIST Graduate School of Culture Technology (field of Human Computer Interaction) in 2012. In 2007 he worked for Rebel Monkey, a New York based video game company, as lead game programmer on a casual game title. During his Ph.D he also worked as visiting researcher in the University of Madeira, Portugal (Carnegie Mellon Europe program) and EPFL, Switzerland. His main research interest is in Human Computer Interaction, physical computing and interaction design. His work on "haptic passwords" was recently featured on the New Scientist magazine, Engadget and ZDnet.
