Video Steganography Using Lazy Wavelet Transform

Abstract

Steganography is the expertise skill of secret communication, concealing the very existence of communication. It resolute the issue of network security and favor secure communication through public and private channels. The hidden message can be in any format like text, audio, image or video. Nowadays, video files are drawing more and more attention. They are transmitted frequently on internet websites such as Instagram, YouTube etc dignifying a factual significance on video steganography. Video file usually consist of some identical frames, which are selected to hide the data. When video steganography is used, the anticipation to discover the secret information by an attacker is very less as compared to the other methods to hide data in a sequential manner. In this paper a modified technique has been used to embed the data. It involves the application of transformation to hide the encrypted data in cover file comprising of group of frames in sequential manner instead of using a single frame or image unlike existing video steganography methods [1]. The performance metrics such as Peak Signal to Noise Ratio (PSNR), RGB Intensity, Mean Square Error (MSE) and Data Recovery Ratio (DRR) have also been considered for experimental verification of the study. Simulation results are performed on MATLAB R2011b.
