Steganography is an art of hiding information. There are several existing approaches, of which LSB is the popular known technique. While performing image steganography, there are certain limitations, in terms of time, robustness, distortion, quantity of data to hide etc. A common major limitation involved in these approaches is: altering the pixel value of the image which leads to distortion in the cover image. It can be easily detected by histogram and PSNR value. Zero Distortion Technique (ZDT) is proposed to overcome the limitation, as no changes are reflected in the histogram and PSNR value of the cover and the stego image. Experimental results on certain images shows that the proposed algorithm gives refine results. The proposed technique is robust, fast and helpful in providing security to our confidential data.
