This paper focuses on a theme on DCT-based image digital watermark design and implementation. Improve a digital image watermarking algorithm which is based on DCT transform and Arnold The experimental results show that it is hiding the information of gray image, and make an and the gray level digital watermark value directly embedded into the DCT transform domain vector image from I, and the extraction process is the inverse of the embedded watermarking algorithm.
