Early life and educationIoannis A. Kakadiaris received his B.Sc. in Physics (1989) from the University of Athens. After moving to the United States, he received M.Sc. in Computer Science (1991) from Northeastern University (Boston, MA) and his Ph.D. in Computer Science (1997) from the University of Pennsylvania (Philadelphia, PA). Identity verification systemThe system works by extracting a unique biometric signature of a person's face based on combination of 3D shape, texture, infrared, and time variables. While earlier face recognition methods have focused on appearance - capturing, representing, and matching facial characteristics as they appear on 2D images in the visible spectrum, the proposed URxD system uses a webcam to capture a continuous video stream which is used to detect whether a person is facing the 3D camera, and if the subject is facing the camera relatively still for more than two seconds, the system triggers the optical scanner and the 3D data are captured. It can also determine whether the person is wearing glasses. The system has achieved the best published results when tried to 4,007 datasets as a part of the international face recognition Grand Challenge organized by NIST in 2007.{{Citation needed|date=September 2011}} References1. ^{{cite web | url=https://www.grasp.upenn.edu/news/grasp_alumnus_ioannis_kakadiaris | title=GRASP Alumnus, Prof. Ioannis Kakadiaris, Named Hugh Roy And Lillie Cranz Cullen Professor | publisher=University of Pennsylvania | date=14 September 2011 | accessdate=5 March 2014}} External links
