Cornell University researchers have developed a method to “watermark” light in videos. This technique hides information within nearly invisible fluctuations of light during important events such as interviews, press conferences, or at locations like the United Nations Headquarters. The hidden watermark is recorded when video is captured under the special lighting, allowing fact-checkers to determine if footage has been manipulated or is fake.

Cornell University shared details about their research, which aims to assist in the fight against misinformation by ensuring the integrity of video evidence. Further information about the research can be found on the Cornell University website.
