About the problem of colored watermark embedding,this paper introduces the least significant bit(LSB) algorithm in the digital watermarking technology,discusses the basic principles of image scrambling using Arnold transform,then proposes a type of colored watermark embedding algorithm in spatial domain based on Arnold transform.The simulation results show that the R,G,B components of a colored image are scrambled by Arnold transformed,then embedded into the least significant bit(LSB) of the carrier image.It can effectively achieve the colored watermark hidden,and the watermark has a good transparency and security.
