A Secure Skin Tone based Steganography Using Wavelet Transform
16 Abstract—Steganography is the art of hiding the existence of data in another transmission medium to achieve secret communication. Steganography method used in this paper is based on biometrics. And the biometric feature used to implement Steganography is skin tone region of images [1]. Here secret data is embedded within skin region of image that will provide an excellent secure location for...
متن کاملA Secure Steganography Method Based on Integer Lifting Wavelet Transform
Steganography plays an important role in secret communication in digital worlds and open environments like Internet. Undetectability and imperceptibility of confidential data are major challenges of steganography methods. This article presents a secure steganography method in frequency domain based on partitioning approach. The cover image is partitioned into 8×8 blocks and then integer wavelet...
متن کاملReversible Image Steganography Based on Wavelets and Wavelet-like-transform
So far we have focussed on evaluating the performance of algorithms of irreversible image steganography in the ECCs domain and Transform domain for the grayscale and color images. In this Chapter we shall cover the two type of reversible image steganographic algorithms using the Companding technique (also called Reversible Thresholding Method) based on SLTPerceptual and Robust. We shall also gi...
متن کاملImage Steganography Method Using Integer Wavelet Transform
Digital Steganography explains the art and science of writing hidden messages in such a way that, apart from the sender and intended recipient, no one suspects the existence of the message, a form of security through the state of being unknown. The main two famous schemes used for image steganography are spatial domain embedding and transform domain embedding. The main aim of Wavelet Transform ...
متن کاملWavelet Steganography: An approach based on 3-level Haar Wavelet Transform
Secret communication over network has captured the imagination of researchers for many years. Steganography and Digital watermarking techniques are used to protect copyright information, address digital rights management, and conceal secrets. Secret data hiding techniques provide an interesting challenge for digital forensic investigations. Research into steganalysis techniques aids in the disc...
