STATIC VIDEO [STEGANOGRAPHY]
ANY TYPE OF FILE TO STATIC VIDEO
What is Steganography?
The word Steganography is derived from two Greek words- ‘stegos’ meaning ‘to cover’ and ‘grayfia’, meaning ‘writing’, thus translating to ‘covered writing’, or ‘hidden writing’. Steganography is a method of hiding secret data, by embedding it into an audio, video, image, or text file. It is one of the methods employed to protect secret or sensitive data from malicious attacks.
What is Video Steganography?
It is an approach of concealing some kind of documents or information into computer video format. In this method, video (set of pictures) can be used as carrier for hiding the information. Generally discrete cosine transform (DCT) insert the values (such as 8.667 to 9) which can be utilized to conceal the data in each of the images in the video, which is unnoticeable by the human eye. H.264, Mp4, MPEG, AVI are the layout used by video steganography.
Before going to methodology let analyze How Static video divided into Binary format.
1.Static video
The random pixel pattern is superimposed on the picture, being visible as a random flicker of “black and white”, “dots”, “snow” or “fuzzy zig-zags” in static video such that (0, 0, 0) is no light, and thus black, and (1, 1, 1) is all light, and thus white.
2.Frames
A frame, in a video context, is a single still image that, when played in sequence with the other frames of the video, creates motion on the playback surface. Analog frames are physical cels of film brought across a projector light at high speed. Digital frames are encoded by software implementing a codec. These frames may be a complete image or may be a transformation of other frames in the video sequence; clever removal of duplicated data and expressing it in terms of those transformations is the basis of much of digital video compression.
