%X The technique to hide secret information in some other data (carrier) without any apparent evidence of data exchange is called as Steganography. Previously steganographic techniques have limited information-hiding capacity.50¨C60% Data can be hidden after implementation of this paper . This technique is called Bit Plane Complexity Segmentation (BPCS) Steganography. In the traditional steganograhy techniques principle was either to replace a special part of the frequency components of the carrier image, or to replace all the least significant bits of a multi-valued image with the secret information. Our new steganography uses an image as the carrier data, and we embed secret information in the bit-planes of the carrier. This technique makes use of the characteristics of the human vision system whereby a human cannot perceive any shape information in a very complicated binary pattern. We can replace all of the ¨Dnoise-likeˇ¬ regions in the bit-planes of the carrier image with secret data without deteriorating the image quality. A typical carrier is a color image having Red, Green, and Blue color components in a multi-bit data structure.
