This paper proposes a video steganography algorithm based on Haar Integer Wavelet Transforms (IWT) and Least Significant Bits (LSB) substitution for data hiding and extraction in Red Green Blue (RGB) components of the video files. In this approach, the cover-video is divided into RGB frames and the text in binary form is embedded into the LSBs of IWT coefficients. The embedded text is extracted from stego-video using the reverse process of data hiding. The proposed system was implemented using Audio Video Interleave (AVI) files. The experimental results prove that the proposed system has shown imperceptible modifications in AVI videos that lead to high security and an eavesdropper’s inability to detect hidden data. The proposed system is simple and therefore can be used to transfer highly confidential data like military secrets, hospital reports and other data.
