Speaking of digital image watermarking, we can divide watermarks into two main groups ? visible and invisible watermarks.

Watermarking, a type of steganography, is a method for insinuating the name of the owner or creator of a digital object within the object for the purpose of asserting intellectual property.

A watermark is a kind of stamp, usually low opacity, that is placed on top of digital images. The stamp usually consists of a name, logo, or signature that identifies who created the watermark image, but sometimes it's intentionally big and obstructive.

Visible Watermarks ? These watermarks are visible. Invisible Watermarks ? These watermarks are embedded in the media and use steganography technique. They are not visible by naked eyes. Public Watermarks ? These can be understood and modified by anyone using certain algorithms.

Some simple watermark ideas include using the company logo, a copyright statement, or a website link. Without proper protection, organizations that invest time and resources in producing original content risk their assets being used by others, potentially impacting business opportunities and revenue.

On the basis of various applications, watermarking can be divided into three categories: Fragile Watermarking, Non-Fragile Watermarking and Robust Watermarking.

There are two main types of watermarks you should know about: Visible Watermarks. Invisible Watermarks.

Embedding methodSpread-spectrum watermarks are known to be modestly robust, but also to have a low information capacity due to host interference. A digital watermarking method is said to be of quantization type if the marked signal is obtained by quantization.

57, Mohanty et al. introduced six different type of popular watermarking: visible, non-visible, public, private, perceptual and bit-stream (see Fig. 3). According to Human Visual Perception, the watermarks can be categorized as Visible and Invisible watermarks.
