An Enhanced LSB based Video Steganographic System for Secure and Efficient Data Transmission

Abstract

The growth of high speed computing devices and Internet has made the Data communication very easy and fast. But this advancement has also increased the chances of getting the data snooped at the time of sending and receiving messages over network. So that Information has to be secured. In this paper, we proposed a method that uses Steganography. Steganography is a way of hiding secret information into a file (or any other thing that is convertible to Digital Format) and send it to the other end without being noticed. Proposed method takes Video as a carrier file and all the information is stored within that video file (that is called Video Steganography). The proposed method is based on Pixel Value Extraction of RGB model which uses Least Significant Bit insertion technique to insert the text within the Video file. Here the secret data is inserted into video frames after applying some checks onto it, related to its imperceptibility and capacity. In this paper we also have done some kind of Quantitative Analysis on different types of data. The result is evaluated in terms of Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE), that is, the output video file is compared to the original file, and we find minimal degradation that is quite imperceptible. Finally, we have some comparison drawn between some old methods with this new one.
