摘要

Information hiding is one of the considerable objects in secret communication. Steganography is a vital research area in recent years relating several applications. Image steganography is the mode of embedding information (e.g. text) in an image, such an impossible to be seen by human eyes or so-called visual system (HVS). This study presents a steganography scheme based on a dynamic non-sequential Least Significant Bit (LSB) procedure for concealing text information into two kinds of images; include RGB images and Grayscale images, where the efficiency of using each of these kinds is studied. the spatial domain is used to perform the LSB procedure, where the bits of the secret message are inserted into the host or cover image using LSB process to outcome a stego-image. The results show that the secret message can be hidden securely and undetectable against HVS, and using RGB image shows better performance. Comparing with some other methods, the proposed scheme is superior in terms of MSE and PSNR.
