Secured Cross Layered Watermark Embedding For Digital Image Authentication Using IWT - SVD

Abstract

In this paper, we are proposing a novel Integer Wavelet Transform(IWT) - Singular Value Decomposition(SVD) blind digital image watermarking scheme using hybrid transform to achieve higher imperceptibility, robustness, security and authenticity. In the proposed scheme, pseudo-random Latin square sequence is used for watermark encryption, encrypted watermark is divided and cross implant technique is used for embedding to overcome the problem of False Positive Problem (FPP). Further watermarking strengthening parameter is optimized using nature-inspired Artificial Bee Colony(ABC) algorithm, Simulation results shows that the proposed scheme has higher imperceptibility and robustness with different image modalities(gray-scale and colored). Performance comparison with some popular schemes shows that the proposed scheme surpass them in terms of robustness, imperceptibility and confidentiality.
