In recent years, there has been a substantial surge in the application of image watermarking, which evolved into an essential tool for identifying multimedia material, ensuring security, and protecting copyright. Singular value decomposition (SVD) discrete cosine transform (DCT) are widely utilized digital watermarking despite considerable computational burden they involve. By combining block-based direct current (DC) values with matrix norm, this research article presents novel, robust zero-watermarking approach. It generates zero-watermark without attempting to modify contents image. The is partitioned non-overlapping blocks, DC computed applying DCT. This sub-image further maximum singular each block calculated by norm instead SVD obtain binary feature matrix. A piecewise linear chaotic map encryption technique improve security watermark After that, created via XOR procedure between encrypted proposed scheme tested using variety distortion attacks including noise, filter, geometric, compression attacks. also compared other relevant methods outperformed them most cases.

In response to the growing digital media landscape, ensuring integrity and ownership of content is increasingly crucial. This study introduces an innovative image watermarking scheme that integrates Möbius transformations within discrete cosine transform spectrum enhance resilience invisibility. The embeds watermarks into middle-frequency coefficients images via geometric operations such as stereographic projections on complex plane. A genetic algorithm optimizes transformation parameters, achieving a balance between imperceptibility against typical processing attacks rotation, scaling, compression. experimental results show high imperceptibility, with peak signal-to-noise ratios consistently above 40 dB, minimal visual distortion. Robustness evaluations indicate watermark remains intact under various attacks, bit error rates significantly lower than those traditional methods. excels in distortions noise addition, surpassing existing techniques quality tamper resistance. By integrating for embedding, this approach offers robust imperceptible solution protection, presenting promising avenue rights management secure transmission. Future research will explore extending method other types further optimization techniques1.
