Video Steganography

A subject embeds data within a video file or video stream to conceal sensitive information inside apparently legitimate visual or audiovisual content.

Video files provide multiple locations for hidden data, including individual frames, color values, compression coefficients, motion data, audio tracks, subtitles, metadata, and unused container structures. A subject may distribute a payload across many frames or components, reducing the amount of alteration applied to any single part of the file.

The resulting video may appear and play normally while carrying documents, source code, credentials, records, archives, or other organizational data. The subject may transfer the video through email, cloud storage, messaging platforms, or media-sharing services where large audiovisual files are expected.
