A JPEG Steganography Scheme Based on Skin Tone Detection

Abstract: Steganography is a process of hiding secret data into a cover medium so that invisible communication can be achieved. In this paper we present an efficient steganography method for JPEG images. This method uses JPEG image as a cover medium for hiding secret textual data. This JPEG steganography method is based on biometrics and to implement this skin tone detection biometric feature is used. In addition for secret data hiding Discrete Wavelet Transform (DWT) and Least Significant Bit (LSB) methods are used. And the performance of this JPEG steganography method is evaluated in terms of Peak-Signal-to-Noise Ratio (PSNR) and embedding capacity.

Keywords: Skin Tone Detection, DWT, LSB, MSE, PSNR.
