Digital Identity Management and Trust Negotiation
Abhilasha Bhargav-Spantzel
grad
CERIAS, Computer Science Department at Purdue University
( Elisa Bertino )

Most organizations today require the verification of personal information pertaining to users in order to provide service to users. Privacy of such information is of growing concern and because organizations often ask for similar information, this process can also be redundant and inefficient. Recent proposals dealing with federated identity management have the potential to alleviate such problems. A federation is a set of organizations that establish mutual trust with each other. This allows them to share client information whenever possible depending on their service disclosure policies and user privacy preferences. This work addresses such problem by integrating federated identity management with trust negotiation techniques. We focus on a trust negotiation approach suitable for federated environments. Our federated trust negotiation approach relies on the use of special-purpose tickets, that is, signed assertions that are released by the federation members to users upon successful negotiations. The main advantage of such integration is that if a user has already successfully negotiated with a member of the federation, subsequent negotiations with other federation members may require a reduced number of interactions between the client and the service provider.

Development of an open-source UPC/Nutrition Database with a handheld device
Diane Cessna
undergrad
Indiana University
( Kay Connelly )

We propose to develop an open-source, publicly available database that connects UPC codes to nutritional information. This will be done in two main stages. The first stage of the project is to develop the software to be used for updating and accessing the database. The second stage will consist of seeding the database with enough entries to demonstrate its usefulness to the public. In order to make this project a success, we must take steps to ensure the accuracy of our data and the willingness of the general public and research community to make entries.

The Power of the Admin Versus the Security of the User
Anne Faber
grad
Indiana University
( Minaxi Gupta and Kay Connelly )

End users are often regarded as the weakest link in cybersecurity. In particular, many end users run as administrators for day-to-day tasks, enabling cybercriminals to compromise their machines. This poster presents the design and evaluation of a user interface that guides the end user to configure and use their machine with limited privileges, rather than full privileges.

( Markus Jakobsson )

Do you have many friends?

Are all of them your true friends?

Maybe not!

Who knows?

The poster will illustrate the use of social engineering to mount a phishing attack on a network of friends, the results of the experiment, its possible outcomes and what we see as the future of phishing.

Automated Genome Annotation of R. centenum
Mira Han
grad
Indiana University

This project I am working on is part of the Phototrophic Prokaryotes Sequencing Project.

It is sequencing of multiple bacterial organisms related to the evolution of photosythesis. We will be working on the genome annotation of R. centenum. R. centenum is a thermotolerant purple bacteria that exhibits a complex life cycle involving differentiation from swim to swarm cells, and resting cysts. We aim to identify developmentally regulated genes involved in the differentiation.

My role in the project is to make the annotation process as automated as possible, using different software tools and bioinformatics methods. Annotation is a complicated process that requires various computational approaches from gene modeling, homolog detection to protein family clustering. I will be able to evaluate different systems and tools available in public during the process, and hopefully make an improvement in the annotation methods.

DCT-based Image Compression, An Analysis
Sarah Hegeman & Andrea Leichtman
undergrad
Rose-Hulman Institute of Technology
( Dr. Archana Chidanandan )

Work in Progress

Over the course of the 2005-2006 school year, Andrea, Sarah, and Joe Moder are looking into various popular transform-based image compression algorithms and architectures for the implementation of a low-power and high-throughput discrete cosine transform (DCT) computer architecture. Once they have gained a sufficient understanding of current methods, they will be implementing a novel architecture of their own. Towards this end, this work in progress has involved reading various journal articles and conference papers, exploring both old and new algorithms, and evaluating the efficiency of those architectures. The next stage of this project involves implementing certain architectures using the Verilog hardware description language and synthesizing them on FPGA. Their proposed novel architecture will be measured against popular methods in this way, resulting in a paper which will pull all of out research together.

Machine learning approach to predicting peptide fragmentation spectra
Narmada Jayasankar
grad
Indiana University

The objective of this project is to use automated techniques in order to learn peptide fragmentation rules in the form of posterior probabilities and then utilize the trained model for peptide identification. The original problem of predicting spectral peak intensities will be converted into a simpler and easy-to-interpret classification problem, in which the peak intensity is normalized and binned into two groups. Predictors of ion intensities will be constructed using ensembles of two-layer feed-forward neural networks, which, if provided with enough data, are known to be uni-versal approximators of bounded functions

Development of an open-source UPC/Nutrition Database with a handheld device
Christina Lirot
undergrad
Indiana University Computer Science
( Kay Connelly )

We are developing an open-source, publicly-available database that connects UPC codes to nutritional information. The main hurdle in this project is seeding the database with information. A typical grocery store has 10,000 to 40,000 different types of food. It is not practical to pay someone to manually enter all of the information. Instead, our approach will be to populate the database enough to show its usefulness, and then call upon the help of populations that would benefit from access to such a resource (i.e. people with allergies or other dietary restrictions).

Design CCA Common Interface for HPC libraries
Fang Liu and Yongquan Yuan
grad
Indiana University
( Randy Bramley )

We present the work we are doing for relieving the software complexity on high-end scientific computing by componenizing them. Under CCA framework, unit of software functionality are encapsulated as components which interact with each other only through well-defined interface. The interface we are working on are interface for parallel I/O libraries and interface for parallel linear solver libraries. Our goal is to make application easily switching the underneath libraries.

Mission Meal
Adity Mutsuddi
grad
Indiana University

(Project Members Michele Buddie, Arvind Ashok, Ankur Shah and Adity Mutsuddi)
(Poster Design Michele Buddie and Adity Mutsuddi)

We designed a system for children ages 6-8 using tangibles as part of the Pervasive Computing class last semester. The system was partially implemented. The system was designed to be placed in a classroom and be used under the supervision of a teacher.

The main goals of our project were to get children to try new foods and to get them involved in the preparation of food. We designed a system where the children could place tagged tangible simple food items into an RFID scanner. The screen then asked the child for the type of complex food (sandwich, pasta, etc.) she would like to eat.

The system then added a compatible food item (not selected by the child) to the list of simple food items selected by the child. The system used this list and the chosen complex food to find a suitable recipe and print it. The recipe is child friendly and contains details of getting the simple food items from the grocery store. It also contains information about the food items in the recipe as a talking point between the parent and child as the recipe is made. We hope the child will go back home and try out the recipe with the help of their parents.

Chick Clique
Tammy Toscos
grad
Indiana University
( Yvonne Rogers, Kay Connelly )

We are developing a preventative health cell phone application that helps motivate teenage girls to exercise by exploiting their social desire to stay connected with their peers. We targeted girls because they are more likely to become less active throughout adolescence and are more likely to use dangerous techniques for losing weight. The intent of Chick Clique is to provide information at opportune times in order to modify the behaviors of girls and ultimately lead to improved health habits. Our study investigated how collecting, sharing and comparing personal fitness information impacts activity level and health awareness.
