Secure RGB Image Steganography Based on Triple-A Algorithm and Pixel Intensity [ READ ]

Steganography is the art and science of writing hidden messages in such a way that no one, apart from the sender and intended recipient, even perceives the existence of the hidden message. In this paper, the concept of RGB intensity properties is being merged with randomization based Triple-A algorithm to increase the hidden capacity of the data-bits. Usually, storing variable number of bits in each channel (R, G or B) of pixel depend on the actual color values of that pixel. The concept- channels containing lower color values, can store higher number of data bits. This technique can be applied to RGB images where each pixel is represented by three bytes to indicate the intensity of Red, Green, and Blue of that pixel. This work shows more effective results, especially the capacity of the data-bits to be hidden with relation to the RGB image pixels.
