Methods, systems and computer program products for eye based spoof detection

A system for eye-based spoof detection, the system comprising a processor implemented spoof detection controller configured for:

• illuminating an eye positioned within a field of view of an image sensor, with illuminating radiation from a first source of illumination located at a first position;
• illuminating the eye with illuminating radiation from a second source of illumination located at a second position that is spaced apart from the first position;
• acquiring at the image sensor, a set of images of the eye, wherein the set of images includes:
• a first set of image information corresponding to a first image region representing a first specular reflection at a third position relative to the eye;
• a second set of image information corresponding to a second image region representing a second specular reflection at a fourth position relative to the eye;
• determining based on image information corresponding to the acquired set of images, a difference value representing a difference between the third position and the fourth position;
• and
• generating a data signal representing detection of a real eye in response to determining that the difference value is less than a threshold value.

A computer program product for eye-based spoof detection, comprising a non-transitory computer readable medium having a computer readable program code embodied therein, the computer readable program code comprising instructions for:

• illuminating an eye positioned within a field of view of an image sensor, with illuminating radiation from a first source of illumination located at a first position;
• illuminating the eye with illuminating radiation from a second source of illumination located at a second position that is spaced apart from the first position;
• acquiring at the image sensor, a set of images of the eye, wherein the set of images includes:
• a first set of image information corresponding to a first image region representing a first specular reflection at a third position relative to the eye;
• a second set of image information corresponding to a second image region representing a second specular reflection at a fourth position relative to the eye;
• determining based on image information corresponding to the acquired set of images, a difference value representing a difference between the third position and the fourth position;
• and
• generating a data signal representing detection of a real eye in response to determining that the difference value is less than a threshold value.
