Man toddled into a new era where huge monitors are replaced by palm size screens, and they boom alive to perform millions of activity in a millisecond!!! Seated in one place today, man can do just about anything with his portable palm size gadgets. But as the sizes of gadgets shrunk, iniquity and espionage magnified to monstrosity. Scientists over the years while devised techniques to shrink gadgets, also cerebrated algorithms to check the infraction. This paper proposes yet another method using the pixel indicator technology to increase the capacity of the message carrier; i.e. cover object. The pixel indicator is used to decide where the clandestine information has been embedded and to which colour plane of the cover image. Later how many clandestine data would be embedded on the chosen plane of the pixels is decided by the MSB of all the three planes. This proposed method also includes additional integrity check mechanism with improved randomness and hence the security. Simulation tests & complexity analysis were performed to evaluate the dexterity and complexity of the proposed algorithm.
