In this paper, the authors present an efficient biometric algorithm for iris recognition using fast Fourier transform and moments. Biometric system provides automatic identification of an individual based on a unique feature or characteristic possessed by the individual. The fast Fourier transform converts image from spatial domain to frequency domain and also filters noise in the image giving more precise information. Moments are area descriptors used to characterize the shape and size of the image. The moment's values are invariant to scale and orientation of the object under study, also insensitive to rotation and scale transformation.
