PARAPH: Presentation Attack Rejection by Analyzing Polarization Hypotheses

no code implementations10 May 2016 Ethan M. Rudd, Manuel Gunther, Terrance E. Boult

Thus, there is great demand for an effective and low cost system capable of rejecting such attacks. To this end we introduce PARAPH -- a novel hardware extension that exploits different measurements of light polarization to yield an image space in which presentation media are readily discernible from Bona Fide facial characteristics.
