Abstract

Today’s digital world requires us to access and protect computer information and interact securely with computer systems. Traditional methods for personal authentication such as physical key, ID card, secret password, PIN, …., etc. These methods suffer from various problems. Biometric measurements which mean biological features such as fingerprints, voice, face, hand geometry,…,etc. have a convenient and reliable solution to these problems. Recently, iris authentication has received increasing attention due to its high reliability for high security applications. The phasor demodulator is simply a four quadrant plane that maps the resulting feature matrix, from applying the normalized image to Gabor filter, to binary code. This mapping depends on the sign of both the real and imaginary part of the feature matrix. In this paper we show how to get Iris code with different Sizes using phase demodulator.

Item Type: Conference or Workshop Item (Paper)
Uncontrolled Keywords: biometrics, normalized image, iris features, Gabor filter, phase demodulator, iris code.
