ABSTRACT
Steganography is the one type of powerful technique which is science & art in which we have to write hidden messages, or we hide some important images, audio files, videos in this way that no-one, can find a hidden message which exists in cover images. Steganography is most strong techniques to mask the existence of unseen secret data within a cover object. Actually Stego means "Cover" graphy means "writing" that means It is nothing but we are hiding secret objects in cover image in which medium is different types of images. In practical feasible implementation practical approach would be to make the algorithm as strong as possible. In steganographic images are the most powerful objects that means cover objects, and therefore importance of image steganographic which can Embedding secret information inside images requires systematic computations. In this project, a PVD (Pixel value differencing) algorithm is used for Image Steganography in spatial domain. It is normalizing secret data value by encoding method to make the new pixel edge difference less among three neighbors (horizontal, vertical and diagonal) and embedding data only to less intensity pixel difference areas or regions. This algorithm shows a good improvement for input images compared to other algorithms. The strength of this scheme is that any random hidden/secret data do not make any shuttle differences to Steg-image compared to original image. The project results show as given below. This project is developed in Matlab.
