Abstract :
This paper presents an entirely automatic system designed to realize accurate and fast personal identification from the iris images acquired under open environment. The acquisition device detects the appearance of a user at any moment using an ultrasonic transducer, guides the user in positioning himself in the acquisition range and acquires the best iris image of the user through quality evaluation. Iris recognition is done using the bandpass characteristic of wavelets and wavelet transform principles for detecting singularities to extract iris features and adopting Hamming distance to match iris codes. The authentication service software can enroll a user´s iris image into a database and perform verification of a claimed identity or identification of an unknown entity. The identification rate is high and the recognition result is available about 6 s starting at iris image acquisition. This system is promising to be used in applications requiring personal identification.
