High PSNR based Image Steganography

Abstract

Steganography is a method for inserting digital data within a different digital medium like text, pictures, sound signals, or film signals, while not exposing its occurrence in the medium. Information safekeeping is an essential necessary domain in correspondence medium over the web system. In this paper, working for improve the performance of Image Steganography. Results are showing comparison in between DCT-SVD and LWT-DCT-SVD. PSNR of proposed methodology is high as compare to DCT-SVD.
