Random Scan Algorithm for Image Steganography in Scilab for Security Purposes

Abstract: In this paper, after entering the Secret Key the encrypted data is generated by determining their class. After that encrypted data is hidden in random bits of cover image using XORing method. By doing XORing the probability of pixel variation reduces as compared to replacing method as done in LSB or Modified LSB method. In this paper calculate the MSE, PSNR and Correlation Factor for Random Scan Algorithm in Scilab. In this paper also draw histograms between Cover image and Stego image to show how much Pixels variation.

Keywords: Steganography, MSE, PSNR.
