This paper described a method for image information hiding based on Fourier Transform.Images can be stored with the coefficients of Fourier Transform and can be displayed through Inverse Fourier Transform of Fourier Transform coefficients.In order to avoid others to get the true information of the image by the corresponding inverse processing method,these coefficients of Fourier Transform can be stored after scrambling.Then the simple Inverse Fourier Transform will not obtain the original images,so that we will achieve the purpose to encrypt and hid the digital image information.Simulation results show that the presented method of information hiding and protection is simple and has good security performances.
