Steganography is art of hiding the secure information. The propaganda may be embedded in all form of multimedia files.To hide the secret data, the binary image, intensity image or RGB images(true color image) are used as a cover images in the steganography. In existing proposals a normal architecture has been developed by using hardware for 8-bit pixel manipulation. In this proposed method, 24-bit will be manipulated simultaneously by the decoder and a maximum of 8 bits has been flipped to hide 12 bits in secret message in each pixel. Besides this methodology not only embed message in Least Significant Bits, but also hide the secret message in 5,4, 2 and 1 or any one of the likely arrangements. Comparison is made between the MSE and PSNR for existing and proposed system. In the proposed method the algorithm is implemented in the FPGA hardware in an efficient way , considering the hardware resources and power. |
