Video Steganography is a technique to hide any kind of files in any extension into a carrrying Video file.This project is the application developed to embed any kind of data(File) in another file, which is called carrier file. The carrier file must be a video file. It is concerned with embedding information in an innocuous cover media in a secure and robust manner. This system makes the Files more secure by using the concepts Steganography and Cryptography.
An input content signal, e.g., representing video, is encoded to hide plural-bit auxiliary data therein. The process generates an intermediate signal that is a function of (a) the plural-bit auxiliary data, and (b) data related to human perception attributes of the content signal. This intermediate signal is then summed with the content signal to effect encoding. The plural-bit auxiliary data can include copy control data, i.e., data that can be sensed by a consumer electronic device and used to disable a copying operation. The intermediate signal may include a pseudo-random key signal so as to obscure the encoding and require knowledge of a corresponding key at the decoder to extract the auxiliary data from the encoded content. In some embodiments, calibration data is encoded in the content signal with the auxiliary data. This calibration data desirably has known properties (e.g., spectral attributes, data content, etc.) facilitating its identification in the encoded content signal. The encoding is desirably robust against various forms of content degradation, e.g., lossy compression/decompression, scaling, resampling, conversion from digital to analog and back again, etc., so that the auxiliary data can be detected from the content notwithstanding such corruption.
