Abstract :

Abstract - There are many  techniques to conceal the existence of hidden secret data inside a cover object. Steganography is one of the most powerful techniques. The bit-plane complexity segmentation steganography has good visual imperceptibility and high data embedding capacity compare to other steganographic techniques. 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. The bit-plane complexity segmentation (BPCS) steganography algorithm 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. The technique used in the BPCS steganograhy is to replace all of the noise-like regions in the bit-planes of the carrier image with secret data without deteriorating the image quality. With this we can remove the noise by replacing the noise present in the cover image. The design utilizes the Xilinx Spartan 3E Papilio one FPGA as well as specialized logic to perform the steganography steps. The design balances the tradeoffs such as imperceptibility, quality and capacity. The baud rate of 9600 bits per second may cause delay when we choose large image and huge amount of data.
