An Optimized FPGA Implementation of LSB Replacement Steganography Using DWT

Maya C S, Sabarinath G

This work focuses on the image steganography with an image compression using Discrete Wavelet Transform (DWT) on FPGA Spartan III Evaluation Development Kit (EDK). Current trends support digital image files as the cover file to hide another digital file with secret message or data. At receiver side, using Inverse Discrete Wavelet transform, both original image as well as hidden data can be successfully extracted. The design architecture when implemented on FPGA Spartan III offers a processing time of just 13.79 ns, which might give an impulse for the researchers to a very fast, programmable & cost effective hardware solution in the area of Secure Communication.
