Efficient Method for Hiding Data by Pixel Intensity

Data communication substructure has become more universal that there is absolutely no favoritism between different types of data in the carry plane of communication with each and every one skilled to carry it through the public data networks. Steganography technique is used to hide or embed data into an image or audio or video. Here the cover object used is an image. In the existing method for hiding and extraction of information from the given image three kinds of algorithm are used, based on its data and index channel of an image. In the proposed system, three kinds of hiding technique are implemented with some modifications in the logic level. Third algorithm is designed using color channels, based on its intensity. This technique would boost up the number of bits embedding in the image. The accomplishment of all the three algorithms are analyzed and the efficient one is taken into consideration while implementing in FPGA.
