In iris recognition, iris images are captured as matching templates and compared with matching samples. The acquisition of iris template needs some infrared auxiliary illumination to display iris texture, and it is coded by hardware or software. The corresponding code is iris template. After obtaining the iris template, grab the sample in real time and compare it with the template continuously. If the comparison is successful, the iris recognition is successful. At present, the speed of iris recognition can be very fast, which is equivalent to the speed of fingerprint unlocking.
Moreover, the iris texture is rich and varied, and the iris texture is different from person to person, so the safety level of iris recognition is very high.
