Abstract: “This paper proposed a high payload image steganography method based on modulus parts of Kekre’s Advanced Multiple LSB Algorithm (KAMLA) and Lorenz chaotic map. In the proposed method a 256 by 256 color image is embedded in a 512 by 512 cover image with acceptable imperceptibility. Experimental results showed that proposed algorithm sustains a higher confidentiality and still can provide high capacity as compared to KAMLA hiding algorithm.”
