Abstract
This paper presents the new technique of the spatial domain image steganography for hidden electronic communication in grayscale and color images. The method hide one message bit per pixel and creates least changes in the statistical properties of the image. Experimental results, for the projected method, show the excellence of the method. The projected method is also implemented for two bits per pixel, three bits per pixel, four bits per pixel, five bits per pixel, six bit per pixel, seven bit per pixel and eight bits per pixel using the same concept. At the end the results shows that the method is good up to three bits per pixel.
Keywords: Communication, digital image, grayscale, electronic, mod function, RGB image, steganography, spatial domain.
