Exploring the Vulnerabilities of PRNU-based Camera Fingerprinting

Photos taken with a digital camera carry imperfections imperceptible to the human eye, but which can be deduced using image processing techniques. It is possible to link these imperfections to a single camera, which raises privacy concerns. Watch this video to learn about our approach to suppress this camera-identifying information from images.

Iris Anti-Spoofing: Detecting Presentation Attacks

Iris biometric systems are vulnerable to “spoofing,” where adversaries attempt to trick the system with a fake iris. Watch this video to learn about our approach to defending against these attacks!

DeepTalk: Vocal style transfer for realistic speech synthesis

Speech synthesis, the generation of artificial speech from an input, remains a difficult and well motivated task. In this video, we discuss how deep learning based natural language processing can be used to help generate realistic speech. For more, see:
