For more security to the information and to enhance the hiding capacity of an image. A new strategy in image steganography here we propose the region - adaptive watermarking algorithm which will be used for the novel application to detect watermark attacks. The major advantages of the proposed watermarking detec tion technique are PSNR and RGB Intensity value. For tamper detection using linear classifier by providing these discriminating features. The watermark is embedded on different regions of the host image using a combination of discrete wavelet transform and singular value decomposition technique. Certain types of attack have occurred and there is a novel use the region - adaptive watermarking technique as a means to detect. At the same time, translation, scaling and rotation belongs to geometric attacks are al so applied. The severity of these attacks can be adjusted by modifying their corresponding parameter values. Our experimental results will detect the hiding data on the original image and also little relation to secret message file. For more security to th e information . It providing more helps
