Abstract

Steganography is one of the most efficient data hiding techniques,
where a secret message is embedded in a cover image in such a
way that only the cover image is visible and at the receiver, the
hidden message is extracted from the stego-image. In this paper, a
modified Least Significant Bit (LSB) technique is proposed and
applied to different grayscale cover images in a spatial domain.
Furthermore, the proposed algorithm is implemented using FPGA,
which provides a least embedding time, a faster programmable and
commercial hardware solution for secure communication. The
obtained results prove that, the proposed algorithm has low
computational complexity, high embedding speed and the capability
of embedding a large payload capacity compared to other
algorithms that implemented in low cost embedded system
applications.
