Enhancing Data Security in Video Steganography using RSA Encryption, Huffman Coding with LSB Reverse

Abstract

In recent years, preventing data theft and securing the data is the main important measures in the field of digital communication technologies. For achieving the above measures, the image and video steganography are the most exceptional methodologies to hide the sensitive information in the cover medium for transferring the data over the open network. The Video steganographic algorithm has the advantage of huge concealment potential in these methods but neglects the protection when finding space. In balance the two things, each fulfills the high capacity in boost the video carrier load and can protect the confidential information securely. This paper proposes a new steganographic technique to cover the massive volume of information with the minimal distortion in a video file. In order to transfer the data with high level of security, cryptography method have been put forward. Also, this paper introduces steganography method that involves LSB reverse algorithm with RSA cryptography and lossless compression, so the message being sent is hidden in an exceedingly medium i.e video. The planned system is evaluated in terms of ordinary subjective measures like Mean Squared Error (MSE), and Peak Signal to Noise Ratio (PSNR). MSE and PSNR values are measured between the initial and therefore the steganographic files averaged overall video frames, to indicate the smallest degradation of the steganography video file. The experimental results show that this algorithm does not only have a nice visual and statistical invisibility, but the protection of secret information is also important and achieves the goal of protecting secret information effectively.
