Video Steganography

Hiding secret information inside videos without making it obvious.

Raw Domain Video Steganography

A technique that hides information within the video's raw data, directly manipulating the pixels of each frame.

Transform Domain Video Steganography

A technique that uses mathematical transformations to hide data within the video's frequency components.

Study Notes

Video Steganography

Video steganography is a technique used to hide secret information within a video file.

Raw Domain Video Steganography Classification

Raw domain video steganography is classified into the domain of multimedia security.

Transformation Methods in Raw Domain Video Steganography

Extensively used transformation methods in raw domain video steganography include Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT).

General Data Embedding Procedure

The general data embedding procedure in raw domain video steganography involves modifying the Least Significant Bits (LSB) of the video frames to embed the secret information.
