Abstract

We developed an algorithm to estimate the optical properties of a bilayer material using diffuse reflectance analysis. This algorithm has been tested to the detection of liveness in a biometric device adapted to perform Structured Light Imaging. The liveness detection is based on the optical properties comparison between spoofs and living objects.
