Aruna mittal6/10/2023 And the biometric feature used to implement steganography is skin tone region of images. Steganography method used in this paper is based on biometrics. It does not replace cryptography but rather boosts the security using its obscurity features. In this paper, Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication. And also satisfactory PSNR (Peak-Signal-to-Noise Ratio) is obtained. This study shows that by adopting an object oriented Steganography mechanism, in the sense that, we track skin tone objects in image, we get a higher security. in whole image, so cropped region works as a key at decoding side. Cropping results into an enhanced security than hiding data without cropping i.e. Different steps of data hiding are applied by cropping an image interactively. Secret data is hidden in one of the high frequency sub-band of DWT by tracing skin pixels in that sub-band. ![]() Additionally secret data embedding is performed using frequency domain approach-DWT (Discrete Wavelet Transform), DWT outperforms than DCT (Discrete Cosine Transform). For this skin tone detection is performed using HSV (Hue, Saturation and Value) color space. Here secret data is embedded within skin region of image that will provide an excellent secure location for data hiding. ![]() And the biometric feature used to implement Steganography is skin tone region of images.
