CSE Students defend Ph.D. Dissertations

Dr. Roopa Vishwanathan and her dissertation committee

Roopa Vishwanathan defended her dissertation "Exploring Privacy in Location-based Services Using Cryptographic Protocols" on November 22, 2010. In the picture above, from left to right, are Dr. Yan Huang, major professor and associate CSE professor; Roopa Vishwanathan; Dr. Steve Tate, former UNT CSE faculty member and now head of the Computer Science Department at the University of North Carolina at Greensboro; Dr. Armin Mikler, associate CSE professor; and Dr. Bill Buckles, CSE professor.

Dissertation Abstract: Location-based services (LBS) are available on a variety of mobile platforms like cell phones, PDA's, etc. and an increasing number of users subscribe to and use these services. Two of the popular models of information flow in LBS are the client-server model and the peer-to-peer model, in both of which, existing approaches do not always provide privacy for all parties concerned. In this work, we study the feasibility of applying cryptographic protocols to design privacy-preserving solutions for LBS from an experimental and theoretical standpoint. In the client-server model, we construct a two-phase framework for processing nearest neighbor queries using combinations of cryptographic protocols such as oblivious transfer and private information retrieval. In the peer-to-peer model, we present privacy preserving solutions for processing group nearest neighbor queries in the semi-honest and dishonest adversarial models. We apply concepts from secure multi-party computation to realize our constructions and also leverage the capabilities of trusted computing technology, specifically TPM chips.

We prove our constructions secure under standard cryptographic assumptions and design experiments for testing the feasibility or practicability of our constructions and benchmark key operations. Our experiments show that our constructions are practical to implement and have reasonable costs, while providing strong privacy assurances.

Dr. Chengyang Zhang and his dissertation committee

On January 3, 2011, Chengyang Zhang successfully defended his dissertation "Toward a Data-Type-Based Real Time Geospatial Data Stream Management System." Dr. Yan Huang served as his major professor and dissertation advisor. In the picture above, from left to right, are Dr. Xinrong Li, associate professor in the Department of Electrical Engineering; Dr. Bill Buckles, professor in the CSE Department; Chengyang Zhang, Dr. Yan Huang, associate CSE professor; and Dr. Armin Mikler, associate CSE professor.

Dissertation Abstract: The advent of sensory and communication technologies enables the generation and consumption of large volumes of streaming data. Many of these data streams are geo-referenced. Existing spatio-temporal databases and data stream management systems are not capable of handling real time queries on spatial extents. In this thesis, we investigated several fundamental research issues toward building a data-type-based real time geospatial data stream management system. The thesis makes contributions in the following areas: geo-stream data models, aggregation, window-based nearest neighbor operators, and query optimization strategies. Our proposed geo-stream data model is based on second-order logic and multi-typed algebra. Both abstract and discrete data models are proposed and exemplified. We further propose two useful geo-stream operators, namely Region By and WNN, which abstract common aggregation and nearest neighbor queries as generalized data model constructs. Finally, we propose three query optimization algorithms based on spatial, temporal, and spatio-temporal constraints of geo-streams.

We show the effectiveness of our data model through many query examples. The effectiveness and the efficiency of the algorithms are validated through extensive experiments on both synthetic and real data sets. Our work established the fundamental potential impact in many applications such as hazard weather alerting and monitoring, traffic analysis, and environmental modeling.

Yiwen Wan
Yiwen Wan and colleagues assembling traffic surveillance equipment on Loop 288
It was announced in December that Yiwen Wan will be presented the Wanda J. Shafer Graduate Scholarship at the March meeting of the local chapter of WTS (Women in Transportation Seminar). The Wanda J. Shafer Graduate Scholarship was established in 2002 in honor of the first chapter president of the Dallas/Fort Worth chapter. Each year, only one such scholarship is awarded to a graduate student in the Texas-Oklahoma region.

As evidence of her contribution, Ms. Wan submitted a video-based traffic surveillance system for which she leads the development. Specifically designed for remote locations, the system communicates via wireless to the base station. The camera autonomously calibrates and, in addition to collecting traffic statistics, watches for incidents.

Ms. Wan is currently a Ph.D. student in the Department of Computer Science and Engineering, working in the Computer Vision Lab. Under the guidance and instructions of Dr. Huang and Dr. Buckles, she and Ning Luo have been cooperating on a project sponsored by TxDOT. Ms. Wan's research interests are image processing, computer vision, pattern recognition and data mining. In the future Ms. Wan hopes to contribute to the progress of intelligent transportation systems and security surveillance systems to help build safer and smarter cities.

Ms. Wan is grateful that her group has made great progress on the TxDOT project and thanks all of her group members. She would like to thank UNT for all their support and help they offered to build the wireless monitoring system at Discovery Park and on main campus. She is also grateful that WTS has been creating great opportunities for advancing the careers of women in transportation.
