The computer vision community has created a technology which unfortunately is getting more bad press then it is good.In 2014, the first GANS paper was able to automatically generate very low resolutions of faces of people which never existed, from a random latent distribution.Although the technology was impressive because it was automated, it was now where near as good as what could be done with the simple photo editor. In the same year DARPA started the media forensics program to combat the proliferation of edited images and video that was benign generated by our adversaries. Although DARPA envisioned the development automated technologies, no one thought they would evolve so fast. Five years later the technology has progressed to the point where even a novice can modify full videos, i.e. DeepFakes, and generate new content of people and scenes that never existed, overnight using commodity hardware. Recently the US government has become increasingly concerned about the real dangers of the use of "Deep Fakes" technologies from both a national security and a misinformation point of view. To this end, it is important for academia, industry and the government to come together to apply technologies, develop polices before we get to the point where "seeing is believing" is a thing of past. In this talk I will cover some of the primary efforts in applying counter manipulation detection technology, the challenges we face with current policy in the United States. While technological solutions are still a number of years away, we need a comprehensive approach to deal with this problem.
