摘要: Embedding maximum information in a stego-image with minimum change its appearance has been major concern image-based steganography techniques. In this paper, utilizing Genetic algorithm (GA) we have built up competent optimal robust technique. The watermarks are implanted into the HL and LH frequency coefficients bi-orthogonal wavelet transform (BWT). order to get better quality of stego image robustness develop an optimization technique using model explore for locations. We examine presentation suggested terms Peak signal Noise ratio (PSNR) Normalized correlation (NC). proposed is application confidential transmission symmetric key generated that can accomplish good imperceptibility
