Positive identification or verification of identity of an individual is a major part of the security, legal, banking, and police task of granting or denying authority to take an action. Work is being done using IR facial imaging and computer technology to perform the human recognition task rapidly, accurately, and nonintrusively. Three basic principles have been demonstrated: every human IR facial image (or thermogram) is unique to that individual; an IR camera can be used to capture human thermograms; and captured thermograms can be digitized, stored, and matched using a computer and certain mathematical algorithms. A three- part development effort has been undertaken using IR facial recognition in an access control application. The first, an opertor assisted proof-of-concept effort, has been successfully completed. The second, an automated access control unit, has been completed and is undergoing independent testing in a simulated controlled access environment. Work on the third developmental effort is planned for this summer.
