Research of colorde image digital watermark

Abstract

Digital watermarking is one of the effective technology which can protect the copyright of digital product and data security. For the encoding technology of color image, this paper proposed a method for embedding the watermarking using HSI color model. this paper propose an algorithm based on wavelet analysis, a colored watermark is embedded in a carrier, It embedded the image, which is disordered through ARNOLD transformation into the I space of the carrier image transformed. The results indicate that the watermarking technology proposed by this paper is secure and robust at resistance to compression and resistance to filtering. © 2012 Springer-Verlag GmbH.
