Abstract-Due to an aggressive development and covert transmission of the computer users over the web, the steganography is acquiring its vogue day by day. It is the method to encode the covert data in a transmission medium in a fashion that the actuality of data must remain hidden. To protect the integrity of the data over the internet becomes necessary for the high sensitivity communications or the data transfers. The steganography carries a number of options for the embedding of the secret data into the cover data. In this manuscript, we have proposed the hybrid representation for the embedding of the data, which utilizes the random pattern embedding along with the cryptography for the higher steganography security levels. The proposed model has been designed to enhance the security level by utilizing the sequential data encoding and decoding in the video data. The video embedding creates the higher level of security for the embedded data. The experimental results have been obtained in the form of the embedding capacity, mean squared error (MSE) and Bits per Pixel (BPP). The proposed model has been found to be efficient enough for the video steganography.
The rapid development of the transfer of data via internet made it easier to send the correct information and quicker to the destination. Today's massive demand of web applications needs the information to be communicated in a secure manner. The transmission of information in a public communication system isn't secure because of interception and improper manipulation by an eavesdropper. So for this problem, the solution is Steganography, which means the art of hiding information in ways that avert the revealing of hiding messages. Secure video steganography is a difficult task of sending the embedded data to the receiver without being detected. This paper presents a steganographic model which is based on random pattern based sequential bit encoding. The proposed model has been designed to enhance the security level. The video embedding creates the higher level of security for the embedded data. Here the encrypted secret image is embedded into the blocks of a cover video file which is selected using autocorrelation function which measures the similarity between the two images. The embedding is done on the basis of random selection of the pixels in the blocks of cover video. The performance parameters that are used to obtain results are taken in the form of chi-square histogram difference measurements. The proposed model increases the security by using random pattern embedding.Index Terms: Video steganography, cover video, random pattern, autocorrelation, chi square.
