Abstract

This paper shows two major techniques, the first is steganography and the second is filters. Gaussian and median filters are used to enhance the quality of image and remove the noise. Two kinds of noise are added to RGB cover image. RGB cover image are divided in to three cover images RGB. The hiding algorithm is Least Significant Bits (LSB) which is used to hide three different images in each part of noisy cover image. The results of proposed system show that the ability of extracting secret message without errors. Normalized Correlation (NC) and Peak Signal to Noise Ratio (PSNR) tests are utilized to find the robustness of the proposed system. The simulation results of this work are performed by Matlab program.
