چکیده
In this paper, we present the privacy of the data protection during the transmission through a network based on stego analysis. The given text data is to be embedded on the image and audio should be encrypted. The data is divided into two parts and one part of data is stored in image and another part of data in the audio. The encryption of the data is done by Chaos Encryption method. Image watermarking is done by Adaptive Least Significant Bit Replacement method and audio watermarking is done by Singular Valued Decomposition method. Lifting wavelet transformation is applied to the host signal inorder to decompose it and then obtain the coefficients.

Watermarking Scheme Based on Multiple Chaotic Maps
a watermarking scheme for Grayscale image isproposed based on a family of the chaotic maps and discretecosine transform. Jacobian Elliptic mapis employed to encrypt ofwatermarked logo. Piecewise nonlinear chaotic map is also usedto determine the location of DCT coefficients for the watermarkembedding. The purpose of this algorithm is to improve theshortcoming of watermarking such as small key s...
متن کاملA Modified Digital Image Watermarking Scheme Based on Nonnegative Matrix Factorization
This paper presents a modified digital image watermarking method based on nonnegative matrix factorization. Firstly, host image is factorized to the product of three nonnegative matrices. Then, the centric matrix is transferred to discrete cosine transform domain. Watermark is embedded in low frequency band of this matrix and next, the reverse of the transform is computed. Finally, watermarked ...

متن کاملA Robust Digital Image Watermarking Scheme Based on DWT
In this paper a wavelet-based logo watermarking scheme is presented. The logo watermark is embedded into all sub-blocks of the LLn sub-band of the transformed host image, using quantization technique. Extracted logos from all sub-blocks are merged to make the extracted watermark from distorted watermarked image. Knowing the quantization step-size, dimensions of logo and the level of wavelet tra...
