“…Due to recent technical breakthroughs, it is now simpler than ever to manipulate and share digital multimedia files. However, this has raised concerns about the unauthorized copying of copy-protected media, and its protection is a challenging task [1][2][3]. The digital watermarking scheme was developed to handle such issues [4][5][6][7][8], and since then, it has been developed into a novel area of study and is generating substantial attention among scientists [9,10].…”

In recent years, digital image watermarking has gained a significant amount of popularity and developed into a crucial and essential tool for copyright protection, security, and the identification of multimedia content. Despite its high computational complexity, singular value decomposition (SVD) is an extensively utilized transformation in digital image watermarking. This research presents a robust and blind image watermarking scheme that directly alters the image pixels in the spatial domain to incorporate the watermark by quantizing the block-wise invariant maximum singular value. Using a distribution rule, pixels from the cover image are redistributed to obtain a new image that is divided into square and non-overlapping blocks to obtain invariant maximum singular values by using the matrix 2-norm in the spatial domain without performing an SVD transform. This modifies the pixels of the cover image such that the outcome is equivalent to the difference between the maximum singular values of the corresponding blocks in covers and watermarked images. The strengths of the proposed approach are highlighted by a comparison of experimental results with the most recent and comparable watermarking approaches.
