Advancement in Lsb Steganography Technique using Modulus Function, Measuring Efficiency and Their Statistical Analysis

Steganography is an important area of research in recent years involving a number of applications. It is the science of embedding information into the cover image viz., text, video, and image (payload) without causing statistically significant modification to the cover image. The modern secure image steganography presents a challenging task of transferring the embedded information to the destination without being detected. In this paper we present a Modulo based image steganography that combines Least Significant Bit(LSB) technique on raw images to enhance the security of payload initially, the LSB algorithm is used to embed the payload bits into the cover image to derive the stego image. Then we are using binary based modulo after appending extra LSB bit and give output as stego image to enhance its security. It is observed that secure image with low MSE and BER are transferred without using any password, in comparison with earlier works.
