To identify a biometric sample quickly from a vast database, it is essential to develop effective and efficient mechanisms for controlling matching throughput, reducing false-match error, and enhancing security of the biometric templates.
We have proposed a mathematical modeling approach to address the above problems. In this talk, I will first describe the fingerprint orientation model, FOMFE, that we have published in IEEE Transactions on Pattern Analysis and Machine Intelligence, Special Issue on Biometrics: Progress and Directions. FOMFE can effectively describe the overall ridge topology, including the difficult singular point regions, even for poor quality fingerprints. It does not require any prior knowledge of singular points, which is a highly desirable feature. Then, I will show how we can exploit the model-based feature to develop an efficient indexing scheme for scalable fingerprint identification. I will also demonstrate another application of our modeling approach to the important problem of protecting fingerprint biometric templates. The relevant work of this part has been published in IEEE Transactions on Pattern Analysis and Machine Intelligence in 2011.
Yi (Alice) Wang received the BE degree from the School of Electronic and Information Engineering at South China University of Technology, Guangzhou, China, in 2002, the ME degree in telecommunications from the University of Melbourne, and the PhD degree in computer science from RMIT University, Melbourne, Australia, in 2003 and 2009, respectively. She is now a Research Associate with the School of Mathematics and Statistics and the School of Computer Science and Engineering, The University of New South Wales, Sydney, Australia. Her research interests include biometrics and statistical pattern recognition.
