In this paper the authors have explored a new dimension in image steganography and propose a deft method for image - secret data - keyword (steg key) based sampling, encryption and embedding the former with a variable bit retrieval function. The keen association of the image, secret data and steg key, varied with a pixel dependent embedding results in a highly secure, reliable L.S.B. substitution. Meticulous statistical analysis has been provided to emphasize the strong immunity of the algorithm to the various steg-analysis methods in the later sections of the paper.
