Realization of Multimedia Applications on Re-Configurable Platform

Digital images store large amount of data and in sequence. This information can be manipulated to several extend without being detected by human eyes. An example of such manipulations is supplement of secret information which is often referred to as information hiding. A successful supplement of a message into an image is more difficult using color images than that of gray scale images. A successful information hiding should result in the extraction of the hidden data from the image with high degree of data integrity. In this work we presents an information hiding technique that utilizes lifting schemes to effectively hide information in color images. We propose an information hiding techniques that utilizes lifting schemes to effectively hide information in images. In this proposed system we introduces a method of secret message encoding that makes use of wavelets. It makes use of the integer based wavelet transformation, lifting, and a least Significant Bits (LSB) approach to hide messages in covers images. In this work we have presented a new method of adaptive steganography with higher embedding capacity. The embedding capacity of the approach is controlled through the filter cut-off frequency. The approach was analyzed and shown to have a very high confidentiality due to the sharpness of information recovery with the cut-off frequency.
