FPGA Implementation of Image Steganography Algorithms using Generalized Exploiting Modification Direction and Pixel Segmentation Strategy

Synopsis:

             The generalized exploiting modification direction (GEMD) steganography algorithm is an enhancement of the exploiting modification direction (EMD) algorithm to hide a high payload capacity with maintaining the quality of the stego-image. In proposed system we developed a GEMD image steganography algorithm based on PSS-IB. The spatial domain techniques such as LSB based approach, EMD based approaches and Pixel Value Differencing (PVD) based approaches. The transform domain techniques, such as DCT, DWT and IWT The proposed algorithms have an embedding rate 3 x 0.5 xLVMA which is greater than R = 3 x (n + 1)/n of the GEMD method.

PROPOSED SYSTEM:

              In proposed system we developed a GEMD image steganography algorithm based on PSS-IB. The stego-image quality and the embedding payload capacity are two important parameters for steganography algorithms. The proposed algorithms have an embedding rate 3 x 0.5 xLVMA which is greater than R = 3 x (n + 1)/n of the GEMD method.

MERITS OF PROPOSED SYSTEM:

•         Less computational complexity
•         High embedding payload capacity
