Highly Impartible Spatial Domain Steganography in Double Precision Images

Steganography is the craft of conveying a message by implanting it into interactive media information. Unlike cryptography, steganography hides the existence of information in interactive medium. There are various methods for hiding data in special and frequency domain. A speculation of the established LSB inserting strategy is performed in this technique. The double-precision binary floating format representation of dim level pictures requires 64 bit planes rather than the standard 8 planes of binary representation. Tested result demonstrate that, this plan beats the all established LSB technique. In 8-bit plane binary number, change in one bit causes large change in pixel value of cover image. Due to this reason error in stego image is comes out high. Unlike 8-bit plane, 64-bit plane floating point number causes very less error in stego image. This leads to high PSNR and high PSNR implies to large payload.
