In this paper steganography is used to hide the data inside the images. Steganography is the science that involves
communicating secret data in an appropriate multimedia carrier, e.g., image, audio, and video files. The main goal of
steganography is to ensure that the transmitted message is completely masked, thereby ensuring that the message is accessible
only to the intended receiver and not to any intruders or unauthorized parties. This work focuses on the image steganography with
an image compression using least significant bit with 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.
