摘要
En 中文
Steganography is one of the well-known data hiding methods, which is used in many security companies and government communications. In this technique, the various types of digital media can be used as a cover to hide secret information without impress the general form of them. Generally, key space and security are two important matters in most steganography methods, and they have the direct impact in proposed method's security. Moreover, Chaotic maps have been used in many data hiding algorithms to increase the security and key space of proposed schemes. The main reasons of using chaotic maps in steganography methods are sensitivity to initial conditions and control parameters. This paper proposes a new steganography technique based on new 3d sine chaotic map. This map is used in embedding and extracting processes to increase the security of the proposed algorithm. Satisfactory performance, acceptable image distortion and stronger robustness against some attacks are the main features of proposed method, and they are shown in experimental results. Comparison with some existing method shows that the quality and performance of the proposed algorithm are good, and it has high security and acceptable robustness against cropping and salt & pepper attacks.
