Advancements and Perspectives in Digital Image Watermarking

This paper investigates techniques for digital watermarking applied to images. It explores prior research on digital watermarks, presenting an analysis and outcomes of various watermarking methods. Digital watermarking involves concealing confidential information within original data to safeguard original rights. Spatial domain watermarking relies on pixel characteristics, whereas frequency domain watermarks involve various transformations applicable to digital content. The effectiveness of digital watermarking depends on the algorithm used, considering imperceptibility, robustness, security, complexity, and capacity. This paper delves into potential applications in detail.
