This paper presents an analytical study on the watermark specific embedding in the hybrid digital watermarking framework.Watermark is inserted in the modifications of singular values of SVD domain.To maximize the image imperceptibility and robustness of extraction with adequate security, three important study have been presented in this paper.The excellent re-constructional features of integer wavelet transform (IWT) have been integrated with DCT-SVD domain to obtain adequate visual quality of the watermarked image.The hybrid DCT-SVD features are proved to be sufficiently flexible in the image processing attacks condition.Impact of text image as watermark in the performance parameters have been presented and compared with other general image as watermark.SVD side matrix as a key information at the recipient end helps to avoid the rising FPP problem in SVD domain.The performance of the system have been judged in presence of various image processing attacks, in terms of parameters such as PSNR, NCC, BER, SSIM, and NSR values.The experimental results and analysis validates the scheme is sufficiently flexible to tackle attacks, and exhibits adequate imperceptibility and robustness.
