Least significant bit steganography method for the digital data protection in the barcode

Abstract

In this paper, a computer program based on the least significant bit steganography method was developed. In the program, the message image (the original barcode) was inserted into cover image (false barcode) to produce the stego image barcode by this method. These two images were compared and validated by counting the Mean Square Error, the Root Means Square Error and the Peak Signal to Noise Ratio. The result shown that the program was proper because the Mean Square Error was 0.192314, Root Means Square Error was 0.438537 and the Peak Signal to Noise Ratio were 55.3247dB. we can conclude that the 1 least significant bit gave the best stego image.
