Scientists hid secret codes in light to combat video fakes

The article discusses a new technique developed by scientists to combat the growing problem of video fakery. Researchers have discovered a way to embed secret codes in the light patterns of videos, which can be used to verify the authenticity of the footage. The technique, known as "light-based watermarking," involves modulating the brightness of individual pixels in a video to create a unique digital signature. This signature can be detected and verified using specialized software, making it much harder for malicious actors to create convincing fake videos. The researchers emphasize that as video manipulation technology becomes more sophisticated, it is crucial to develop robust methods to ensure the integrity of digital media. By embedding these invisible codes in videos, they aim to provide a reliable way to distinguish real footage from fabricated content, helping to combat the spread of misinformation and maintain trust in visual information.
