A Multi Phase Model to Improve Video Steganography

Abstract

Steganography in multimedia object improves the information security during communication. An analysis approach with effective frame selection, partial information storage per frame and referenced mask based embedding is suggested to improve the steganograhy process in video objects. Three step process is espoused to amend the security of video object which is as under mentioned. In first stage, the effective frame selection analysis is performed using entropy method on which the information hiding is effective. The frame analysis is performed based on content level analysis. The adaptive mask over the frame is identified using frequency based analysis over the image in second stage. At third level, LSB approach is applied over the mask to perform information embedding. The work is applied on real time images. The obtained result shows the effective information storage with high PSNR ratio.
