%X More and more people pay attention to the technology of information hiding because of the development of Internet and digital work.In the paper,a new scrambling method is introduced after analyzing the advantages and disadvantages of some other information hiding methods.It modifies the form of transformation matrix that is used to scramble the position and gray level of each pixel.This method changes not only the texture but also the statistical property of an image.Compared with other approaches,it has the following advantages: It improves the secrecy property of an image and reduces the attacker's notice;It has the less calculated capacity.Simulations show that it is practicable.
