| Abstract: | This paper proposes a kind of novel information hiding Algorithm based on N dimensions Arnold and DCT transform.The encryption method,which transforms information into color image and employs N dimensions Arnold to scramble the color image is designed,it implements DCT transform on the carrier image in order to embed the scrambled image.It mainly includes N dimensions Arnold scrabbling image,the message embedding and extracting algorithm.Algorithm experiments are carried out with matlab6.5.The experiment re... |
