%X In order to provide a large,scalable embedding capacity and maintain a good visual quality of the stego-image,In this paper, a secure steganography based on modulo and its cyclical characteristic is presented. First,the secret data stream is converted into an n-ary notational system data stream. Then,according to the characteristic of the remainder cycle,one n-ary notational information will be embedded into one pixel of the cover image by a modulus function with security features,until the secret data is embedded completely. Different parameter n gets different rates of embedding and visual quality of the stego-image. Theoretical analysis and experimental results show that the algorithm can maintain a high embedding rate while maintaining good visual quality of stego-image,and good security. The information-embedding rate is highly flexible,and the method can choose the steganographic scheme according to the actual requirements,for which the embedding rate and stego-image quality are ideal. It is more practical than other similar algorithns.
