A Symmetric Steganography with Secret Sharing and PSNR Analysis for Image Steganography
Ajit Singh, Upasana Jauhari · 2012
Data transmission across networks is a common practice as per the development of Internet and multimedia technologies that gr ows exponentially today. The paper presented here is concerned with the secret sharing of message by hiding it in an image using the most commonly used LSB (Least Significant Bit) technique and later the calculations has been done for the PSNR (Peak Signal to Noise Ratio) of image in MATLAB. Steganography aimed at hiding the data invisibly within any media (image, audio, and video) so that it should be unnoticeable to the unintended person. Here the message to be sent is first encrypt with a key which enhance the security of message to another level.
