Abstract

Transmission of secret information provides an interesting problem space for investigating information hiding. In this paper we present a proposed hiding system “Single and Double Hiding (SDH)”, which can be used to embed text file in digital image and all will be hide in cover image or hide text file in cover image only. SDH is a flexible system, because its used variety types of image file format with different size such as (BMP, JPEG, GIF, and GIF-Animation), the proposed system gives a good result instead of sending encrypted message that draw suspicion, this is where Steganography can come into play. The system use cryptography, compression, and image filtering as auxiliary processes to recover the weakness in the previous methods, and its used three invented methods for hiding, which are Hiding in Edge Points, Direct Hiding, and Hiding with Reference Images. We present a comparison between (stego and cover) image through using the histogram and the difference distortion metrics, which are (MSE, SNR, LMSE, PSNR, NC, and CQ). Finally from the evaluation step the SDH system achieved the main goal of Steganography, since the resulting images didn’t draw any suspicion.
