The Secure Watermarking Of Digital Color Images By Using A Combination Of Chaotic Mapping

With the development of computer networks and data editing programs, the possibility of transferring or investigating digital data identity has encountered some difficulties. In this paper, some information is placed within images by using watermarking to verify the identity of images that will be destroyed by editing any of this information. Additionally, the slightest change watermarking methods that use chaotic maps are provided to enhance the sensitivity of these data. Then, a new method is proposed to insert one or two logo in a cover image and finally the necessary tests will apply on images. The proposed test and comparing the proposed approach with other methods show the high sensitivity and successful application of this method in images.
