Steganography is a technique centered on concealing a secret message within a seemingly harmless file, such as an image, audio clip, or video, with the primary goal of hiding the very existence of the information. Unlike encryption, which only protects the content from being read, steganography ensures that the presence of the hidden message is undetectable to unintended recipients. This method leverages subtle alterations to the carrier medium that remain imperceptible to human senses, maintaining the natural appearance and integrity of the file. In video steganography, secret data—often in the form of text—is embedded into a video file in such a way that it does not affect the viewer's perception of the video. Techniques such as manipulating the least significant bits (LSB) of pixel values or making minor adjustments to audio data are employed to achieve this invisibility. The hidden information could range from a short phrase to large blocks of text or even multimedia content, and must be embedded carefully to ensure that neither the visual nor the auditory components of the video are noticeably altered. One of the critical challenges of video steganography lies in maintaining both the undetectability and quality of the stego-video. Advanced embedding methods are needed to resist detection by steganalysis tools while preserving the structural integrity and performance of the video. Compared to image or audio steganography, video steganography benefits from the dual nature of video files— visual and auditory—offering more capacity for hidden messages but also presenting more complexity in safeguarding against detection. This dual-layered environment provides a robust and versatile platform for securely transmitting confidential information
