A Survey Paper on Data Transfer via Multimedia With Steganography Methodologies

Abstract

Many types of multimedia can be used to conduct pervasive communication like advertisements, posters, videos on TVs, audios, images etc. In this paper basically focuses on the security system based on the Digital Image processing techniques. We can detect and categorize an image feature using the Image Preprocessing Techniques. This paper explains a way to process a Message can be embedded in such images and extracted by a display-and-imaging fashion using smart phones. After applying basic image preprocessing techniques, the image will be again processed with algorithm for Signal-rich-art-image to extract certain kinds of secret information from the target image and infer the contents of an image. The extracted features data then compared with target data and that features are stored in standard database and can be classified. A message synchronization mechanism is also proposed to guarantee correct message extraction is also proposed.
