Watermark embedding mechanism using modulus-based for intellectual property protection on image data

In this paper, an intellectual property protection mechanism realized on a watermarking scheme is proposed. The embedding technique we adopted in this paper is based on the modular operation. The modulus is a threshold value which determines,how the binary pattern of watermark to be embedded into an image. In order to conduct a better fidelity of the image with the embedded watermark against the perception of human vision system, the random bit-string transformed from the watermark is done first. Then there are two classifications required to perform for the random bit pattern 0/1 during the embedding procedure. Afterwards, we issue several frequent image processing tests, such as JPEG compression, diverse filtering treatments, resampling and requantization, etc., to promote our remarkable result. Comparing to the previous literature in [12] as observed from the experiments, not only the advantages emphasized in [12] are remained, but also the original image is not necessary to check again so as to extract the embedded watermark. Therefore, the scheme explored in this paper is more efficient than the previous scheme, and it is feasible to cope with the protection of intellectual property on the digital image recognition.
