For many years information hiding has captured the imagination of researchers. Digital watermarking and steganography tools are used to address digital rights management, protect information, and conceal secrets. Digital watermark technology insert the information of copyright to the carrier, thus it aims to protect the carrier. The digital watermark is connecting two groups of data: Hidden data and carrier data. In the most situations, the carrier data will be distortion in the hiding process, and it unable to restore the initial state. That is, after even if the hidden body data already has been extracted, but the carrier data has also encountered the permanent distortion. But in certain applications, does not permit to the data pixel's minimum change. For example military remote sensing image, medicine image, high energy physics image, legal evidence and so on sensitive image. In these applications, any pixel's information thought that is very important. It can affect the image to data any revision the confidence level. These applications request to use the most primitive image data. The authors implemented image watermark based on Least Significant Bit Insertion method using Polynomial. The advantages and disadvantages of this method have also been discussed.
