Abstract

Image based steganography uses the images as the cover media. LSB is a commonly used technique in this filed. Several scenarios of utilizing least significant bits within images are available. We merge between the ideas from the random pixel manipulation methods and the stego-key ones to propose our work, which uses the least two significant bits of one of the channels to indicate existence of data in the other two channels. This work showed attractive results especially in the capacity of the data-bits to be hidden with relation to the RGB image pixels.

Keywords: Steganography, RGB Bitmaps, Pixel Indicator Algorithm.
