Imperfect Forward Secrecy: How Diffie-Hellman Fails in Practice

Imperfect Forward Secrecy

We investigate the security of Diffie-Hellman key exchange as used in popular Internet protocols and find it to be less secure than widely believed.

Face2Face: Real-Time Face Capture and Reenactment of RGB Videos

Face2Face

Face2Face is an approach for real-time facial reenactment of a monocular target video sequence. Our goal is to animate the facial expressions of the target video by a source actor and re-render the manipulated output video in…

Technical Perspective: Photorealistic Facial Digitization and Manipulation

If facial performance capture is possible for conventional RGB videos in real time, then believable facial expressions can be transferred effortlessly from one person to another in a live-action scenario. This capability is demonstrated…
