Steganography is the science of concealing the existence of data in another transmission medium. It does not replace cryptography but rather boosts the security using its obscurity features. As proposed method is biometric steganography, here the biometric feature used to implement steganography is skin tone region of images. Proposed method introduces a new method of embedding secret data within the skin portion of the image of a person, as it is not that much sensitive to HVS (Human Visual System). Instead of embedding secret data anywhere in image, it will be embedded in only skin tone region.
