Improved Video Steganography Using Inter Pixel Value Coding

Steganography is the art of hiding information in ways that avert the revealing of hiding messages. This paper proposes a new efficient Video Steganography scheme. The design of algorithm enhances the entropy of the data scheme. To enlarge the capacity of the hidden secret information and to provide an imperceptible stego-image for human vision, a steganography approach called using inter pixel value coding (IPV) is used for embedding. The advantage of this algorithm is we need no decompression schemes for retrieval of data. Arnold transformation is performed to scrambles the secret image. This method is based on the real-time hiding of information in Video steganography. This method of steganography is very similar to the two dimensional image steganography. A new type of compressed video secure steganography (CVSS) algorithm is proposed. In this algorithm, embedding and detection operations are both executed entirely in the compressed domain, with no need for the decompression process. The results show that the proposed algorithm for modified steganography is highly secured with certain strength in addition to good perceptual invisibility. Here we took some effort to prove the entropy of given algorithm is better than the existing one.
