After each data collection, we conduct a survey of our participants to find out how well we did. For the last study, over 90% of the participants were satisfied, or extremely satisfied with the test, test administrators, facilities, and the consent process. 2.5% were disappointed in the study, and the remainder were neutral. However, 100%…

Since 2001, we’ve been leading the way in the testing and evaluation of mobile devices. Here is the timeline of our activities: 2014 – voice recognition data capture on iPhone and Android 2012 – 2014 – NSTIC data capture on iPhone and Android 2012 – Eyevein capture testing on iPhone 2012 – Mobile biometrics evaluation…

Understanding Fingerprint Skin Characteristics and Image Quality from International Center for Biometric Research This research assessed the relationship of moisture, oiliness, and elasticity, age, temperature, and gender variables on fingerprint image quality. Fingerprint images from three different datasets, collected on one optical fingerprint sensor were used. Using Pearson correlations, linear regressions, and the process of…

ICBR Databases from International Center for Biometric Research We have just finished a 100 person test on voice recognition. We collected the data over a 5 day period, collecting from 8am to 8pm. Our main testing facility in Young Hall can be customized to any number of different types of layouts. Our new state of…

This semester, students will be replicating previous studies conducted in the center. A replication is vital in order for students to step through a process of conducting research where they know the results, and have a guide to complete the work. Replication is important, as it validates previous work, and increases potential generalizability. This page…

When we were designing the IT 34500 class structure, one of the ideas we had was to provide the content on-demand to the students. The question was, “which software should we use?” We have used a couple of software solutions before, including CamStudio and Boilercast. However, these didn’t really meet our needs. Recently, Microsoft released…

This semester, we are trying something a little different in the classes (IT 34500, IT 54500, IT 65800, IT 62100) that we teach. We have over the past 14 years, continued to develop the courses with new initiatives and ideas. These changes have been driven by both internal (Purdue) and external (technology) factors. Fourteen years…

    Michael Brockly’s M.S. thesis presentation for Purdue University, December 2013. This study created a framework to quantify and mitigate the amount of error that test administrators introduced to a biometric system during data collection. Prior research has focused only on the subject and the errors they make when interacting with biometric systems, while…

The International Center for Biometric Research has recently been featured in a video for the College of Technology. See the video below for a look into our daily life. “All of those cool biometrics technologies you see in movies are studied, tested and researched at Purdue University’s College of Technology. Undergraduate students are exposed to…

Stephen J. Elliott, Ph.D., director of the International Center for Biometric Research (ICBR) at Purdue University, will showcase the center and its work during a segment on NBC’s “Today” show Thursday morning, September 26 (at approximately 7:40 a.m. ET). Watch the story from the Today show. Elliott, professor of technology leadership and innovation in the…
