Abstract In this paper, the main objective is an inter-frame data hiding in motion vectors and data hiding through intra-frame prediction method. Data hiding in the compression video is through motion vectors, i.e., embedding data in phase angle between two successive CMVs, with the best matching macroblock-based search. Another method is through 4 × 4 intra-prediction macroblocks. In this paper, we proposed two new advanced embedding scheme and steganography. By the inter-frame motion vectors and through intra-prediction modes, we can embed with more efficiency. The main advantage of the proposed method is that data hiding video is stego video and cannot understood by any hackers and maintains good perceptual quality of video.

1 Introduction For secrete communication copy right protection and authentication for new applications, data hiding is required for image and video processing, to avoid illegal activity or reproduce or manipulate them in order to change their owners identity. Digital water marking and data hiding are the techniques providing best embedding and copy right information in images and videos [1]. The aim of water marking is K.

not to restrict to the original image to access and ensure that embedding data again recoverable [1]. Developers seeking for providing protection on top of data encryption and scrambling for content protection. Developers seeking to protect owner information (water mark) embedded in original image or video. Cryptography converts into cipher text and it cannot be understood as shown in Fig. 1. A basic model of embedding and steganography is shown below. Data hiding techniques have become more important since two decades in various applications. For data hiding, so many techniques and algorithms introduced for digital images and videos. Nowadays, audio and video and picture frames with hidden copy right symbol help to avoid un authorized copying directly [2]. Hackers may modify the script of particular organization or revel the information to others. A lot of researches have been done in this field and many techniques are introduced, but due to drawbacks in techniques quality of video like sudden change in frames or noise is disturbed. All the above problems solved by high hiding techniques and steganography. Even though th
