A Review on Iris Liveness Detection Techniques

Iris recognition systems have been widely deployed for authentication in many sensitive security areas for their accuracy and consistency. However, as the iris technology evolves, ways to attack it evolve too. Fake iris samples could be used to spoof the iris recognition system. As a result, Iris liveness detection methods have been developed. These methods read the users physiological signs of life to verify if the iris pattern acquired for identification is fake or real. In this paper, a review for the previous work done in iris liveness detection is presented.
