摘要：This paper presents a comparison between unoptimized and optimized video steganography. In today’s world of internet communication, video is considered to be an effective and important tool for communication. Video steganography is a technique of hiding secret information in the video frames or the audio beats of the given cover video so that the presence of the secret information is concealed. The un-optimized base technique used in this paper for video steganography is a 3-3-2 LSB based technique. The unoptimized video frames were then optimized using Modified Genetic Algorithm which generated an optimum imperceptibility of hidden data. Peak signal to noise ratio (PSNR), mean square error (MSE) and image fidelity (IF) are the important mathematical measures for analyzing any steganographic technique. In this paper, we have compared all these three parameters for both un-optimized and optimized video steganography. Experimental results show a considerable improvement in these parameters for the optimized video steganographic technique.
