Abstract
A method and system for protecting video and image files processes from original files to detect skin tones of persons appearing in the media. Pixels determined to contain skin tones are blurred or blacked out, and the pixel locations and their original color values are stored in a metadata file. The metadata file is encrypted and stored with the redacted video file. Thereafter, when an authorized person wants to see an unredacted version of the video, the system decrypts the metadata and reconstituted the video, replacing the redacted pixels with their original color values, and inserting a unique watermark into the video that identifies the requesting person. The watermarked video is then provided to the requesting person.
