Face Presentation Attack Detection a.k.a Face Antispoofing

Face recognition is one of the most convenient biometric for access control. The wide popularity of face recognition can be attributed to ease of acquisition with cheap sensors, contact-less nature, high accuracy of algorithms, and so on. While everything is well and good there, the vulnerability to presentation attacks limits its use in safety-critical situations. Imagine your phone locked with face recognition being unlocked by someone simply showing a photo or video of you in front of the phone. There you have it, its called a presentation attack (also known as spoofing attacks).
