Hardware implementation of digital watermarking system for real time captured image transmitting

The art and science of writing hidden message in to the digital media in such a way that no one apart from intended recipient knows existence of message called as steganography. The detection of hidden message by steganographically encoded packets called as steganalysis. In this paper a novel Steganographic technique using DWT (Discrete Wavelet Transform) and LSB (Least Significant bit) algorithm for transmitting captured images is proposed. LSB will used to hide data in least significant bit of pixel of an Image. The hardware implementation of the proposed method uses XPS & VB. Here MATLAB is used to convert the image in to the pixel format file. In XPS we select the required hardware and software component. Then by adding the source file and header file created in MATLAB & converted into bit streams and downloaded in to FPGA to get video frame.
