Abstract
Techniques for authenticating digital media asset, and particularly to verifying the authenticity of digital image or video files which may have been redacted or otherwise altered in some way. The approach, which we call perceptual video fingerprinting, compares media assets based on what humans perceive, rather than exactly which bits match, by using neural network algorithms.
