Embedding of Data in Motion Vectors by Using Steganography Concept
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 11
Abstract
This paper applies steganography algorithm in videos. In the proposed method, we take GOP techniques which are nothing but video algorithms so we use advantage of prediction types of MPEG bit streams to embed watermarks into both intra frame and non-intra frame with different residual masks. The experimental results show that the proposed steganography technique results almost invisible difference between the “STEGO FRAMES” and the original frames. Secrete Message is first encrypted by using cryptography algorithm. This encrypted message is converted into bits and replaced with the least significant bits of discrete cosine transform coefficients of frames in a video. By using cryptography we can provide high security to the embedded data. This algorithm was tested on different types of videos. The proposed method is found to perform well and is compared to a Least Significant Bit replacement algorithm from the literature.
