Abstract

Video steganography is a technique used for secret communication. In video steganography, the secret information is concealed in a video file. An MP4 video steganography method that hides audio and image data in wavelet domain is proposed in this paper. A video file consists of I-frame, P-frame, and B-frame. An Iframe, or intra frame, is decoded independently without referencing other frames. P-frames and B-frames are responsible for capturing the motion. A number of I-, P- and B- frames together is called Group of Pictures or GOP. A GOP starts with an I-frame whose length (number of frames between two I- frames, excluding the second I-frame) varies depending on the codec used. Since I-frames are not lost during compression or any kind of signal processing operations, they are selected for embedding. Appropriate pixels of the I-frames and the audio frames are used for embedding without affecting the perceptual features of the video. Redundant copies of the secret information are made to avoid frame loss. The image frames hide the secret images and the audio frames hide the secret audio signals. The secret image and audio signals are transformed using integer wavelet transform and the low frequency coefficients are hidden. The performance is analyzed and the effect of common attacks is discussed.
