Abstract

Stenography is the branch of information security that hides the important and crucial information into an innocent media in such a way that no one except recipient can extract the information. The major goal of the is to enhance communication security by inserting secret message into the digital image, modifying the nonessential pixel of the image. The main objective of this research is to secure the data so that human eye cannot detect the data hidden inside the image. The data embedding and extraction algorithm will be designed so that large information can be hidden in image and the quality of the Stego image will be good. A steganography technique is proposed of data hiding using the concept of 2 bit identical matching technique and OPAP technique. To make the stego image imperceptible use the concept of hiding data on edges as on edges there is sharp change in color intensity and human eye will be unable to detect any hidden data. To use optimal pixel adjustment process for edge pixels to decrease the mean square error and to increase the peak signal to noise ratio and hence to make the stego image more imperceptible. And then use 2 bit identical match technique for non edge pixels. Then hide data in every layer of image to increase the capacity. The parameters PSNR, MSE, BER are measured and compared to the results with literature.
