Now here, we say add watermark means adding digital watermarking (text watermark or image watermark) into picture, to achieve the purpose of protecting picture. 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, for example. If the signal is copied, then the information is also carried in the copy.
Actually, there are two types of watermarking, visible and invisible watermarking. The visible watermark will display on the picture. Typically, the watermark may be text or a image which identifies the owner of the picture. The image on the right has a visible watermark. When the people can see the watermark, this is also a visible watermark. We add watermark to be visible here.
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.
Now, I will introduce the watermark, professional calls information. 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.
Whatever, 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 that information.
