![]() University of Notre Dame researchers have developed a new algorithm for detecting iris presentation attacks using a photometric stereo method. The performance of current commercial recognition systems is significantly lowered when presented with a textured contact lens compared to a normal iris. Iris recognition systems can be susceptible to presentation attacks, where an individual uses cosmetic contact lenses to conceal their identity or impersonate the identity of another.
