performance evaluation of digital steganography using dwt

in the ever-changing world of global data communications, inexpensive internet connections, and fast-paced software development, security is becoming more and more of an issue. in the digital world, various schemes are adopted to hide data. the commonly used among those are steganography and watermarking. steganography is applying some cover image to protect data from intruder. in this paper, our main goal is to design a frequency domain based stenographic and evaluate it via different stego analysis measures such as mean square error (mse), peak signal-to-noise ratio (psnr), correlation, npcr, uaci, entropy and time evaluations.
