| Abstract | ||
| Digital watermarking is technology that embeds various types of data (image, audio, or video…. etc) depending on the particular application and intended use. The information is encoded through subtle changes to image these changes typically would not be noticeable to a person viewing or listening to the content. Indeed, digital watermarks often are not perceptible by human at all, but rather are designed to be detected and decoded only by machines specifically programmed to do so. In general, any watermarking schema consists of two parts, the encoder (insertion algorithm) and the decoder (extraction algorithm). This paper, using coarseness equation to hide text watermarking in any bitmap reference to any field needs information to represent security for this field. So, this method gives higher randomize distributions according to the image properties | ||
