RECOD Mobile Presentation-Attack Dataset (RECOD-MPAD)

<p>=============<br> Introduction</p> <p>The RECOD Mobile Presentation-Attack Dataset (RECOD-MPAD) is intended for the study of presentation attacks (PAs, also known as spoof attempts) to facial recognition systems in mobile devices.<br> It consists of frames depicting genuine attempts of unlocking a smartphone, as well as two types of presentation attacks: using printouts of the user face;&nbsp;or using electronic displays showing the user&#39;s face.</p> <p>More details can be found in the accompanying paper:<br> <em>Detecting face presentation attacks in mobile devices with a patch-based CNN and a sensor-aware loss function</em><br> Waldir R.
