Project Title: Using Biometrics to generate Public and Private Keys
Semester: Spring 2006
Committe Chair: Dr. Mario Garcia
Committee Member 1: Dr. David Thomas
Committee Member 2: Dr. Long-zhuang Li
Project Description: In traditional cryptographic systems, user authentication is based on possession of secret keys. This system falls apart if the keys are not kept secret (i.e., shared with non legitimate users). Considering the need for heightened security all over the world, just having a secret key is not a viable solution. Most of the secret keys are shared, written down, forgotten, lost or stolen, or just not complex enough. This is where biometrics can help because biometrics isnít tied to a secret key but to the physical body demographics or behavioral ways. Current authentication systems based on physiological and behavioral characteristics of persons, such as fingerprints, inherently provide solutions to many of the above mentioned problems and may replace the authentication component of traditional cryptosystems. This project produces the cryptographic keys which are bonded with the fingerprint of a user. Such cryptosystems provide better security as the key cannot be compromised without an authenticated user.
