Now here, we say add watermark means adding digital watermark (text watermark or image watermark) to pictures in order to achieve the purpose of protecting them. According to Wikipedia, digital watermarking is the process of possibly irreversibly embedding information into a digital signal. The signal may be text, pictures or images. If the signal is copied, then the information is also carried in the copy.
Actually, there are two types of watermarking, visible and invisible. The visible watermark will display on the picture. Typically, watermark may be text or an image which identifies the ownership of the picture. Visible watermark on a picture can be seen directly by anyone who views this picture.
The invisible watermarking is a little complicated, its information is added as digital data to picture, but it cannot be perceived. Copyright protection system is an important application of invisible watermarking, which is intended to prevent or deter unauthorized copying of digital picture.
Usually, we add watermark means we put watermark information into photos. The information means the difference between the watermarked signal and the cover signal. The signal where embedded the watermark be called the host signal. Usually, a watermarking system is divided into three distinct steps, embedding, attack and detection. In embedding, an algorithm accepts the host and the data to be embedded and produces a watermarked signal.
Anyway, digital watermark could be text, pictures, images or something else which could be embedded into your photos for protecting your photo copyright; we also call it copyright information.
