Abstract

Biometric user authentication using the face has been applied mainly to access control systems. However, access is allowed even when a photo is presented instead of an actual face. This can facilitate illegal access including attending as a substitute or substitute authentication. An alternative approach has been implemented to solve this problem. The approach determines between a real face and a photo of a face using a UV sensor but this requires substantial cost and installation process because additional hardware (the UV sensor) is necessary. This paper proposes a three-step approach to identify between a real image and a photo. Step 1 determines authenticity using the background data and eliminating the face data. Step 2 determines authenticity using eyelid blinking on the face and facial gestures. Step 3 authorizes the user by extracting the feature points on the face.
