Implementation of LSB Steganography and Its Evaluation for Various Bits

Steganography is the art of hiding information in information is gaining momentum as it scores over cryptography because it enables to embedd the secret message to cover images. Steganographic techniques offer more promise in digital image processing. The Least Significant Bit embedding technique suggests that data can be hidden in the least significant bits of the cover image and the human eye would be unable to notice the hidden image in the cover file. This technique can be used for hiding images in 24-bit, 8-bit or gray scale format. We emphasize strongly on image Steganography providing a strong focus on the LSB techniques in image Steganography. This paper explains the LSB embedding technique and presents the evaluation results for 2,4,6 Least significant bits for a .pngfile and a .bmp file.
