英文摘要 | In modern society, information security is becoming more and more important. There three useful methods to protect message, names watermarking, encryption, steganography with their own characteristics. Steganography aims at hiding secret message in a cover while has little influence on the cover, plays a more and more significant role. Many steganography algorithms have been proposed in different domains including time and transform domains. Most of the steganographia methods are based on binaryzation of the secret message, while a binary sequence is longer than a ternary sequence of a same decimal number. In this paper, in order to represent the secret message with a sequence less than its binaryzation, we propose a new method to map the secret message into two binary sequences and a ternary sequence. We propose a ‘ternary JSteg’ method to embed the ternary sequence, which can keep the histogram characters. Indeed, simulations show our method has less influence on the cover and has other advantages. |
