Iris Verification Algorithm Based on Texture Analysis and its Implementation on DSP

This paper presents a Digital Signal Processor (DSP)implementation of the iris verification algorithm. Aninnovative method is presented to extract the iris features based on texture analysis. The algorithm was evaluated using CASIA iris image database version 1.0 [1]. Experimental results show that the approach has achieved high accuracy of 98.62%. The iris verification algorithm is designed to suit for DSP implementation. Templates are encoded in binary format because they are compact in size and can avoid the visibility of the individual iris images. The binary templates can be stored and processed effectively using DSP technology. The iris verification system is realized on state-of-the-art Analog Devices ADSP-BF561 to achieve fast verification performance. DSP technology provides a cost effective, low power and fast authentication solution within a compact hardware module.
