Abstract :
Watermark is a new effective digital copyright protection method and data security technology. A new scheme of image retrieval based upon digital watermarking has been proposed. First, embeds the binary watermark information in carried image, computes the value of NC (normalized correlation coefficient) between query watermark and extracted watermark,and gains the retrieval results. The watermarking algorithm is carried out in DCT (discrete cosine transform) domain, and extracting process is instantaneous and blind. The experimental results show that this method cannot only protect the copyright reliably, but also realize image retrieval effectively.
