Systems And Methods For Spoof Detection In Iris Based Biometric Systems |
| 摘要 |
The invention provides methods, systems and computer program products for spoof detection in iris based biometric recognition. In an embodiment, the invention comprises (i) obtaining a first image of an iris at an imaging apparatus configured to a first exposure setting (ii) obtaining a second image of the iris at the imaging apparatus configured to a second exposure setting (iii) comparing incidence of reflection patterns within the first and second iris images and (iv) determining authenticity of the imaged iris based on a result of comparing the incidence of reflection patterns within the first and second iris images. |
