Abstract: A novel LSB-based image-hiding scheme that embeds secret data into
the grayscale cover image is proposed in this paper. Several LSB-based image
hiding schemes such as simple LSB substitution technique, optimal LSB
substitution technique, greedy LSB substitution technique, modulus LSB
substitution technique had been proposed. To provide good image quality of the
stego-image while requiring a low computational cost, the greedy method and
modulus function are employed in the proposed scheme. According to the results,
the proposed scheme provides better image quality of stego-image than the
comparative schemes while consuming a low computational cost.
