Robust Detection of Textured Contact Lenses in Iris Recognition Using BSIF

James S. Doyle, Kevin W. Bowyer
2015 IEEE Access  
This paper considers three issues that arise in creating an algorithm for robust detection of textured contact lenses in iris recognition images.  ...  One issue is whether accurate segmentation of the iris region is required in order to achieve accurate detection of textured contact lenses.  ...  For this particular problem of textured contact lens detection, BSIF appears to offer substantially better performance. BSIF accuracy is generally higher, and generalizes better.  ...

An Intelligent Approach for Anti-Spoofing in a Multimodal Biometric System

P. Devakumar, R. Sarala
2017 International Journal of Advanced Research in Computer Science and Software Engineering  
The extracted biometric features are fused and fed to a convolution neural network that employs deep learning to detect spoofed features from real features.  ...  The proposed method is designed to overcome spoofing in a multimodal biometric system that uses a combination of face, fingerprint and iris images.  ...  The iris spoofing methods include iris images, photographic surfaces, fake glass or plastic eye and iris texture printed on contact lenses.  ...
